1px Apple Safari bug

Try rendering this html in safari and you'll see what I mean. It does
not show up in Firefox.

<html>
<body style="margin:0;padding:0;">
  <div style="width: 70%;background:black;float:left">
    asdf
  </div>
  <div style="width: 30%;background:blue;float:right;">
    asdf
  </div>
</body>
</html>

try

<html>
<body style="margin:0;padding:0;" >
  <div style="display:table;width:100%;">
    <div style="display:table-row">
       <div style="display:table-cell;width: 70%;background:black;">
               asdf
       </div>
       <div style="display:table-cell;width: 30%;background:blue;">
               asdf
       </div>
    </div>
  </div>
</body>
</html>

Perfect, thanks!
