[网页设计]三(奇数)等分两者中间有间隔,两端没间隔


1.三等分

采用box-sizing:border-box;然后分别给他们赋值你想要的百分比,左边和上边加上border或者padding,本实例采用的是padding,因为样式1,样式二总共分为两层所有用百分比更加合适,最后给他们的父元素添加个margin-left:-间隔大小;让左右两边的间隔不会出现大小不一样。

<div class="cards cards-1/2/3">  <ul class="cardlist clearfix">                      <li>      <a href="tuniuapp://travel/discover/new_community/tag_list" style="background-image:url(/image/one.jpeg)"></a>    </li>                                      <li>      <a href="tuniuapp://travel/discover/new_community/group_list" style="background-image:url(/image/one.jpeg)"></a>    </li>                                      <li>      <a href="tuniuapp://travel/discover/new_community/post_detail?post_id=13883" style="background-image:url(/image/one.jpeg)"></a>    </li>                  </ul></div>
