a span之类默认都是inline .width属性对他们无效

有时候需要对他们指定width,将他们display=inline-block即可

.clearfix:after {content:"\200B"; display:block; height:0; clear:both; }
.clearfix { *zoom:1; }

如，实现son在father的正中间(垂直方向上)

.html

<div class="father">
    <div class="son"></div>
</div>

.css

.father {
    position: relative;
    height: 40px;
}
.son {
    position: absolute;
    height: 24px;
    top: 50%;
    margin-top: -12px;
}
