<div class = "box" style="width:100%;">
<div class = "left-side" style="width:50%;float:left;">
<div class = "inner-box" style="width:100%;">
</div>
</div>
<div class = "right-side" style="width:50%;float:right;">
<div class = "inner-box-right" style="width:100%;">
</div>
</div>
</div>
Is it possible to set the width of the "inner-box" or "inner-box-right" div to match the width of the "box" div using only CSS?
