space and footer bar

I am wondering how to get about 20px space over my footer bar so my other content is not resting on it.
Thanks

In your stylesheet, find this rule

Code:

---

#navMainWrapper, #navSuppWrapper, #navCatTabsWrapper {

        margin: 0em;

        background-color: #000000;

        background-image: url(../images/tile_back.gif);

        padding: 0.5em 0.2em;

        font-weight: bold;

        color: #0066CC;

        height: 1%;

        }

---

and add this rule after it

Code:

---

#navSuppWrapper {margin-top: 20px;}

---

thanks very much =)
Love it when the answer is simple and I appreciate your time greatly.
