And pls don’t tell me that https://www.cre8d-design.com/2008/03/how-to-organize-posts-into-two-side-by-side-columns-in-wordpress/ It doesn’t work.

Here is my content section’s codes:

<div id="container">

			<!-- ??erik Kutusu Ba?lar -->
			<?php if(have_posts()): ?><?php while(have_posts()): the_post(); ?>

                <div class="post" id="post-<?php The_ID(); ?>">

                    <h2><a href="<?php the_permalink(); ?>" title="<?php the_title(); ?>"><?php the_title(); ?></a></h2>

                        <div class="entry">
                             <?php the_content(); ?>
                        </div>
                </div>

			<?php endwhile; ?>
            	<!-- Navigasyon Ba?lar -->
                	<div class="navigation">
                    	<?php posts_nav_link(); ?>
                    </div>
                 <!-- Navigasyon Biter -->

				<?php else: ?>

                <div class="post">
                	<h2><?php _e('Hic Kayit Bulunamadi'); ?></h2>
                </div>

            <?php endif; ?>
        	<!-- ??erik Kutusu Biter -->

	</div>
