单击时如何更改按钮的背景颜色?

I researched a lot, and I found this JSFiddle looks like what I need, but, when I click the button, the page background is changing. I want the button's color to be changed when clicked, instead.

我研究了很多，我发现这个JSFiddle看起来就是我需要的，但是当我点击按钮时，页面的背景就会发生变化。我希望按钮的颜色在点击时被改变。

div{
    width: 100%;
    height: 100%;
    background: #5CB85C;
    position: absolute;
    top: 0;
    left: 0;
    z-index:1;
}
label.btn {
    position: absolute;
    top:10px;
    left: 10px;
    z-index:2;
    -webkit-touch-callout: none;
    -webkit-user-select: none;
    -khtml-user-select: none;
    -moz-user-select: none;
    -ms-user-select: none;
    user-select: none;
}
input[type="checkbox"]{
    display: none;
}
input[type="checkbox"]:checked + div{
    background: #5BC0DE;
}
label + input[type="checkbox"]:checked{
    background: #000;
}

<link href="http://netdna.bootstrapcdn.com/twitter-bootstrap/2.3.2/css/bootstrap-combined.min.css" rel="stylesheet"/>
<label for="check" class="btn btn-default">Toggle background colour</label>
<input type="checkbox" id="check" />
<div></div>

This is fairly trivial. Simply move the "button" label element to after the checkbox so that you can select it with the + selector (this is called the adjacent sibling selector; there is no previous sibling selector, unfortunately), and change the CSS to match. JSFiddle

这是相当简单的。只需将“按钮”标签元素移动到复选框之后，以便您可以使用+选择器选择它(这称为相邻的兄弟选择器;不幸的是，之前没有兄弟选择器)，并将CSS更改为匹配。JSFiddle

div{
    width: 100%;
    height: 100%;
    background: #5CB85C;
    position: absolute;
    top: 0;
    left: 0;
    z-index:1;
}
.btn {
    position: absolute;
    top:10px;
    left: 10px;
    z-index:2;
    -webkit-touch-callout: none;
    -webkit-user-select: none;
    -khtml-user-select: none;
    -moz-user-select: none;
    -ms-user-select: none;
    user-select: none;
}
input[type="checkbox"]{
    display: none;
}
input[type="checkbox"]:checked + .btn {
    background: #5BC0DE;
}
/* label + input[type="checkbox"]:checked{
    background: #000;
} */ /* I've commented this last selector out as it is unused per Harry's point in the comments */

<link href="http://netdna.bootstrapcdn.com/twitter-bootstrap/2.3.2/css/bootstrap-combined.min.css" rel="stylesheet"/>
<input type="checkbox" id="check" />
<label for="check" class="btn btn-default">Toggle background color</label>
<div></div>

To achieve what you want, in your css use background-color when the button is clicked.

要实现您想要的效果，在css中单击按钮时使用背景色。

":active" property is used for displaying clicked event style...

“:active”属性用于显示单击事件样式……

HTML:

HTML:

<input type='button' class='btn' value='test'/>

CSS:

CSS:

.btn {
    background-color:#00ff00;
}

.btn:active {
    background-color:#ff00ff;
}

Try using css pseudo code:

尝试使用css伪代码:

#check {
  display: none;
}
#check + label.btn {
  cursor: pointer;
  border: 1px solid grey;
  padding: 6px 8px;
  background: ghostwhite;
  border-radius: 7px;
  box-shadow: 0px 1px 1px;
}
#check:checked + label.btn {
  background: wheat;
}
#check + label.btn:hover {
  box-shadow: 0px 3px 2px;
}
#check + label.btn:active {
  box-shadow: 0px 1px 1px inset;
}

<input type="checkbox" id="check" />
<label for="check" class="btn">Toggle background colour</label>

In css you can not go backward you should go forward like following.
You need to put label after input box.

在css中，你不能后退，你应该像下面这样向前走。你需要在输入框后加上标签。

+ is for the next sibling. There is no "previous sibling" selector.

+代表下一个兄弟姐妹。没有“先前的兄弟”选择器。

div{
    width: 100%;
    height: 100%;
    background: #5CB85C;
    position: absolute;
    top: 0;
    left: 0;
    z-index:1;
}
label.btn {
    position: absolute;
    top:10px;
    left: 10px;
    z-index:2;
    -webkit-touch-callout: none;
    -webkit-user-select: none;
    -khtml-user-select: none;
    -moz-user-select: none;
    -ms-user-select: none;
    user-select: none;
}
input[type="checkbox"]{
    display: none;
}
input[type="checkbox"]:checked + label{
    background: #5BC0DE;
}
label + input[type="checkbox"]:checked{
    background: #000;
}

<link href="http://netdna.bootstrapcdn.com/twitter-bootstrap/2.3.2/css/bootstrap-combined.min.css" rel="stylesheet"/>
<input type="checkbox" id="check" />
<label for="check" class="btn btn-default">Toggle background colour</label>
