我想制作一个在悬停时显示背景颜色的按钮，在按钮按下时显示没有背景颜色的按钮颜色.这是我当前的代码:

I want to make a button that displays a background color when hovering and a button color without a background color when the button is down. Here is my current code:

.windowButton:hover {
    background-color:#1a82b8;
}
.windowButton:active #windowClose polygon {
    fill:#1a82b8;
}

上面代码的问题是它在 :active 时将图标变成了一种颜色，但没有删除 :hover 设置的背景颜色.如何去除背景色?

The problem with the above code is that it turns the icon a color when :active but doesn't remove the background color set by :hover. How do I remove the background color?

推荐答案

你必须在 :hover state 上设置一个新的背景颜色

You have to set a new background color on :hover state

.windowButton:hover {
    background-color:#1a82b8;
}
.windowButton:active {
   fill:#1a82b8;
   background-color:#000000;/*You can put the color you want*/
}

伪状态继承值.出于一致性目的，最好只在伪状态规则中声明您正在更改的样式.

Pseudo states inherit values. For consistency purposes, it is best to only declare the styles which you are changing in your pseudo state rules.

注意: :hover 必须在 :link 和 :visited(如果它们存在)之后CSS定义，为了有效！

Note: :hover MUST come after :link and :visited (if they are present) in the CSS definition, in order to be effective!
