css - margin-top not working with clear: both

Question

<div style="float: left;">Left</div>
<div style="float: right;">Right</div>
<div style="clear: both; margin-top: 200px;">Main Data</div>

Answer 1

You could put the two floated divs into another one that's got "overflow: hidden" set:

<div style='overflow:hidden'>
  <div style="float: left;">Left</div>
  <div style="float: right;">Right</div>
</div>
<div style="clear: both; margin-top: 200px;">Main Data</div>
