I'm using the Twentyeleven theme and I'm having some trouble getting rid of margins. I'm using a child theme and it seems like the part of the code I want it to overwrite is not working. For instance, my sidebar is on the left hand side of the page and when I use firebug it says that #secondary margin-left is 7.6% or something. So I changed it to 0 in my .css and still nothing. I've tried a bunch of different things and haven't been able to get my #primary or #secondary to budge at all. Any help would be appreciated. My site is muscogeemp.com if you want to see for yourself.
Thanks in advance.
