<h1>HTML Head</h1>
<a href="html_styles.asp"><img border="0" src="../images/btn_previous.gif" width="100" height="20" alt="Previous" /></a>
<a href="html_meta.asp"><img border="0" src="../images/btn_next.gif" width="100" height="20" alt="Next" /></a>

<h2>Examples</h2>
<p><a target="_blank" href="tryit.asp@filename=tryhtml_title">The title of a document</a><br />
The title information inside a head element is not displayed in the browser
window.</p>
<p><a target="_blank" href="tryit.asp@filename=tryhtml_base">One target for all links</a><br />
This example demonstrates how to use the base tag to let all the links on a page
open in a new window.</p>
<hr />
<h2>The Head Element
</h2>
<p>The head element contains general information, also called meta-information, about
a document. Meta means "information about".
</p>
<p>You can say that meta-data means information about data, or meta-information means information about information.
</p>
<hr />
<h2>Information Inside the Head Element
</h2>
<p>
The elements inside the head element should not be displayed by a browser.
</p>
<p>
According to
the HTML standard, only a few tags are legal inside the head
section. These are: <base>, <link>, <meta>, <title>, <style>,
and <script>.
</p>
<p>Look at the following illegal construct:
</p>
<table border="1" width="100%" class="ex" cellspacing="0">
<tr>
<td>
<pre><head>
<p>This is some text</p>
</head></pre>
</td>
</tr>
</table>
<p>In this case the browser has two options:</p>
<ul>
<li>Display the text because it is inside a paragraph element</li>
<li>Hide the text because it is inside a head element</li>
</ul>
<p>If you put an HTML element like <h1> or <p> inside a head element
like this, most browsers will display it, even if it is illegal.</p>
<p>Should browsers forgive you for errors like this? We don't think so. Others
do.</p>
