hi Andrew! ty for your reply!
i've been trying to make margin-left and right set to auto but its not working at all =(
tried putting them in both of #wp_page_numbers and #wp_page_numbers ul
When i check with FireBug, it seems to be automatically setting these values:
then i copyed these and put on my code, setting the values to 0, forcing them to be 0.
I dont even know why the code is putting those lines in first place >.<
Im checking your link now, ty Andrew!
