>> Doug LLOYD: Allura aħna jintefqu
about-- jekk matematika tiegħi hija tajba,

00:00:08,790 --> 00:00:11,900
U naħseb tfittex back-- I think
moħli madwar 35 videos jitkellem

4
00:00:11,900 --> 00:00:15,139
dwar l-aspetti varji ta 'C, forsi
ftit aktar, forsi ftit inqas.

5
00:00:15,139 --> 00:00:16,930
U aħna ma tkoprix
kollox C, iżda aħna

6
00:00:16,930 --> 00:00:21,170
koperti blokki kbar tal-
lingwa, il-maġġoranza vasta ta 'dan,

7
00:00:21,170 --> 00:00:22,882
ċertament għal użi komuni.

8
00:00:22,882 --> 00:00:25,090
Issa aħna qed tmur biex jitkellmu
dwar il-lingwa oħra, HTML.

9
00:00:25,090 --> 00:00:28,180
U aħna qed tmur biex ikopru
hija wieħed biss video.

10
00:00:28,180 --> 00:00:29,340
>> Iżda li għaddej biex tkun OK.

11
00:00:29,340 --> 00:00:31,410
Li għaddej biex attwalment isiru
xi ħaġa int ser jidraw.

12
00:00:31,410 --> 00:00:33,535
Issa li inti għandek l-
fundamenti tal-lingwa waħda,

13
00:00:33,535 --> 00:00:35,776
huwa attwalment pjuttost faċli
biex tibda t-tagħlim oħrajn.

14
00:00:35,776 --> 00:00:37,650
Allura aħna qed tmur biex tibda
li pass ftit lura

15
00:00:37,650 --> 00:00:43,340
u tleqqija fuq il-bażiċi
differenzi bejn dawn il-lingwi

16
00:00:43,340 --> 00:00:45,750
u tip ta 'tħallik lilha.

17
00:00:45,750 --> 00:00:48,530
Hemm ħafna ta 'verament kbir
riżorsi fuq l-internet, li

18
00:00:48,530 --> 00:00:51,279
aħna qed tmur biex tibda direzzjoni li inti
lejn minħabba li l-internet huwa

19
00:00:51,279 --> 00:00:53,340
repożitorju kbir ta 'informazzjoni.

20
00:00:53,340 --> 00:00:55,960
U għalhekk mhuwiex simili inti ser
tkun qed titlef neċessarjament

21
00:00:55,960 --> 00:00:58,349
billi ma l-informazzjoni
koperti fil-video.

22
00:00:58,349 --> 00:01:00,640
Int ser ikollok xorta tkun tista 'tikseb
dak kollu li għandek bżonn u l-użu

23
00:01:00,640 --> 00:01:03,590
l-għarfien inti stajt diġà
mibnija mill-fehim C

24
00:01:03,590 --> 00:01:07,130
li jagħmlu l-kurva tat-tagħlim għal dawn
lingwi oħra attwalment aktar fissa ħafna.

25
00:01:07,130 --> 00:01:08,640
Nwiegħed.

26
00:01:08,640 --> 00:01:12,770
>> Imma ejja nitkellmu dwar il-lingwa waħda
li tassew fundamentali għal kull web

27
00:01:12,770 --> 00:01:14,830
paġna, li hija HTML.

28
00:01:14,830 --> 00:01:18,230
HTML huwa l-Hyper Text Markup Language.

29
00:01:18,230 --> 00:01:22,700
HTML hija lingwa iżda huwa
mhux lingwa ta 'programmar.

30
00:01:22,700 --> 00:01:23,900
>> HTML ma jkollux varjabbli.

31
00:01:23,900 --> 00:01:26,430
Huwa ma jkollu loġika jew
funzjonijiet jew xi ħaġa bħal dik.

32
00:01:26,430 --> 00:01:30,301
Aħna ma tistax tagħmel xi
programmazzjoni per se fl HTML.

33
00:01:30,301 --> 00:01:32,300
Kultant inti ser tisma
nies jiddeskrivu lilhom infushom

34
00:01:32,300 --> 00:01:35,710
kif programmaturi HTML, li
mhuwiex kompletament preċiża.

35
00:01:35,710 --> 00:01:37,980
Aħna ma tistax tikteb programmi HTML.

36
00:01:37,980 --> 00:01:40,770
>> HTML huwa biss użati biex jiġu mmarkati l test.

37
00:01:40,770 --> 00:01:42,690
Huwa sejjaħ lingwa markup.

38
00:01:42,690 --> 00:01:47,680
U dak li din does-- dan markup--
nużaw tags HTML u dawn tags--

39
00:01:47,680 --> 00:01:51,600
dan markup-- semantikament
jiddefinixxi l-istruttura ta 'paġna

40
00:01:51,600 --> 00:01:55,280
u jikkaġuna l-kliem sempliċi li
teżisti bejn tags għandu jiġi interpretat

41
00:01:55,280 --> 00:01:57,320
billi browsers b'modi differenti.

42
00:01:57,320 --> 00:02:00,370
U forsi huwa aħjar li jispjegaw
b'dan il-mod minn ta 'illustrazzjoni.

43
00:02:00,370 --> 00:02:06,450
>> Hawn paġna HTML sempliċi ħafna, mhux
programm HTML, għal darb'oħra, paġna HTML.

44
00:02:06,450 --> 00:02:08,680
U nafu huwa ta '
Paġna HTML għaliex konna

45
00:02:08,680 --> 00:02:11,480
tmiss kollox ma 'tags HTML.

46
00:02:11,480 --> 00:02:13,850
Allura dan huwa dak li tag HTML Dehra.

47
00:02:13,850 --> 00:02:15,870
Huwa bejn parentesi angolu.

48
00:02:15,870 --> 00:02:18,570
U avviż fil-quċċata għandna
HTML u fil-qiegħ nett,

49
00:02:18,570 --> 00:02:21,400
wara we ghamilt dak li hu
apparentement ħafna HTML oħra,

50
00:02:21,400 --> 00:02:24,310
għandna angolu slash parentesi HTML.

51
00:02:24,310 --> 00:02:29,262
Allura dik it-tip ta 'l-konfini
bejn dak li huwa HTML u dak li mhux.

52
00:02:29,262 --> 00:02:32,220
U ovvjament, konvenzjonalment, just
kif inti kiteb kollha ta 'programmi C tiegħek

53
00:02:32,220 --> 00:02:35,300
ma estensjonijiet dot C,
kollha ta 'fajls HTML tiegħek

54
00:02:35,300 --> 00:02:37,909
se jispiċċa bil estensjonijiet dot HTML.

55
00:02:37,909 --> 00:02:39,200
Iżda hemm aktar jiġri hawn.

56
00:02:39,200 --> 00:02:40,658
Aħna mhux biss ikollhom dawn it-tags HTML.

57
00:02:40,658 --> 00:02:44,010
Aħna apparentement jkollhom din
ħaġa imsejħa tag ras.

58
00:02:44,010 --> 00:02:46,010
Ukoll, OK, x'hemm dan?

59
00:02:46,010 --> 00:02:48,550
>> Ukoll forsi huwa aħjar li
jiddistingwu permezz ta 'korp,

60
00:02:48,550 --> 00:02:50,590
korp huwa l-kontenut tal-paġna web.

61
00:02:50,590 --> 00:02:55,860
Hekk forsi l-tikketta ras jiddefinixxi Jittieħed
li mhuwiex fit-tieqa browser xierqa,

62
00:02:55,860 --> 00:02:59,410
iżda huwa b'xi mod importanti biex tagħna
paġna web li jirrendu korrett.

63
00:02:59,410 --> 00:03:02,490
Per eżempju, ġewwa tal-
tag ras għandna tags titolu.

64
00:03:02,490 --> 00:03:05,500
>> Allura titolu qed bonjour dinja,
li l-fatt se jkun dak

65
00:03:05,500 --> 00:03:08,797
juri fil-tab fil Chrome
jew safari jew Firefox--

66
00:03:08,797 --> 00:03:11,880
tkun xi browser inti prefer-- li l-
x'inhu għaddej li juru fit-titolu.

67
00:03:11,880 --> 00:03:14,800
U qabel tabs ikun juri
up fil-tieqa tiegħek browser kollu

68
00:03:14,800 --> 00:03:19,710
u inti tista 'biss ikollha paġna waħda
tiftaħ fi tieqa browser kull darba.

69
00:03:19,710 --> 00:03:22,160
Allura li għaddej biex tkun l-
titolu tal-paġna tiegħi fil-tab

70
00:03:22,160 --> 00:03:24,600
jew il-bar browser window, bonjour dinja.

71
00:03:24,600 --> 00:03:28,611
U allura l-kontenut ta 'tiegħi
paġna tal-web se jkun dinja, bonjour.

72
00:03:28,611 --> 00:03:31,360
Mela ejja tagħti ħarsa lejn dak li xi wħud
Ħaġa bħal din jista 'dehra.

73
00:03:31,360 --> 00:03:33,210
Din hija paġna HTML pretty sempliċi.

74
00:03:33,210 --> 00:03:35,970
Hekk jien hawn fil IDE CS50 tiegħi u
Stajt żżomjati fi ftit.

75
00:03:35,970 --> 00:03:38,290
U jien biss se
jiftħu bonjour dot HTML

76
00:03:38,290 --> 00:03:42,000
u nuruk li dan huwa pretty ħafna
il kontenut tal-paġna li rajna qabel.

77
00:03:42,000 --> 00:03:45,240
Tags sempliċi tiegħi HTML, ras,
tags titolu, korp, u l-bqija.

78
00:03:45,240 --> 00:03:47,320
Stajt inċiża li jkunu nodfa.

79
00:03:47,320 --> 00:03:51,530
>> U allura dak I tista 'tagħmel fil tiegħi
IDE huwa biss preview-paġna.

80
00:03:51,530 --> 00:03:52,630
U hemm immorru.

81
00:03:52,630 --> 00:03:56,070
Il-kontenut tal-paġna tiegħi huwa dinja,
hello, u jien ma tara xejn

82
00:03:56,070 --> 00:03:58,500
minn-tags ras hemmhekk.

83
00:03:58,500 --> 00:03:59,980
Huwa biss il-kontenut tal-ġisem.

84
00:03:59,980 --> 00:04:00,780
Dinja, bonjour.

85
00:04:00,780 --> 00:04:03,700
U għal darb'oħra l-korp biss
qal, dinja, bonjour.

86
00:04:03,700 --> 00:04:06,160
Il-parti l-oħra hija nieqsa.

87
00:04:06,160 --> 00:04:07,610
>> Allura li tassew kollox huwa.

88
00:04:07,610 --> 00:04:11,370
Din hija paġna sempliċi ħafna HTML bażiku.

89
00:04:11,370 --> 00:04:14,280
Issa stajt inċiża HTML tiegħi biex
jkun verament sbieħ u organizzata,

90
00:04:14,280 --> 00:04:15,840
imma jien ma attwalment ikollhom.

91
00:04:15,840 --> 00:04:17,959
I tista 'tagħmel ħarsa pretty ikrah.

92
00:04:17,959 --> 00:04:19,467
U dan xorta taħdem.

93
00:04:19,467 --> 00:04:21,050
Dan ikun l-istess paġna web eżatt.

94
00:04:21,050 --> 00:04:23,100
Stajt biss gotten rid ta
kollha ta 'l-ispazju abjad.

95
00:04:23,100 --> 00:04:24,820
>> Kif jirriżulta, l-ispazju abjad hija data.

96
00:04:24,820 --> 00:04:28,540
U hekk meta aħna qed tintbagħat data minn
mittent li riċevitur, mill-server

97
00:04:28,540 --> 00:04:30,670
lill-klijent, id-data jiswa l-flus.

98
00:04:30,670 --> 00:04:34,460
U għalhekk jwarrbu whitespace
huwa attwalment idea tajba

99
00:04:34,460 --> 00:04:37,320
jekk int xi ħadd li jservi
ta 'lott ta' kontenut web.

100
00:04:37,320 --> 00:04:39,820
Hija idea ħażina jekk int
xi ħadd li huwa tagħlim dan il-għalf

101
00:04:39,820 --> 00:04:41,528
u inti tixtieq li jkollok
dan nicely organizzata.

102
00:04:41,528 --> 00:04:43,810
Dan huwa ħafna aktar faċli biex parse minn dan.

103
00:04:43,810 --> 00:04:45,540
Iżda huwa funzjonalment identiċi.

104
00:04:45,540 --> 00:04:48,720
>> Il indentazzjoni u għalf bħal dik
fatt ma jimpurtax fil HTML.

105
00:04:48,720 --> 00:04:53,634
Uniku fatt rilevanti huwa tags ftuħ u
għeluq tags fl-ordni korretta.

106
00:04:53,634 --> 00:04:55,050
Avviż dak li ġara hawn, għalkemm.

107
00:04:55,050 --> 00:04:58,450
L-awment tagħtina mod biex
tikkomunika informazzjoni addizzjonali

108
00:04:58,450 --> 00:04:59,940
dwar dak li konna bil-miktub.

109
00:04:59,940 --> 00:05:03,130
Il-parti Hello, World kien
interpretat bħala t-titolu.

110
00:05:03,130 --> 00:05:06,410
U d-dinja, bonjour parti kienet
interpretat bħala l-kontenut

111
00:05:06,410 --> 00:05:09,090
jew dak li għandu jkun
viżibbli fuq il-paġna web tiegħi.

112
00:05:09,090 --> 00:05:12,167
>> Hemm aktar minn 100 minn dawn differenti
tags u lottijiet ta 'riżorsi kbira

113
00:05:12,167 --> 00:05:13,000
online biex isibu lilhom.

114
00:05:13,000 --> 00:05:14,900
Aħna qed tmur biex jitkellmu dwar
ftit minnhom f'dan il-video, xi

115
00:05:14,900 --> 00:05:16,440
mill-għalf verament fundamentali.

116
00:05:16,440 --> 00:05:18,440
Iżda aħna ma tkunx qed tmur talk
dwar dan kollu minħabba li

117
00:05:18,440 --> 00:05:20,250
ikun eżawrjenti li jagħmlu dan.

118
00:05:20,250 --> 00:05:22,880
>> Ħaġa oħra li tista 'tagħmel, għalkemm,
huwa jiftħu għodod iżviluppatur.

119
00:05:22,880 --> 00:05:26,069
U jekk inti recall minn
vidjo tagħna fuq HTTP,

120
00:05:26,069 --> 00:05:27,860
I spjegat kif tiftaħ
up għodod iżviluppatur.

121
00:05:27,860 --> 00:05:32,020
Fil Chrome huwa ġeneralment l-muftieħ F12
biex jinfetaħ is-toolbar iżviluppatur.

122
00:05:32,020 --> 00:05:35,909
Imbagħad minflok jagħżlu l-Netwerk
tab, inti tista 'tagħżel l-tab Elementi.

123
00:05:35,909 --> 00:05:37,700
U jekk inti tagħbija web
paġna, inti ser fil-fatt

124
00:05:37,700 --> 00:05:40,280
tara l-HTML li toħloq dik il-paġna web.

125
00:05:40,280 --> 00:05:44,090
U għalhekk inti tista 'titgħallem ħafna dwar HTML
billi tħares lejn websajts favoriti tiegħek

126
00:05:44,090 --> 00:05:48,474
u tara kif dawn jibnu l-
diversi biċċiet minnhom li tixtieq.

127
00:05:48,474 --> 00:05:50,890
Allura forsi hemm dan jibred
mudell jew xi ħaġa bħal dik.

128
00:05:50,890 --> 00:05:52,140
Kif dawn jagħmluha bl HTML?

129
00:05:52,140 --> 00:05:55,630
Well inti tista 'biss tiftaħ iżviluppatur tiegħek
għodod u imbagħad matul dak l-element

130
00:05:55,630 --> 00:05:57,700
u ara eżattament dak HTML jagħmilha.

131
00:05:57,700 --> 00:05:59,450
Allura dak verament
mod tajjeb biex jitgħallmu HTML,

132
00:05:59,450 --> 00:06:02,330
u I jirrakkomanda bil-qawwa li
inti tagħmel dan kemm biex jitgħallmu HTML

133
00:06:02,330 --> 00:06:04,930
u wkoll biex jitgħallmu ftit
ftit dwar xi wħud mill-għażliet

134
00:06:04,930 --> 00:06:07,050
disponibbli lilek fil
għodod iżviluppatur, li

135
00:06:07,050 --> 00:06:10,200
ċertament se jidħlu fil handy kif
tibda tagħmel web aktar intensiv

136
00:06:10,200 --> 00:06:11,090
programmazzjoni.

137
00:06:11,090 --> 00:06:14,080
>> Mela ejja tagħti ħarsa lejn
Koppja ta 'tags komuni HTML.

138
00:06:14,080 --> 00:06:17,210
U aħna ser jaqbżu u tagħti ħarsa lejn
liema dawn tags se tagħmlu wkoll

139
00:06:17,210 --> 00:06:20,490
billi tħares lejn xi fajls fil IDE tiegħi.

140
00:06:20,490 --> 00:06:26,330
Allura hawnhekk huma tliet tags bażika ħafna għall
tweaking l-apparenza viżiva tat-test.

141
00:06:26,330 --> 00:06:29,050
Hemm tags B, tags I, u tikketti U.

142
00:06:29,050 --> 00:06:33,170
U rispettivament dak li jagħmlu huwa
it-test bejniethom b'tipa grassa,

143
00:06:33,170 --> 00:06:35,430
korsiv, u għamlu enfasi.

144
00:06:35,430 --> 00:06:40,430
Mela ejja ara dak li look
bħal fuq sit web attwali IDE tiegħi.

145
00:06:40,430 --> 00:06:43,390
>> Allura hawn fil IDE tiegħi I jkollhom
fajl imsejħa BIU dot HTML.

146
00:06:43,390 --> 00:06:46,770
BIU dot HTML biss qed
grassa, korsiv, b'enfasi fuq.

147
00:06:46,770 --> 00:06:47,830
I ser tiftaħ it up.

148
00:06:47,830 --> 00:06:51,810
>> U aħna ser tara li hawn I
jkollhom dan it-test huwa tags B bold.

149
00:06:51,810 --> 00:06:54,010
Dan it-test huwa tags I korsiva.

150
00:06:54,010 --> 00:06:56,307
U dan it-test huwa tags U enfasizzat.

151
00:06:56,307 --> 00:06:57,640
X'inhu dan se look like?

152
00:06:57,640 --> 00:06:59,473
Well darb'oħra, kollha I jkollhom
tagħmel hu li tmur minn hawn

153
00:06:59,473 --> 00:07:04,690
lill-browser tiegħi, fajl browser tiegħi, ikklikkja
Preview, u dan huwa dak li taqa up.

154
00:07:04,690 --> 00:07:07,520
>> It-test bejn il-B
tags huwa tabilħaqq issa bold.

155
00:07:07,520 --> 00:07:10,720
It-test fl bejn il-I
tags huwa tabilħaqq issa korsiva.

156
00:07:10,720 --> 00:07:14,634
U t-test bejn il-U
tags huwa tabilħaqq issa enfasizzat.

157
00:07:14,634 --> 00:07:15,550
Allura dak pjuttost tajba.

158
00:07:15,550 --> 00:07:18,450
Aħna issa jkunu jafu kif jagħmlu test
tfittex ftit aktar fancy

159
00:07:18,450 --> 00:07:20,360
jew li jiġbdu enfasi li ċerti affarijiet.

160
00:07:20,360 --> 00:07:25,530
Ieħor ftit tags komuni hawn huma
paragrafu tags, tags P, u header,

161
00:07:25,530 --> 00:07:27,980
li stajt mogħtija hawn bħala Hx.

162
00:07:27,980 --> 00:07:32,520
>> Dawn it-tabelli P, dawn paragrafu tikketti,
break test tiegħek up fis paragrafi.

163
00:07:32,520 --> 00:07:34,646
Mhuwiex biżżejjed li biss
hit jidħlu u jħallu spazji,

164
00:07:34,646 --> 00:07:37,186
minħabba kompjuter hija biss ser
li tagħmel dak li għid li tagħmel

165
00:07:37,186 --> 00:07:39,450
u tinjora abjad
ispazju għall-parti l-kbira.

166
00:07:39,450 --> 00:07:41,636
Allura ma nistgħux biss hit Ikteb
u jistennew kompjuter tagħna

167
00:07:41,636 --> 00:07:43,760
li tinterpreta li aħna rridu
li jibdew paragrafu ġdid.

168
00:07:43,760 --> 00:07:47,670
Irridu ngħidu b'mod espliċitu ħafna dan
hija waħda paragraph-- dan huwa another--

169
00:07:47,670 --> 00:07:50,740
billi tagħlaq kull f'sett ta 'tikketti P.

170
00:07:50,740 --> 00:07:54,560
>> U għandna wkoll dawn l-għażliet
għall tags H, dawn it-tags header.

171
00:07:54,560 --> 00:07:57,000
Illum għandna sitt livelli differenti
ta 'headers, wieħed, tnejn, tlieta,

172
00:07:57,000 --> 00:08:01,110
erba ', ħames, u sitta, li huma
progressivament akbar u akbar

173
00:08:01,110 --> 00:08:01,710
headers.

174
00:08:01,710 --> 00:08:04,360
U huma jiksbu iżgħar u
iżgħar u iżgħar.

175
00:08:04,360 --> 00:08:07,690
Allura aħna għandna header ogħla livell, it-tieni
header livell, u l-bqija, u l-bqija.

176
00:08:07,690 --> 00:08:10,480
>> Ejja tagħti ħarsa lejn forsi xi
Tags P u xi tags header

177
00:08:10,480 --> 00:08:13,110
fl-azzjoni fuq paġna web.

178
00:08:13,110 --> 00:08:18,180
Allura hawn fil IDE tiegħi I jkollhom fajl imsejjaħ
PH dot PH jkunu paragrafi HTML,

179
00:08:18,180 --> 00:08:18,970
u tags header.

180
00:08:18,970 --> 00:08:20,709
Iftaħ li up.

181
00:08:20,709 --> 00:08:23,000
Hemm ħafna jiġri hawn
għaliex stajt jqajjem xi Lorem

182
00:08:23,000 --> 00:08:24,660
ipsum, xi test biss każwali fil hawn.

183
00:08:24,660 --> 00:08:27,284
So I ser zoom out ftit
għaliex hemm daqstant għaddej.

184
00:08:27,284 --> 00:08:31,980
Imma avviż li għandi fil-ħafna
top hawn I jkollhom H1, livell wieħed,

185
00:08:31,980 --> 00:08:32,802
tag header.

186
00:08:32,802 --> 00:08:36,010
Imbagħad I jkollhom paragrafu, li huwa biss
mazz ta 'Lorem text-- każwali ipsum--

187
00:08:36,010 --> 00:08:38,720
biss default mili standard fit-test.

188
00:08:38,720 --> 00:08:41,970
So I għandhom żewġ paragrafi ġewwa ta 'dak
livell wieħed header u mbagħad stabbiliti hawn taħt I

189
00:08:41,970 --> 00:08:46,850
jkollhom livell ta 'żewġ header hawn fuq il-linja 24,
tieni header livell, u tnejn oħra

190
00:08:46,850 --> 00:08:47,840
paragrafi.

191
00:08:47,840 --> 00:08:51,910
Ukoll dan xi look like
jekk I tarah fil preview tiegħi?

192
00:08:51,910 --> 00:08:53,790
Ejja naraw.

193
00:08:53,790 --> 00:08:55,730
>> Allura avviż li l-
ewwel header livell hawn

194
00:08:55,730 --> 00:08:58,420
huwa attwalment pjuttost ftit akbar
mit-tieni header livell.

195
00:08:58,420 --> 00:08:59,940
Allura aħna użati tags H1.

196
00:08:59,940 --> 00:09:03,820
U tinnota li l-tags P inessu
break affarijiet fil-paragrafi.

197
00:09:03,820 --> 00:09:07,500
Jekk kellna gotten rid ta 'dawk tags P
u fil-fatt imqiegħda biss Jidhol jew Returns

198
00:09:07,500 --> 00:09:10,110
bejn dak li aħna ttamat kieku
jkun il-paragrafi differenti,

199
00:09:10,110 --> 00:09:13,193
huma kollha biss slam flimkien u
ma jkollhomx dan il-paragrafu sbieħ

200
00:09:13,193 --> 00:09:15,840
separazzjoni bi spazju fuq u taħt.

201
00:09:15,840 --> 00:09:18,300
U hekk dan huwa dak paragrafu
tags u tags header

202
00:09:18,300 --> 00:09:22,440
huma komunement użati biex jagħmlu biex tiġbed
attenzjoni għall-porzjonijiet tal-paġna web tagħna

203
00:09:22,440 --> 00:09:23,550
b'dan il-mod.

204
00:09:23,550 --> 00:09:27,560
>> Up li jmiss huma xi tags li nużaw
biex jibnu listi fuq il-paġna web tagħna.

205
00:09:27,560 --> 00:09:30,820
Allura aħna għandna unordered
lists-- ULs-- li huma biss

206
00:09:30,820 --> 00:09:34,090
listi bulleted, ordnati
lista li huma numbered--

207
00:09:34,090 --> 00:09:37,680
OLs-- u ġewwa ta 'jew
wieħed minn dawk għandna bżonn li jkollhom

208
00:09:37,680 --> 00:09:40,600
settijiet ta 'kif jindikaw jelenkaw punti, LI.

209
00:09:40,600 --> 00:09:44,370
U hekk aħna tag UL miftuħa
u aħna jpoġġu punti ġewwa ta 'dan.

210
00:09:44,370 --> 00:09:46,920
U allura meta aħna qed isir ma '
li, nistgħu tagħlaq il-tag UL.

211
00:09:46,920 --> 00:09:49,850
>> U l-istess jista 'jkollna
lista ordnati jew nnumerati

212
00:09:49,850 --> 00:09:51,560
u mqiegħda jelenkaw punti ġewwa ta 'dan.

213
00:09:51,560 --> 00:09:53,350
Mela ejja tagħti ħarsa
lejn koppja ta 'listi

214
00:09:53,350 --> 00:09:57,230
u dak li kieku
tirrendi fuq IDE CS50.

215
00:09:57,230 --> 00:10:00,640
So I jkollhom hawn fil IDE tiegħi
fajl imsejħa listi dot HTML.

216
00:10:00,640 --> 00:10:03,100
Ejja tagħti ħarsa.

217
00:10:03,100 --> 00:10:08,482
>> U avviż hawn I jkollhom unordered
lista ma 'ħames affarijiet fih.

218
00:10:08,482 --> 00:10:11,440
U mbagħad I jkollhom lista ordnat, u
Stajt biddel il-lametta ftit,

219
00:10:11,440 --> 00:10:11,939
id-dritt?

220
00:10:11,939 --> 00:10:13,152
Stajt qal bidu ugwali sitta.

221
00:10:13,152 --> 00:10:16,110
Jirriżulta ma 'lista ordnat I
tista 'tistabbilixxi l-punt tat-tluq fejn

222
00:10:16,110 --> 00:10:20,130
I want-- kontumaċja se jkun one--
billi sempliċement tiżdied din l-hekk imsejħa attribut

223
00:10:20,130 --> 00:10:21,190
li tag OL tiegħi.

224
00:10:21,190 --> 00:10:23,572
U għalhekk din il-lista se
jibdew jingħaddu mill-sitta.

225
00:10:23,572 --> 00:10:26,780
Allura l-elementi ta 'dik il-lista nnumerati
għandu jkun sitt, seba ', tmien, disa', għaxra,

226
00:10:26,780 --> 00:10:29,930
għaliex hemm ħames elementi
fil-lista, għall-kuntrarju wieħed,

227
00:10:29,930 --> 00:10:33,770
tnejn, tlieta, erba ', ħames, li
ikun il-każ jekk I kien qal OL

228
00:10:33,770 --> 00:10:36,730
mingħajr ma tispeċifika l-attribut bidu.

229
00:10:36,730 --> 00:10:41,594
>> Allura aħna ser biss preview dan sabiex inti tista '
jiksbu sens ta 'x'inhu għaddej hawn.

230
00:10:41,594 --> 00:10:42,260
U hemm immorru.

231
00:10:42,260 --> 00:10:44,610
Hemm lista tiegħi.

232
00:10:44,610 --> 00:10:47,810
L-ewwel ħames elementi huma
listi unordered jew bulleted.

233
00:10:47,810 --> 00:10:51,010
U l-ħames elementi li ġejjin
huma lista ordnat separata

234
00:10:51,010 --> 00:10:52,980
jibdew minn sitt.

235
00:10:52,980 --> 00:10:56,247
Allura li kif nistgħu
jibnu listi jużaw HTML.

236
00:10:56,247 --> 00:10:58,080
Ħaġa oħra li inti tista '
tixtieq li tagħmel ma HTML

237
00:10:58,080 --> 00:11:01,520
tinbena tabella ta
informazzjoni ta 'ringieli u kolonni

238
00:11:01,520 --> 00:11:04,560
biex jippreżentaw l-informazzjoni
partikolarment organizzati mod.

239
00:11:04,560 --> 00:11:09,110
Biex tagħmel dan ma HTML jista 'jkollna
definizzjoni tabella bidu parentesi miftuħa

240
00:11:09,110 --> 00:11:10,160
tabella.

241
00:11:10,160 --> 00:11:14,680
U allura ġewwa ta 'dik it-tabella aħna
jista 'jkollhom sett ta' ringieli, tags TR

242
00:11:14,680 --> 00:11:15,980
biex jindikaw kull ringiela.

243
00:11:15,980 --> 00:11:22,510
U mbagħad tags TD mur ġewwa ta 'tikketti TR
li tispeċifika kolonna fi filliera.

244
00:11:22,510 --> 00:11:24,340
>> Għaliex huwa msejjaħ TD u mhux TC?

245
00:11:24,340 --> 00:11:25,940
Ukoll, TD stands għal data tal-mejda.

246
00:11:25,940 --> 00:11:27,900
Normalment int tqegħid
informazzjoni tiegħek hemmhekk.

247
00:11:27,900 --> 00:11:29,440
Allura hu għalhekk li huwa TD u mhux TC.

248
00:11:29,440 --> 00:11:31,140
Huwa ftit konfuża.

249
00:11:31,140 --> 00:11:33,720
>> Allura inti għandek tags mejda u
ġewwa tal tags mejda tiegħek

250
00:11:33,720 --> 00:11:35,600
għandek numru ta 'ringieli, TRs.

251
00:11:35,600 --> 00:11:40,030
U ġewwa kull ringiela għandek
TDS għan-numru ta 'kolonni

252
00:11:40,030 --> 00:11:42,880
li inti tixtieq li jkollok
f'dak ringiela partikolari.

253
00:11:42,880 --> 00:11:47,730
Ejja tagħti ħarsa lejn ħafna
tabella sempliċi fuq fil IDE CS50.

254
00:11:47,730 --> 00:11:49,730
>> So I hawn fajl
imsejħa tabella dot HTML.

255
00:11:49,730 --> 00:11:53,390
Ejja jkollhom ħarsa lejn
dak li qisu.

256
00:11:53,390 --> 00:11:56,225
Hemm ħafna jiġri hawn, iżda
jekk tinnota I jkollhom tabella miftuħa.

257
00:11:56,225 --> 00:11:57,850
Jien jibdew id-definizzjoni mal-mejda.

258
00:11:57,850 --> 00:12:02,100
U mbagħad fl-ewwel filliera tiegħi I apparentement
jkollhom erba 'kolonni, wieħed, tnejn, tlieta,

259
00:12:02,100 --> 00:12:02,660
erbgħa.

260
00:12:02,660 --> 00:12:04,290
U allura jien jsir ma 'dak ringiela.

261
00:12:04,290 --> 00:12:07,750
>> Imbagħad I tibda ringiela ieħor u
do tnejn, erba ', sitt, tmien.

262
00:12:07,750 --> 00:12:08,850
Finish dak ringiela.

263
00:12:08,850 --> 00:12:11,410
Do ringiela ieħor, tlieta, sitta, disa, 12.

264
00:12:11,410 --> 00:12:14,830
U mbagħad aħħar ringiela, erba,
tmienja, 12, u għalkemm huwa

265
00:12:14,830 --> 00:12:16,560
ftit maqtugħa hawn, 16.

266
00:12:16,560 --> 00:12:17,710
>> I lest li filliera.

267
00:12:17,710 --> 00:12:18,970
I lest il-mejda.

268
00:12:18,970 --> 00:12:21,430
U allura jien jsir ma HTML tiegħi.

269
00:12:21,430 --> 00:12:22,590
Xi jfisser dan look like?

270
00:12:22,590 --> 00:12:26,014

271
00:12:26,014 --> 00:12:27,430
Ukoll, mhuwiex verament ħafna biex tara.

272
00:12:27,430 --> 00:12:31,690
Stajt organizzata b'mod ċar informazzjoni tiegħi
b'mod kemmxejn aktar organizzati.

273
00:12:31,690 --> 00:12:33,755
Imma din mhix super pretty hawn.

274
00:12:33,755 --> 00:12:36,130
U aħna qed tmur biex jittrattaw
li meta nitkellmu dwar CSS.

275
00:12:36,130 --> 00:12:38,930
Aħna ser tirrevedi din l-idea ta '
dak li nagħmlu biex jagħmlu table--

276
00:12:38,930 --> 00:12:41,260
forsi format ftit aħjar?

277
00:12:41,260 --> 00:12:45,070
Imma jien xorta jkollhom erba 'ringieli,
kull wieħed minnhom għandu erba 'kolonni,

278
00:12:45,070 --> 00:12:48,890
u verament dak li dan jammonta għal huwa
sempliċi ħafna erbgħa minn erba 'multiplikazzjoni

279
00:12:48,890 --> 00:12:49,870
tabella.

280
00:12:49,870 --> 00:12:51,690
>> Just ftit tags aktar aħna ser nitkellmu dwar.

281
00:12:51,690 --> 00:12:54,617
Ejja nitkellmu dwar il-
kunċett ta 'forma HTML.

282
00:12:54,617 --> 00:12:57,450
Allura inti tista raw dan fil-
kuntest ta jillogja web page.

283
00:12:57,450 --> 00:12:59,100
Normalment inti tip fl-isem l-utent tiegħek.

284
00:12:59,100 --> 00:13:01,510
Inti tip password tiegħek,
u int tajba biex tmur.

285
00:13:01,510 --> 00:13:04,170
Dan ikun il-bidu ta 'forma.

286
00:13:04,170 --> 00:13:05,420
>> Taqbeż is-site fuq div tieni.

287
00:13:05,420 --> 00:13:07,987
Għandna wkoll inputs li
tip ta 'tajbin ġewwa ta' forom.

288
00:13:07,987 --> 00:13:10,320
Dawn huma l-elementi li
int fil-fatt ittajpjar fi,

289
00:13:10,320 --> 00:13:12,580
jew il-buttuni tar-radju int
timmarka, jew b'ċekk

290
00:13:12,580 --> 00:13:14,310
kaxxi li int timmarka off.

291
00:13:14,310 --> 00:13:15,770
Allura dawn imorru ġewwa ta 'forom.

292
00:13:15,770 --> 00:13:18,500
U huma jinkludu bażikament
kull ringiela tal-formola

293
00:13:18,500 --> 00:13:19,887
jekk formola tiegħek hija ifformattjat sew.

294
00:13:19,887 --> 00:13:22,220
Imbagħad hemm dan il-kunċett ta '
a div, li ma verament

295

ta 'tikketti bħal dawk stajt

296
00:13:25,060 --> 00:13:26,170
qed tagħmel qabel.

297
00:13:26,170 --> 00:13:29,790
Hija biss it-tip ta tiddemarka l-
bidu ta 'xi division-- arbitrarja

298
00:13:29,790 --> 00:13:31,670
div-- tal-paġna.

299
00:13:31,670 --> 00:13:33,210
M'hemm l-ebda waqfa viżwali.

300
00:13:33,210 --> 00:13:34,800
M'hemm l-ebda linja.

301
00:13:34,800 --> 00:13:37,180
Mhuwiex tpaċi bħala
blokki separata awtomatikament.

302
00:13:37,180 --> 00:13:39,430
Youd għandek stil lilha
li mod biex tagħmel dan.

303
00:13:39,430 --> 00:13:42,110
>> Hija biss it-tip ta 'tgħid Irrid
biċċa ta 'spazju fuq il-paġna web tiegħi,

304
00:13:42,110 --> 00:13:45,190
u jien biss ser sejħa
dan din id-diviżjoni tal-paġna tiegħi.

305
00:13:45,190 --> 00:13:47,619
Nistgħu npoġġu Jittieħed ġewwa
tal divs, u fil-fatt,

306
00:13:47,619 --> 00:13:49,410
meta aħna ras fuq
IDE fit-tieni, aħna ser

307
00:13:49,410 --> 00:13:53,760
tara li jien tqegħid tiegħi
jiffurmaw ġewwa ta 'div.

308
00:13:53,760 --> 00:13:57,050
>> So I jkollhom hawn fil IDE tiegħi
fajl imsejħa div forma dot HTML.

309
00:13:57,050 --> 00:13:59,260
Ejja jiftħuh.

310
00:13:59,260 --> 00:14:01,460
Avviż li bħal I said,
div huwa tip ta arbitrarja.

311
00:14:01,460 --> 00:14:01,640
Dritt?

312
00:14:01,640 --> 00:14:02,973
Hija ma verament tfisser xejn.

313
00:14:02,973 --> 00:14:05,140
So I jkollhom arbitrarja
ewwel diviżjoni tal-paġna tiegħi.

314
00:14:05,140 --> 00:14:07,848
U allura minflok div ieħor
aktar tard, li jibdew fuq il-linja tmienja,

315
00:14:07,848 --> 00:14:08,730
Għandi din il-formola.

316
00:14:08,730 --> 00:14:13,594
U ġewwa tal-formola I jkollhom
numru ta 'inputs, oqsma tal-formola.

317
00:14:13,594 --> 00:14:16,510
So I jkollhom qasam li ismu huwa A--
li ma verament tfisser xejn

318
00:14:16,510 --> 00:14:19,350
now-- dritt li apparentement
jieħu test, ieħor li

319
00:14:19,350 --> 00:14:22,630
jieħu password, ieħor li l-Radju

00:14:22,630 --> 00:14:24,797
u ieħor li l-buttuna issottometti.

321
00:14:24,797 --> 00:14:26,630
Ukoll, dak ma dan
kollu li jkun effettivament look like?

322
00:14:26,630 --> 00:14:27,629
Well, ejja tagħti ħarsa.

323
00:14:27,629 --> 00:14:31,010
Aħna ser tiftaħ it up fil-tieqa preview tagħna.

324
00:14:31,010 --> 00:14:33,557
Avviż li dan arbitrarja

325
00:14:33,557 --> 00:14:34,640
ebda separazzjoni viżwali hawn.

326
00:14:34,640 --> 00:14:37,150
Hija ma verament tagħmel xejn, id-dritt?

327

U jien ma tagħmel ebda ifformattjar speċjali.

329
00:14:39,890 --> 00:14:42,680
Allura l-forma hija biss waħda
ringiela kbira ta 'informazzjoni.

330
00:14:42,680 --> 00:14:46,424
Jekk kelli ifformattjat forma tiegħi b'mod differenti,
I jista 'jkollhom it-linja b'linja billi linja.

331
00:14:46,424 --> 00:14:47,590
Imma I ma tagħmel ebda grafika.

332
00:14:47,590 --> 00:14:49,256
Għal darb'oħra, aħna mhux qed jitkellem dwar CSS hawn.

333
00:14:49,256 --> 00:14:51,030
Aħna biss jitkellem dwar HTML.

ftakar li l-forom ta 'test tip

336
00:14:55,480 --> 00:14:57,330
U fl password tiegħi I
tista tip password tiegħi.

337
00:14:57,330 --> 00:14:59,740
U minħabba li qasam
huwa tal password tip,

338
00:14:59,740 --> 00:15:01,470
inti ma tkunx taf liema password tiegħi huwa.

339
00:15:01,470 --> 00:15:02,800
Huwa tikek kollha.

340
00:15:02,800 --> 00:15:09,140
>> I tista 'wkoll jagħżel li immarka off
buttuna tar-radju jew immarka off kaxxa verifika.

Jew I jistgħu jissottomettu l-formola tiegħi.

342
00:15:10,420 --> 00:15:11,810
U jien ma tagħmel xejn,
hekk meta I jissottomettu l-formola tiegħi,

343
00:15:11,810 --> 00:15:13,090
il-paġna biss refreshes.

344
00:15:13,090 --> 00:15:16,970
Imma I tista 'forsi jiġi kkonfigurat tiegħi
Buttuna issottometti li tagħmel xi ħaġa oħra.

345
00:15:16,970 --> 00:15:20,410
U aħna ser tara dak li nistgħu nagħmlu mal
li fil-video futur fuq PHP.

346
00:15:20,410 --> 00:15:22,520
Iżda dan jibni ħafna
formola sempliċi li aħna

00:15:22,520 --> 00:15:27,360
jistgħu jużaw biex ikollhom utenti jinteraġixxu u

tinsab ġewwa l-
tag u l-attributi tagħha.

363
00:16:04,974 --> 00:16:06,390
Allura xi kultant tkun taf tara dan, wisq.

364
00:16:06,390 --> 00:16:10,400
Hekk biss tkun taf li jekk għandek
tag li huwa kompletament self-contained,

365
00:16:10,400 --> 00:16:14,170
tiftaħ u tagħlaq ruħha ma
il-kategorija angolu miftuħ fuq ix-xellug

366
00:16:14,170 --> 00:16:17,000
u l-angolu mmejla

367
00:16:17,000 --> 00:16:20,580
Ser naraw lil xulxin minn dawk

>> Qabel nitkellmu dwar stampi, aħna

interattivi u jgħinuna madwar,

00:16:26,080 --> 00:16:28,121
ikun sbieħ jkunu jistgħu
ikklikkja fuq waħda minn dawk

371
00:16:28,121 --> 00:16:30,190
dak li tipikament kienet link blu.

372
00:16:30,190 --> 00:16:34,440
Dan huwa attwalment kif nistgħu nibnu
hyperlink fil-paġna web tagħna.

373
00:16:34,440 --> 00:16:36,540
U interessanti biżżejjed
hemm tag ieħor HTML

u l-għeluq A tag

378
00:16:51,580 --> 00:16:56,010
huwa dak li għaddej biex tkun li enfasizzat
test blu li tidher qiesha link

379
00:16:56,010 --> 00:16:57,590
li aħna qed familjari magħhom.

380
00:16:57,590 --> 00:17:01,660
Hawn taħt li għandna tag immaġini, li
huwa awto-għeluq tag għall-wiri

381
00:17:01,660 --> 00:17:05,599

386
00:17:16,170 --> 00:17:19,410
Huwa exclamation punt DOCTYPE HTML.

387
00:17:19,410 --> 00:17:23,300
Allura HTML kien madwar peress li l-
1990 għall-bini paġni web,

388
00:17:23,300 --> 00:17:25,859
u marret għaddew minnu
bosta reviżjonijiet minn dakinhar.

389
00:17:25,859 --> 00:17:28,550
Aktar reċentement fl-2014
għadda reviżjoni

390
00:17:28,550 --> 00:17:33,440
imsejħa HTML5 li issa hija l-kurrent
tip ta 'de facto standard HTML.

>> Li jindika li web tagħna
paġni huma miktuba bl-użu HTML5,

393
00:17:38,160 --> 00:17:40,380
Hija tista 'titħalla barra iżda
dak li bażikament

394
00:17:40,380 --> 00:17:45,930
mezzi huwa inti ma tistax tuża kwalunkwe mill-tags
li huma tags HTML5, dawk tikketti ġodda.

395
00:17:45,930 --> 00:17:48,591
Allura aħna dejjem tibda off
jekk aħna qed tuża HTML5.

396
00:17:48,591 --> 00:17:51,340
U l-tags konna tkellimna dwar
qabel mhumiex tags HTML5.

397
00:17:51,340 --> 00:17:55,470
Iżda dan ikun jindika li
Tags HTML5 se jkunu preżenti.

398
00:17:55,470 --> 00:17:58,400
U hekk aħna exclamation
HTML DOCTYPE, li

399
00:17:58,400 --> 00:18:01,280
huwa fil-bidu nett ta 'tagħna
Fajl HTML, u mbagħad wara dak il-punt

400
00:18:01,280 --> 00:18:04,930
għandna attwalment ikollhom HTML tagħna miftuħa

>> L-aħħar wieħed huwa tag kumment,

bracket sing exclamation

sing iżda l-ebda parentesi għeluq.

404
00:18:15,220 --> 00:18:20,150
Fil bejn dawn iż-żewġ elementi hemmhekk
huwa fejn tikteb kummenti tiegħek.

405
00:18:20,150 --> 00:18:28,420

kummenti hawn fil-kummenti HTML tiegħi.

408
00:18:36,420 --> 00:18:38,990
Hekk biss bħal fis-C u oħrajn
lingwi ta 'programmar,

00:18:38,990 --> 00:18:43,169
HTML biss billi jkunu lingwa markup
ma jkollu l-abbiltà li jkollhom kummenti.

410
00:18:43,169 --> 00:18:45,710
U hekk jien apparentement ser

Allura li biss tirreferi għall bonjour dot HTML
