Here is the current layout structure I am working with:
div {
border: 1px solid
}
<div id="col_1" style="float:left;width:150px;">1</div>
<div id="col_2" style="float:left;width:100px;">2</div>
<div id="col_3" style="float:left;width:<REMAINING_WIDTH>;">3</div>
The first two columns, col_1 and col_2, have fixed widths. I am looking for the best approach to make the third column fill up the remaining space. Any suggestions on how to achieve this?
