HTMLHTMLInternet Basics & Beyond
What The HeckIs HTML?
• HTML is the language of web pages.
• In order to truly understand HTML, you need to know a little about browsers, and in order to understand browsers, you really need to know a little about how the web works.
Let's Start At The Beginning...
• The World Wide Web is a huge collection of computers which are linked together in a network.
• Data, or information, is stored on every computer on the internet, and takes many forms.
• Spreadsheets are a form of data, as are Word documents, images, sound bites, and web pages.
Web pages are encoded…
• Web pages are encoded. • The encoding process isn't difficult, and is
usually done by hand. • The way pages are encoded is with a MARK-
UP language we call HTML.• Remember that web pages are usually used as
a means of conveying data, or information. • The data is your message. This is the meat of
the HTML document. • Text and content are most important.
What happens next?
• Once you have created a web page, you store it on a certain type of computer called a web server.
• Web servers are computers which are attached to the Internet, and do basically two things.
• A web server stores information documents and sends those documents to any other computer which requests them.
What's Really Going on?
• You attach to the Internet with a special type of computer program known as a browser.
• The first thing the browser wants to know is where to go.
• You type in an URL or uniform resource locator. – An URL is an address. This address tells the
browser exactly where to find the page you're looking for.
Cue The Browser
• The browser takes all that raw data, and translates it.
• Then displays it on your screen. what the browser sees is raw data, which might look like this:
<img src="http://DIS.DOZIER.COM/logo.gif">
• But what you see is the browsers interpretation of that data.
Hypertext Markup
Language • A webpage is simply a text file ending
with the suffix .html or .htm.
• It is created using MS NOTEPAD.
• This text file is often referred to as the "source code" of a webpage.
<> It's All In The Angles
• HTML tags are easy to recognize because they are always between a lesser than sign and greater than sign, or as I like to call them, Angle Brackets.

Parts Is Parts
• Every web page written in HTML has essentially two parts:
The Head The Body
• Now, having told you that, let me tell you about one more tag before going on.
<HTML> </HTML>
• The HTML tag tells your computer that everything between these two tags is an HTML document.
• You'll always begin your page with the opening HTML tag and end it with the closing HTML tag.
<HEAD> </HEAD>
The Skeleton
• Here is the HTML for a VERY simple webpage.
<HTML><HEAD><TITLE> THE COOLEST PAGE ON THE WEB </TITLE></HEAD><BODY>Whoa!!! This is so TOTALLY cool. </BODY></HTML>
• See how these tags fit into each other? And how all the text is between the BODY tags?
