<h2>What is CSS?</h2>

<ul>
  <li><b>CSS</b> stands for <b>C</b>ascading <b>S</b>tyle <b>S</b>heets</li>
  <li>Styles define <b> how to display</b> HTML elements</li>
  <li>Styles are normally stored in <b>Style Sheets</b> </li>
  <li>Styles were added to HTML 4 <b>to solve a problem</b></li>
  <li><b>External Style Sheets</b> can save you a lot of work</li>
  <li>External Style Sheets are stored in <b>CSS files</b></li>
  <li>Internal and external style sheets will <b>Cascade</b> into one</li>
</ul>

<hr />
<h2>CSS Demo</h2>
<p>With CSS, your HTML documents can be displayed using different output styles:</p>
<p> <a href="../css/demo_default.htm" target="_blank">See how it works</a></p>
<hr />
<h2>Styles Solve a Common Problem</h2>
<p>HTML tags were originally designed to define the content of a document. They
were supposed to say &quot;This is a header&quot;, &quot;This is a
paragraph&quot;, &quot;This is a table&quot;, by using tags like &lt;h1&gt;,
&lt;p&gt;, &lt;table&gt;, and so on. The layout of the document was supposed to
be taken care of by the browser, without using any formatting tags.</p>
<p>As the two major browsers - Netscape and Internet Explorer -
continued to add new HTML tags and attributes (like the &lt;font&gt; tag and the
color attribute) to the original HTML specification, it became
more and more difficult to create Web sites where the content of HTML
documents was clearly separated from the document's presentation
layout.</p>
<p>To solve this problem, the World Wide Web Consortium (W3C) - the non profit,
standard setting consortium, responsible for standardizing HTML - created STYLES
in addition to HTML 4.0.&nbsp;&nbsp;</p>
<p>
All major browsers support Cascading Style Sheets.</p>
<hr />
<h2>Style Sheets Can Save a Lot of Work</h2>
<p>Styles sheets define HOW HTML elements are to be displayed, just like the
font tag and the color attribute in HTML 3.2. Styles are normally saved in 
external .css files. External style sheets enable you to change the
appearance and layout
of all the pages in your Web, just
by editing one single CSS document!</p>
<p>CSS is a breakthrough in Web design
because it allows developers to control the style and layout of multiple Web pages all at once.
As a Web developer you can define a style for each HTML element and apply it to as 
many Web pages as you want. To make a global change, simply
change the style, and all elements in the Web are updated automatically.</p>
