    border:none;
    border-radius:10px;
    width:790px;
    padding:10px;
    margin: 0 0 0 10px;

Answer 1

你可以使用：after伪元素和内容，如下所示：

input#checkbox-1:checked + label {
    visibility: hidden;
    position: relative;
}

input#checkbox-1:checked + label:after {
    visibility: visible;
    position: absolute;
    left: 0;
    top: 0;
    content: "Close";
}

虽然没有额外的标记，但这不适用于IE。您需要在标签内放置一个元素并使用CSS

隐藏它

<input type="checkbox" id="checkbox-2" name="checkbox-accordion" />
<label for="checkbox" style="text-align:right;"><span>Click for details</span></label>

input#checkbox-2:checked + label span {
    display: none;
}

input#checkbox-2:checked + label:after {
    content: "Close";
}

请参阅http://jsfiddle.net/r292puep/3/了解演示

Answer 2

只需在标签内使用几个跨度，并根据是否选中该复选框显示它们

#checkbox-1:checked + label > .on{
    display: inline;
}

#checkbox-1:checked + label > .off,
#checkbox-1 + label > .on {
    display: none;
}

<input type="checkbox" id="checkbox-1" name="checkbox-accordion" />
<label for="checkbox" style="text-align:right;"><span class="on">I'm ON</span><span class="off">I'm OFF</span></label>

点击更改标签文字？
