What is used to connect class in css3
.class selector selects elements with a specified class (class).
Class selectors allow styles to be specified in a way that is independent of document elements.
This selector can be used alone or in combination with other elements.
Tip: These selectors can only be used after the document has been properly marked up, so using either selector usually requires some thought and planning.
To apply styles regardless of the specific design element, the most common way is to use a class selector.
The .class selector specifies the style of all elements of the class.
The example is as follows:
<html>
<head>
<style>
.intro
{
background-color:yellow;
}
</style>
</head>
<body>
<h1 id="Welcome-nbsp-to-nbsp-My-nbsp-Homepage">Welcome to My Homepage</h1>
<div class="intro">
<p>My name is Donald.</p>
<p>I live in Duckburg.</p>
</div>
<p>My best friend is Mickey.</p>
</body>
</html>Output result:
