Chapter 5
The id and class Selectors
In addition to setting a style for a HTML element, CSS allows you
to specify your own selectors called "id" and "class".
The id Selector
The id selector is used to specify a style for a single, unique
element.
The id selector uses the id attribute of the HTML element, and is
defined with a "#".
The style rule below will be applied to the element with
id="para1":
Example :3
<!By using ID >
<html>
<head>
<style>
#para1
{
text-align:center;
color:red;
}
</style>
</head>
<body>
<p id="para1">Hello World!</p>
<p>This paragraph is not affected by the style.</p>
</body>
</html>
Output is:
Hello World!
This paragraph is not affected by the style.
