好久在这里写文章了,
谈谈bfc吧。概念什么的就不说了。
很简单的一个东西,在布局的时候确实真的很有用处的。

margin: 0 auto;
font-family: Arial;
background: red;
-webkit-background-size: cover;
background-size: cover;
color: #fff;
}
h1 { text-align: center; }
.bfc { height: 30px; line-height: 30px; font-family: "Tahoma"; margin: 0 10px; padding: 10px 0; }
.bfc:before,
.bfc:after { content: "."; display: table; visibility: hidden; font-size: 0; height: 0; line-height: 0; }
.bfc .name { float: left; font-size: 12px; font-weight: 700; padding-right: 15px; }
.bfc .line { height: 1px; font-size: 0; background-color: #fff; position: relative; top: 15px; overflow: hidden; }
.bfc .page { float: right; margin-left: 15px; }
这种就是简单的目录排版结构,实现的方法有很多,但是这样实现的话可拓展性比较高,
还有就是输入验证码的时候还剩下多少秒的布局,其实用这个也是有很多好处的,还可以增加icon。以便后期维护
