CSS实现栅格布局

设置容器container：

.grid-container {

    width: 100%;

    max-width: 1200px;

}

清除浮动：

.row:before, .row:after {

    content: "";

    display: block;

    height:;

    width:;

    visibility: hidden;

    clear: both;

}

假设有12列布局：

[class*='col_'] {

    float: left;

    min-height: 1px;

    width: 8.33%;

    box-sizing: border-box;

    -moz-box-sizing: border-box;

    -o-box-sizing: border-box;

    -ms-box-sizing: border-box;

    -webkit-box-sizing: border-box;

}

.col_1 { width: 8.33%; }

.col_2 { width: 16.66%; }

.col_3 { width: 25%; }

.col_4 { width: 33.33%; }

.col_5 { width: 41.66%; }

.col_6 { width: 50%; }

.col_7 { width: 58.33%; }

.col_8 { width: 66.66%; }

.col_9 { width: 75%; }

.col_10 { width: 83.33%; }

.col_11 { width: 91.66%; }

.col_12 { width: 100%; }
