CSS - Pseudo-class :first-child
Description
The :first-child pseudo-class is used to add special effect to an element that is the first child of some other element.
To make :first-child work in IE <!DOCTYPE> must be declared at the top of document.
Please note that −
Pseudo-class names are not case-sensitive.
Pseudo-class are different from CSS classes but they can be combined.
Example
For example, to indent the first paragraph of all <div> elements, you could use this definition −
<html>
<head>
<style type = "text/css">
div > p:first-child {
text-indent: 25px;
}
</style>
</head>
<body>
<div>
<p>First paragraph in div. This paragraph will be indented</p>
<p>Second paragraph in div. This paragraph will not be indented</p>
</div>
<p>But it will not match the paragraph in this HTML:</p>
<div>
<h3>Heading</h3>
<p>The first paragraph inside the div.This paragraph will not be effected.</p>
</div>
</body>
</html>
This will produce following result −
