My theme is Mystique and I purchased the upgrade in order to customize. I would like to know if I can better distinguish my side columns/sidebars with a background color. If this option is available to me, how is it done? CSS? If CSS, where/how does one enter the code?
If you make the change, note that the sidebar area is a block that may stop short when the main content area has a lot of content in it. Try adding a test post with a lot of content to see what I mean.
