       <p>Another form of obscuring can occur where light boxes or other semi-opaque effects overlap the item with focus. While less than 100 percent opacity is not causing the component to be <q>entirely obscured</q>, such semi-opaque overlaps may cause a failure of <a href="../understanding/non-text-contrast.html">1.4.11 Non-text Contrast</a>. When a focus indicator can be covered by a semi-opaque component, the ability of the focus indicator to pass 1.4.11 should be evaluated (and pass) while the focus indicator is under the semi-opaque component. The intention in both situations is that the component receiving focus should never be obscured to the point a user cannot tell which item has focus.</p>

          <p>This SC contains a note regarding content that can be repositioned. If users can move content regions, then they can potentially position the movable content such that it obscures other content that may receive focus. In such a case, the author is only responsible for ensuring that the movable content <em>in its initial position</em> does not obscure the item receiving focus.</p>
