How to avoid `.ui-btn-left` and `.ui-btn-right` being assigned to links in header?

These classes will position my first link to the left and my second to the right which is not what my designer had in mind when she designed my layout.

Trying to avoid manually overriding these classes or putting my links in a wrapper to duck away from the class assignment.

Thanks.
