Adjusting width not working on theme.

Hello,

My website is https://www.vincyezine.com. The site was built off the Soft Magazine theme. I’m however trying to convert it from a 3 section (content and 2 sidebar) to a 2 sections (content and one side bar)

This is what I’ve done.
I’ve changed the widths
#content {
overflow: hidden;
float: left;
width: 620px;
}

#sidebar-primary {
overflow: hidden;
float: right;
width: 280px;
margin-left: 15px;

and i have changed the sidebar.php to not include the sidebar section i don’t want. So now all that’s in the folder is this.

<?php global $theme; ?>

<div id="sidebar-primary">

    <?php
        if(!dynamic_sidebar('sidebar_primary')) {
            /**
            * The primary sidebar widget area. Manage the widgets from: wp-admin -> Appearance -> Widgets
            */
            $theme->hook('sidebar_primary');
        }
        $theme->hook("sidebar_primary_after");
    ?>

</div><!-- #sidebar-primary -->

I am using the editor section under appearance to edit the theme. I know it’s working because the secondary sidebar is done now, but i wont get the other columns to shift.

SOMEONE PLEASE HELP :S…
