1.1、纯css通过伪元素来定义input输入框激活样式
HTML代码:
<body>
<input type="checkbox" id="myCheck">
<label for="myCheck"></label>
</body>
CSS伪元素实现代码:
#myCheck + label{
background-color: white;
border-radius: 5px;
border:1px solid #d3d3d3;
width:20px;
height:20px;
display: inline-block;
text-align: center;
vertical-align: middle;
line-height: 20px;
}
#myCheck:checked + label{
background-color: #eee;
}
#myCheck:checked + label:after{
content:"\2713";
}
注:
1、加号为相邻兄弟选择器,即选择相邻的下一个兄弟元素
2、content:"\2713"为特殊符号对号的预留字符。值得一提的是html中的为10003和css,js中是不一样的。css和js中是一样的。更多特殊符号见:http://www.haorooms.com/post/html_tsfh
1、2开关样式的checkbox
不多说直接上代码:
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title>纯css编写开关按钮(二)</title>
<style type="text/css">
#toggle-button{ display: none; }
.button-label{
position: relative;
display: inline-block;
width: 80px;
height: 30px;
background-color: #ccc;
box-shadow: #ccc 0px 0px 0px 2px;
border-radius: 30px;
overflow: hidden;
}
.circle{
position: absolute;
top: 0;
left: 0;
width: 30px;
height: 30px;
border-radius: 50%;
background-color: #fff;
}
.button-label .text {
line-height: 30px;
font-size: 18px;
text-shadow: 0 0 2px #ddd;
}
.on { color: #fff; display: none; text-indent: 10px;}
.off { color: #fff; display: inline-block; text-indent: 34px;}
.button-label .circle{
left: 0;
transition: all 0.3s;
}
.btn:checked + label.button-label .circle{
left: 50px;
}
.btn:checked + label.button-label .on{ display: inline-block; }
.btn:checked + label.button-label .off{ display: none; }
.btn:checked + label.button-label{
background-color: #5cb85c;
}
</style>
</head>
<body>
<div class="toggle-button-wrapper">
<input type="checkbox" id="toggle-button1" name="switch" class="btn">
<label for="toggle-button1" class="button-label">
<span class="circle"></span>
<span class="text on">开启</span>
<span class="text off">关闭</span>
</label>
</div>
<div class="toggle-button-wrapper">
<input type="checkbox" id="toggle-button2" name="switch" class="btn">
<label for="toggle-button2" class="button-label">
<span class="circle"></span>
<span class="text on">开启</span>
<span class="text off">关闭</span>
</label>
</div>
</body>
</html>
2、input type=submit设置高度无效的问题
经过测试input submit高度无效是由于在Mac上的Chrome造成的。就是说Mac上的其他浏览器是可以的。Windows上的Chrome也是可以的;解决办法就是给input submit添加背景颜色就可以解决了
