CSS效果：这里有你想要的CSS3漂亮的自定义Checkbox各种复选框

在原来有一篇文章写到了《CSS效果篇--纯CSS+HTML实现checkbox的思路与实例》。

今天这篇文章主要写各种自定义的checkbox复选框，实现如图所示的复选框：

大致的html代码都如下所示：

<div class="ondisplay">
  <section title=".slideOne">
    <div class="slideOne">  
      <input type="checkbox" value="None" id="slideOne" name="check" checked />
      <label for="slideOne"></label>
    </div>
  </section>
</div>

那么对应的css代码：

body {
  background: #555;
  font-family: 'Open Sans', sans-serif;
  font-weight: 300;
}
body h1, body h2 {
  color: #eee;
  font-size: 30px;
  text-align: center;
  margin: 20px 0 50px 0;
  -webkit-font-smoothing: antialiased;
  text-shadow: 0px 1px black;
}
body .ondisplay {
  text-align: center;
  border-bottom: 1px solid gray;
  padding: 20px 0;
}
body .ondisplay section {
  width: 100px;
  height: 100px;
  background: #555;
  display: inline-block;
  position: relative;
  text-align: center;
  margin-top: 5px;
  border: 1px solid gray;
  -moz-border-radius: 5px;
  -webkit-border-radius: 5px;
  border-radius: 5px;
  -moz-box-shadow: 0 1px 4px rgba(0, 0, 0, 0.3), 0 0 40px rgba(0, 0, 0, 0.1) inset;
  -webkit-box-shadow: 0 1px 4px rgba(0, 0, 0, 0.3), 0 0 40px rgba(0, 0, 0, 0.1) inset;
  box-shadow: 0 1px 4px rgba(0, 0, 0, 0.3), 0 0 40px rgba(0, 0, 0, 0.1) inset;
}
body .ondisplay section:before {
  content: 'click it';
  color: #bbb;
  font-size: 12px;
  font-weight: 400;
  -webkit-font-smoothing: antialiased;
  text-shadow: 0px 1px black;
}
body .ondisplay section:after {
  content: attr(title);
  position: absolute;
  width: 100%;
  left: 0;
  bottom: 3px;
  color: #fff;
  font-size: 12px;
  font-weight: 400;
  -webkit-font-smoothing: antialiased;
  text-shadow: 0px 1px black;
}

      <label for="slideOne"></label>
    </div>
    <!-- end .slideOne -->
  </section>

css代码：

/* .slideOne */
.slideOne {
  width: 50px;
  height: 10px;
  background: #333;
  margin: 20px auto;
  position: relative;
  -moz-border-radius: 50px;
