position:absolute绝对定位引起的遮挡求解决

无名指甲 2016-06-15 04:32:20

三个层，div分别为
.HEAD
.MAIN
.FOOT

三个DIV层定位都是默认的。求怎么样让这个TAB下的内容不遮挡住FOOT层，小弟愚钝。求大神解决。能解决的直接发微信红包。小意思，但是心意绝对在！

其中，main里做了个选项卡TAB切换，tab切换的层其中有个层定位为，position:absolute 导致遮挡住了最下面的.FOOT层。
TAB切换的完整代码为
<style type="text/css">

.goodstabs {
width: 100%;
height:100%;
float: none;
list-style: none;
margin: 0 0 10px;
text-align: left;
}
.goodstabs li {
float: left;
display: block;
}
.goodstabs input[type="radio"] {
position: absolute;
top: -9999px;
left: -9999px;
}
.goodstabs label {
display: block;
padding: 14px 21px;
