Footer colons alignment

Hi,
first of all congratulations for the great job you did ! This theme is very useful :)
I have a small problem with the footer : I would like to have either two columns (with two stacked widgets inside) or three columns. My problem is that there is always a blank space on the right of the footer .
If you go on my website, you’lle that I currently have 3 widget in the footer, each one is in a column : Website language, Daphne Project, Contact us. And this empty space at the right of the “contact us” widget !!!
Is it possible to have 3 equal columns that match the whole width of the footer, or, even better, two columns with “website language + contact us” stacked in one of them, and Daphne project alone in the other ?
Many thanks for your help
