【备忘录】FF下table-cell and full width absolutely positioned children
<divclass="cell-1"> ------>display: table-cell;
<divclass="wrapper">
<divclass="content-1">this must be positioned absolutely</div>
<divclass="content-2">as these divs will be overlapping</div>
</div>
</div>
.wrapper {
position: relative;
}
solution: wrap content divs in another positioned div
