HTML Head The Head Element The head element contains general information, also called meta-information, about a document. Meta means "information about".
You can say that meta-data means information about data, or meta-information means information about information.
Information Inside the Head Element The elements inside the head element should not be displayed by a browser.
According to the HTML standard, only a few tags are legal inside the head section. These are:
, <style>, and <script>. </p> <p>Look at the following illegal construct: </p> <table class="ex" border="1" cellspacing="0" width="100%"> <tbody><tr> <td> <pre><head><br /> <p>This is some text</p><br /></head></pre> </td> </tr> </tbody></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> <hr /> <h2>Head Tags</h2> <table class="ex" border="1" cellspacing="0" width="100%"> <tbody><tr> <th align="left" valign="top" width="25%">Tag</th> <th align="left" valign="top" width="80%">Description</th> </tr> <tr> <td valign="top"><head></td> <td valign="top"> Defines information about the document</td> </tr> <tr> <td valign="top"><title></td> <td valign="top">Defines the document title</td> </tr> <tr> <td valign="top"><base></td> <td valign="top">Defines a base URL for all the links on a page</td> </tr> <tr> <td valign="top"><link></td> <td valign="top">Defines a resource reference</td> </tr> <tr> <td valign="top"><meta></td> <td valign="top">Defines meta information</td> </tr> </tbody></table><br /> <table class="ex" border="1" cellspacing="0" width="100%"> <tbody><tr> <th align="left" valign="top" width="25%">Tag</th> <th align="left" valign="top" width="80%">Description</th> </tr> <tr> <td valign="top" width="80"><!DOCTYPE></td> <td valign="top">Defines the document type.
