用CSS3实现瀑布流布局

以前使用瀑布流都要用js，现在有了css3，可以轻松实现了。

掌握点：

1、column-count 把div中的文本分为多少列

2、column-width 规定列宽

3、column-gap 规定列间隙

4、break-inside: avoid; 避免元素内部断行并产生新列

注意: Internet Explorer 9及更早 IE 版本浏览器不支持 column-count 属性。

实例：

<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <title>CSS3瀑布流</title>
    <style>
    /*大层*/
    .container{width:80%;margin: 0 auto;}
    /*瀑布流层*/
    .waterfall{
        -moz-column-count:4; /* Firefox */
        -webkit-column-count:4; /* Safari 和 Chrome */
        column-count:4;
        -moz-column-gap: 1em;
      -webkit-column-gap: 1em;
      column-gap: 1em;
    }
    /*一个内容层*/
    .item{
      padding: 1em;
      margin: 0 0 1em 0;
      -moz-page-break-inside: avoid;
      -webkit-column-break-inside: avoid;
      break-inside: avoid;
     border: 1px solid #000;
    }
    .item img{
        width: 100%;
        margin-bottom:10px;
    }
    </style>
