如何使用CSS选择具有指定属性和值的元素
使用[attribute=“value”]选择器选择具有指定属性和值的元素。
您可以尝试运行以下代码来实现CSS[attribute=“value”]选择器。在这里，我们将属性视为rel，
例：
<!DOCTYPE html>
<html>
<head>
<style>
a[rel = nofollow] {
border: 3px solid blue;
}
</style>
</head>
<body>
<a href = "https://qries.com/What-is-Uber-s-business-model-and-how-does-it-compare-with-Ola-s-model-in-India" rel = "nofollow">Uber's Business Model</a><br><br>
<a href = "https://www.qries.com/How-does-share-market-work-in-India" rel = "noreferrer">Share Market</a>
</body>
