The post no columns?

Hi,

in Custom CSS, put
.post-list .post, .post-list .page { width: 100%; }

in index.php
replaced

<div class="post-list group">
				<?php $i = 1; echo '<div class="post-row">'; while ( have_posts() ): the_post(); ?>
				<?php get_template_part('content'); ?>
				<?php if($i % 2 == 0) { echo '</div><div class="post-row">'; } $i++; endwhile; echo '</div>'; ?>
			</div><!--/.post-list-->

by

<div class="post-list group">
				<?php while ( have_posts() ): the_post(); ?>
				<?php get_template_part('content'); ?>
				<?php endwhile; ?>
			</div><!--/.post-list-->

So the posts are on a single column
