What is HTML?

In the same way that proofreader marks help editors format an essay, HTML tells browsers how to format your page

09.16.09

HTML vs. CSS HTML for content (think of a scaffold), CSS

for presentation (color, fonts, advanced layout)

Many HTML elements and attributes declaring colors, fonts, background, etc. are deprecated

Deprecated means the code will not be (or is not) supported by the most recent versions of HTML and web browsers

What is a Web Browser? A web browser is a computer application that

does two things: It goes to a web server on the internet and

requests a page, so it can pull the page through the network and into your machine

It interprets the HTML elements and tags within the page in order to display it on the screen as the page’s creator intended
