Class is called "class" in the program, and it is also called "class" in written language in CSS. In the CSS style, use lowercase "dot" and "." to name it such as: .top{attribute: attribute value;}.

In the html page, use class="top" to select the call, such as: .top{attribute: attribute value;}, in the html page, call it as
example is as follows:
<!DOCTYPE html>
<html>
<head>
<style>
.intro
{
background-color:yellow;
}
</style>
</head>
<body>
