```
.clearfloat{
    zoom:1;
}
.clearfloat:after{
    clear: both;
    content: '.';
    display: block;
    width: 0;
    height: 0;
    visibility: hidden;
}
```
把重置样式改成上面的那样，就不会出现问题了。
原因就是由于子元素都用了浮动，而父级元素需要用它的子元素来实现高度自适应，不然如果父级元素没有高度或者内容，子级元素的排版就不受父级元素的控制。
添加了一个句号content:"."，并且把它的display设置成block；高度设为0；clear设为both；visibility设为隐藏。这样父级元素有了一个"."的内容，就达到了撑开容器的目的。

我也是出这种问题了，怎么解决的？重置样式哪错了？
