}

.col {

    margin-left: 0;
    float: left;
}

.col:第一个孩子 {

    margin-left: 0;
}

.footer {

    width: 33%;
    *width: expression(Math.floor(0.33 * (this.parentNode.offsetWidth - parseFloat(this.parentNode.currentStyle.paddingLeft) - parseFloat(this.parentNode.currentStyle.paddingRight))) + "px");
}

.footer-left {

    background-color: red;
    height: 100% !important;
    min-height: 100% !important;
}

.footer {

    background-color: red;
    height: 100% !important;
    min-height: 100% !important;
}

我想让div.col拉伸到100%的高度.我尝试了很少的东西,但没有一个能解决这个问题.我指望你的帮助.

提前致谢 !

Answer 1

1. 设置三个元素的容器(#footer-gradient)display: table
2. 并自己设置元素(.col)display: table-cell
3. 删除浮动.
4. 成功.

#footer-gradient {
    display: table;
}
#footer-gradient .col {
    display: table-cell;
    float: none;
}
