You can achieve the color-changing effect of clicked elements by using css pseudo-classes. The two pseudo-classes are: active, :focus

1, :active: used to select active links. When a link is clicked, it becomes active (activated). The :active selector applies to all elements, not just link a elements

:focus: Used to select the element that has received focus. The :focus selector is only allowed on elements that receive keyboard events or other user input.

Due to the above characteristics, if you want to achieve the effect of changing color when clicked, there are two methods. The difference between the two is

: active. The element changes color when clicked, but the color disappears after clicking.

: focus, the element changes color after being clicked, and the color does not disappear after being clicked

<html> 
<head> 
<meta http-equiv="Content-Type" content="text/html; charset=utf-8" /> 
<title>document</title> 
<style>
    div{
        background: #fff;
        border:1px solid rgb(59, 59, 59);
        border-radius: 5px;
        margin: 10px 0;
    }
    div:focus {
            background-color:red;
        }
</style>
</head> 
<body bgcolor="#ccc">
