checkbox多选

最近写了一个适合移动端的checkbox，如图：

ps：中间的勾勾是iconfont，iOS风格的。

具体的HTML：

<p class="mui-checkbox-con">
 <label>
 <input class="mui-checkbox" type="checkbox">默认未选中</label>
</p>
<p class="mui-checkbox-con">
 <label>
 <input class="mui-checkbox" type="checkbox" checked>默认选中</label>
</p>
<p class="mui-checkbox-con">
 <label>
 <input class="mui-checkbox checkbox-orange" type="checkbox" checked>橘黄色 checkbox-orange</label>
</p>
<p class="mui-checkbox-con">
 <label>
 <input class="mui-checkbox checkbox-green" type="checkbox" checked>绿色 checkbox-green</label>
</p>
<p class="mui-checkbox-con">
 <label>
 <input class="mui-checkbox" type="checkbox" disabled>禁用</label>
</p>

CSS代码（SCSS导出的，排版有些奇怪）：

 transition: background-color ease $duration/2;

带switch开关
本身我做这一个ui的目的是支持移动端的页面，而webkit上也正好支持单标记的input元素是使用伪类（:before或:after），所以我没做更多的支持和优化，我只是想尽量的保持html干净，所以没用其他元素做模拟。如果你要使用在桌面应用上，或支持其他浏览器，可以自己稍微修改一下，反正我是没测试过。

今天继续分享一个iOS风格的switch开关按钮，样子也非常常见，如图：

主要是使用了<input type="checkbox">来模拟实现，具体的HTML：

<label><input class="mui-switch" type="checkbox"> 默认未选中</label>
<label><input class="mui-switch" type="checkbox" checked> 默认选中</label>
<label><input class="mui-switch mui-switch-animbg" type="checkbox"> 默认未选中,简单的背景过渡效果,加mui-switch-animbg类即可</label>
<label><input class="mui-switch mui-switch-animbg" type="checkbox" checked> 默认选中</label>
<label><input class="mui-switch mui-switch-anim" type="checkbox"> 默认未选中，过渡效果，加 mui-switch-anim 
类即可</label>
<label><input class="mui-switch mui-switch-anim" type="checkbox" checked> 默认选中</label>

在实际的使用中后来又增加了两个过渡效果，分别加 mui-switch-animbg和mui-switch-anim 类即可，具体效果查看下面的demo页面。
