 <div class="shipping-addr-more">

     <a class="addr-more-btn up-down-btn" href="#">

         more<!--利用css3样式旋转，使箭头变化-->

         <i class="i-up-down">

             <i class="i-up-down-l"></i>

             <i class="i-up-down-r"></i>

         </i>

     </a>

 </div>

 </body>

主要是利用css3的transform的旋转变化来修改

其中transtion语法：

transition: property duration timing-function delay;
transition:  过渡效果的 CSS 属性的名称  渡效果需要多少秒或毫秒  过渡效果何时开始

ease    规定慢速开始，然后变快，然后慢速结束的过渡效果（cubic-bezier(0.25,0.1,0.25,1)）。

ease-in    规定以慢速开始的过渡效果（等于 cubic-bezier(0.42,0,1,1)）。

ease-out    规定以慢速结束的过渡效果（等于 cubic-bezier(0,0,0.58,1)）。

ease-in-out    规定以慢速开始和结束的过渡效果（等于 cubic-bezier(0.42,0,0.58,1)）。
