CSS边框长度控制
以前需要边框长度比容器小一些时,我用div嵌套。后来发现伪类在实现这个效果时很方便,只需要一个div就够了,另外调整padding和margin都不会很麻烦。
<div class="content-block"><div class="box-container"><div class="border-top">border top</div></div><div class="box-container"><div class="border-left">border left</div></div><div class="box-container"><div class="border-right">border right</div></div><div class="box-container"><div class="border-bottom">border bottom</div></div></div>
.box-container {position: relative;width: 90%;color: #777;}.border-top {background: #b4bcbf;padding: 15px;}.border-top:before {content: '';position: absolute;left: 42%;top: 0;bottom: auto;right: auto;height: 7px;width: 50%;background-color: #8796a9;}.border-left {background: #dfdad6;padding: 15px;}.border-left:before {content: '';position: absolute;left: 0;top: 6%;bottom: auto;right: auto;height: 52%;width: 5px;background-color: #a89d9e;}.border-right {background: #eee9c4;padding: 15px;}.border-right:after {content: '';position: absolute;left: auto;top: auto;bottom: 5px;right: 0;height: 52%;width: 5px;background-color: #f39c81;}.border-bottom {background: #bcdc9d;padding: 15px;}.border-bottom:after {content: '';position: absolute;left: 18px;top: auto;bottom: 0;right: auto;height: 6px;width: 105px;background-color: #32b66b;}
效果如下图:
食用愉快~
