Update: Styling footer modules

[valiha]

I managed to move some of my modules from the sidebar to the footer and place them one next to another, but I'm still struggling with centering them on the page. I would also like to have a uniform background color instead of the way it is now.

css I used to achieve the effect:

.module-section-three .module-wrapper {
background-color: #CFE0E6;
}

.module-section-three .module {
display: block;
float: left;
text-align: center;
background-color: #CFE0E6;
width: 140px;
height: 100px;
padding: 5px;
margin: 0px;
}

Can somebody please give me advice on this? Nothing I tried has worked. :(
