I have been looking all over the forum for this solution. It seems like there are a few ways you have recommended to do it. I try to use the code you provide and put it in the Custom CSS under the style tab, and they either dont work or only resize the transparant part of the sidebar, the tabs stay the original size.
Im hoping you can provide me the code to insert that will make my sidebar roughly 40 – 50% thinner. If you can also have it move over towards the left of the page by about half of that gap that would be awesome, if not thats ok.
