Custom Footer


I tried to customize the footer of the BP-Colour Theme. In particular I would like to make it similar as the one of the eBP-Corporate Theme (represented in Footer2.png).
I edited the stylesheet.
In the Footer.png attached picture one can see what I get for my customized version of BP-Colour Theme. However it is different from the effect I would like to reach, which is depicted in Footer2.png.
Please could you help me?
Many thanks,
