我制作了一个悬停时显示文本的按钮，但我希望在用户单击该按钮时显示文本，并在用户再次单击该按钮时消失。该代码基本上是一个按钮和文本，在设置为 0.80 不透明度的黑框中显示“HELLO”。有什么建议吗？

最佳答案
当我理解你的问题是正确的，你想要一个按钮，当用户点击它时悬停是不同的？
您可以通过向按钮添加一个类来实现这一点，该类处理单击的 CSS。
$('button').on('click', function () {
$(this).addClass('clicked');
});
还有CSS
button { background: red; }
button:hover { background: green; }
button.clicked { background: orange; }
button.clicked:hover { background: black; }
关于html - 将悬停更改为 CSS 到 OnClick，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/20355609/
