CSS content property not displaying
I am new to CSS and I'm following a book example:
Iv'e copied the following from the book and saved it as HTML. all the css properties seem to work except the "content" property which does not display.Thanks in advance.
<!DO开发者_如何转开发CTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN"
"http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd">
<html>
<head>
<title> The content property </title>
<style type='text/css' media='all'>
div {
content: "Hello, world!";
}
</style>
</head>
<body>
<div></div>
</body>
</html>
content is used with :before or :after like so:
div:after
{
content: "Hello, world!";
}
Regardless, I've only used content for special cases (to clear floated elements, for example). I've never actually used this to insert content. You generally want to separate content and presentation anyway, so I think this is a bad idea. Which book are you reading? :)
The content property only applies to CSS pseudo-elements such as :before and :after.
You cannot use it to set the content of an arbitrary element.
The content property only works for :before and :after to prepend or append content to said nodes, like so:
.email-address:before {
content : "Email address: ";
}<ul>
<li class="email-address">myemail@gmail.com</li>
</ul>The output would be
• Email address: myemail@gmail.com
