CSS |:不是选择器

原文:https://www.geeksforgeeks.org/css-not-selector/

:not(选择器)选择器用于设置选择器未指定的每个元素的样式。因为它阻止特定项目被选中，所以也被称为否定伪类。

语法:

:not(selector) {
  //CSS Property
}

示例-1:

<!DOCTYPE html>
<html>

<head>
    <title>
        CSS :not selector
    </title>
    <style>
        p {
            color: #000000;
        }

        :not(p) {
            color: green;
        }
    </style>
</head>

<body style="text-align: center;">

    <h1>

    </h1>

    <p>
        A computer science portal for geeks.
