SPEAKER: Much like books have headings for chapters and sections and subsections, so do a lot of web pages have headings for the top level information, for secondary information, for tertiary information, and so forth. Well for these, HTML has heading tags, h1, h2, h3, h4, h5, and h6. Let's see these in action in the context of a web page. 

Here in headings.html, I've already gotten things started with some open tags and close tags. Let's now inside the body do h1 and then type something arbitrary, like one. Let's now close this tag. Let's now demonstrate the h2 tag similarly with the text two, the h3 text with three, the h4 text with four, the h5 text with five, and the h6 text with six. 

Let's now save this style, change its permissions, and view it in a browser-- chmod a + r headings.html. Let's open up Chrome, visit http://localhost/headings.html. Now even though I didn't specify any bold facing, let alone any particular font sizes, Chrome has by default rendered h1 as really big and bold, h2 as big and bold, and h3 and h4 and h5 and h6 as bold but not quite as big.
