One more CSS issue – margins not resizing

Hi all, I have changed every single margin and padding setting that I can find, and the margin size in the post entry is not changing. I want to drastically decrease the left margin in the post entry, and slightly decrease the size in the right margin.

I’ve also used Firebug and do not see what is causing this, but again, it’s not working properly for some reason on this computer.

You guys helped tremendously on my last issue, and this should be it. I’ve figured just about everything else out. I suppose from now on I’ll create my own themes. I thought it would be quicker to modify an existing one, but I think I’ve changed my opinion on that!
