ElectricFeet on "[Theme: Customizr] Text Area Under Footers"

OK, it's a bit confusing for us here, because it's not clear what you want. If you want one wide widget area, then all you have to do is what I suggested above:

Delete whatever you have in footer widget areas two and three and add:

#footer_one {
    width: 100%;
}

to your CSS.

That will give you one wide footer.

If you want them all to appear one after another, horizontally, then add:

.widget {
    float: left;
    margin-right: 20px;
}

to your CSS.
