HTML Left and Right Align Elements

Question

To accomplish this I have done this:

<table style="width:100%;">
 <tr>
    <td style="width:50%;text-align: left;">left</td>
    <td style="width:50%;text-align: right;">right</td>
  </tr>
</table>

How could I accomplish this in the simplest fashion (least markup) without using tables? I just want to align 2 elements to the max left and right.

There are hundreds of 2 column layouts out there, but they more aligned for page layout, and seem overkill.

Answer 1

Some html:

<div class="left">left</div>
<div class="right">right</div>

Some CSS:

.left, .right {
  width: 50%; /* Floated elements technically need a width specified. */
}

.left {
  float: left;
}

.right {
  float: right;
}
