From time to time you need to change some things from the WordPress default. One of the easiest hacks to do is creating double posts columns.
all you need is a bit PHP and some Css tweaking, here is the example:
* change the width of the columns according to what you need.
in your index.php (in the theme folder) look for the posts loop and before that paste this:
<?php $col = 1; ?>
after the loop begins add this:
<?php if ($col == 1) echo “<div class=\”row\”>”; ?>
now inside the loop, replace the loop main DIV with this code:
<div class=”post col<?php echo $col;?>” id=”post-<?php the_ID(); ?>”>
and just before the end replace ENDWHILE with this:
<?php if ($col == 1) echo “</div>”; (($col==1) ? $col=2 : $col=1); endwhile; ?>
