CSS pseudo-classes are used to add special effects to some selectors.
Syntax
The syntax of pseudo-classes:
selector:pseudo-class {
property:value;
}
property:value;
}
selector.class:pseudo-class {
property:value;
}
property:value;
}
Anchor Pseudo-classes
Links can be displayed in different ways in a CSS-supporting browser:Example
/* unvisited link */
a:link {
color: #FF0000;
}
/* visited link */
a:visited {
color: #00FF00;
}
/* mouse over link */
a:hover {
color: #FF00FF;
}
/* selected link */
a:active {
color: #0000FF;
}
a:link {
color: #FF0000;
}
/* visited link */
a:visited {
color: #00FF00;
}
/* mouse over link */
a:hover {
color: #FF00FF;
}
/* selected link */
a:active {
color: #0000FF;
}

| Note: a:hover MUST come after a:link and a:visited in the CSS definition in order to be effective!! a:active MUST come after a:hover in the CSS definition in order to be effective!! Pseudo-class names are not case-sensitive. |
Pseudo-classes and CSS Classes
Pseudo-classes can be combined with CSS classes:CSS - The :first-child Pseudo-class
The :first-child pseudo-class matches a specified element that is the first child of another element.| Note: For :first-child to work in IE8 and earlier, a <!DOCTYPE> must be declared. |
Match the first <p> element
In the following example, the selector matches any <p> element that is the first child of any element:Example
<html>
<head>
<style>
p:first-child {
color: blue;
}
</style>
</head>
<body>
<p>I am a strong man.</p>
<p>I am a strong man.</p>
</body>
</html>
<head>
<style>
p:first-child {
color: blue;
}
</style>
</head>
<body>
<p>I am a strong man.</p>
<p>I am a strong man.</p>

CSS - The :lang Pseudo-class
The :lang pseudo-class allows you to define special rules for different languages.| Note: IE8 supports the :lang pseudo-class only if a <!DOCTYPE> is specified. |
Example
<html>
<head>
<style>
q:lang(no) {
quotes: "~" "~";
}
</style>
</head>
<body>
<p>Some text <q lang="no">A quote in a paragraph</q> Some text.</p>
</body>
</html>
<head>
<style>
q:lang(no) {
quotes: "~" "~";
}
</style>
</head>
<body>
<p>Some text <q lang="no">A quote in a paragraph</q> Some text.</p>
</body>
</html>
