Sidebar position

Hi guys!!

I am trying to implement a sidebar in one of my pages. The problem is I can’t position content and sidebar in the same line (high).

The sidebar is wrapped in “archive-side” class with which I change the CSS and this class is inside the <div class=”entry-content”> function in the page code.

….
<div class=”entry-content”>

<div class=”archive-side”>
<?php get_sidebar() ?>
</div>

<?php the_content() ?>
…

I don’t know how to figure it out, no idea.

Thanks!
