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: <base>, <link>, <meta>,
<title>, <style>, and <script>.
Look at the following illegal construct:
<head>
<p>This is some text</p>
</head>
|
In this case the browser has two options:
- Display the text because it is inside a paragraph
element
- Hide the text because it is inside a head element
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.
Should browsers forgive you for errors like this? We don't
think so. Others do.
