The blog posts are divided in 2 sections, a sidebar on the left with only the date in it and the main area with your post content.
Is there a way to remove the sidebar and use all space for the posts content? I want the date to be displayed underneath the header of the posts.
In fact, exactly like the space the preview image uses.
I know html and css, I just don't know where to find the place to change it.
(this all apart from the official sidebar/widget area)
