<p class="intro">HTML documents are text files made up of HTML elements.</p>
<p class="intro">HTML elements are defined using HTML
tags.</p>
<hr />
<h2>HTML Tags</h2>
<ul>
<li>HTML tags are used to mark-up HTML <b> elements</b></li>
<li>HTML tags are surrounded by the <b> two characters < and ></b></li>
<li>The surrounding characters are called <b>angle brackets</b></li>
<li>HTML tags normally <b> come in pairs</b> like <b> and </b></li>
<li>The first tag in a pair is the <b> start tag,</b> the
second tag is the <b> end tag</b></li>
<li>The text between the start and end tags is the <b>element content</b></li>
<li>HTML tags are <b> not case sensitive,</b> <b> means the same as <B></li>
</ul>
<hr />
<h2>HTML Elements</h2>
<p>Remember the HTML example from the previous page:</p>
<table width='100%' border="1" class="ex" cellspacing="0"><tr><td>
<pre><html>
<head>
<title>Title of page</title>
</head>
<body>
This is my first homepage. <b>This text is bold</b>
</body>
</html></pre>
</td></tr></table>
<p>This is an HTML element:</p>
<table width='100%' border="1" class="ex" cellspacing="0"><tr><td>
<pre><b>This text is bold</b></pre>
</td></tr></table>
<p>The HTML element starts with a <b> start tag</b>: <b><br />
The <b> content</b> of the HTML element is: This text is bold<br />
The HTML element ends with an <b> end tag</b>: </b></p>
<p>The purpose of the <b> tag is to define an HTML element that should be displayed as
bold.</p>
<p>This is also an HTML element:</p>
<table width='100%' border="1" class="ex" cellspacing="0"><tr><td>
<pre><body>
This is my first homepage. <b>This text is bold</b>
</body></pre>
</td></tr></table>
<p>This HTML element starts with the start tag <body>, and ends with the
end tag </body>.</p>
<p>The purpose of the <body> tag is to define the HTML element that
contains the body of the HTML document.</p>
<hr />
<h2>Why do We Use Lowercase Tags?</h2>
<p>We have just said that HTML tags are not case sensitive: <B> means the
same as <b>. If you surf the Web, you will notice that plenty of web sites use uppercase HTML tags in their
source code. We
always use lowercase tags. Why?</p>
<p>If you want to follow the latest web standards, you should always use lowercase tags. The World Wide Web Consortium (W3C) recommends lowercase tags in
their HTML 4 recommendation, and XHTML (the next generation HTML) demands
lowercase tags.</p>
