SPEAKER: How about a list? Say, a list of all of the houses in Harvard's Quad? Well, let's start a file called list.html and go ahead and declare initially an ordered list of houses. 

Here, I've already gotten us started in list.html with some open tags and some close tags. Let's now introduce open bracket OL close bracket for Ordered List. And now, because I'm going to have a few things inside of this, let's preemptively close this tag so I don't forget to do so later. 

And inside of this open and close tag let's now put a list item, abbreviated LI, inside of angled brackets. Let's now do, say, Cabot, and then close this list item. Let's then in another list item do Currier and close that list item as well. And then lastly, let's start another list item and do Pforzheimer, and close that list item as well. 

Let's now save this file, change its permissions, and do it in a browser. Chmod a plus r list.html. Let's now open up Chrome, visit http://localhost/list.html. There's our list. 

And notice that the browser, because I specified an ordered list, or OL, has numbered these items for me. Suppose though, that, the numbers aren't all that desirable and I instead just want a more typical bulleted list. I don't want an ordered list, therefore. I want an unordered list. 

Well, this is an easy change. Let's go back to gedit and change the OL to UL both in the start tag and in the end tag. Let's now re-save the file. I don't need to re-change the permissions because simply changing the file does not change its permissions. We did that already before. But now let's reload this same page in Chrome. 

Back in Chrome, we'll click this icon, or Control-R. And now my one, two, and three have become instead three bullets.
