@B_David if your layout shows up distorted it could be an HTML error. If you’re missing open/close divs or any other containers in HTML, it will cause the rest of your site to show up improperly (in reference to your reply earlier about the sidebar, etc).
I can see tables in a gray box right under the Author Box with inline custom code added. Is that the part you’re trying to edit? Because I don’t see any code added to the CSS for that. If you make edits to the Author Box in the CSS it should show up.
