Customizing the Explore Page

Get rid of the MSN links
Use this CSS to kill the MSN ad links on the Explore pages:

.main-box { display: none !important; } /* Kill MSN boxes on the explore pages */

Get rid of the video in the editorials box
If you have placeholders on:

.editorials-content table .LJ_Placeholder_Container { display: none !important; } /* Kill Explore video editorial */

If not:

.editorials-content table object {display: none !important; } /* Kill Explore video editorial */

You can cover you bases by included both lines.

Other widgets
Widgets that also exist on the homepage can be altered on the Explore pages by the CSS in Customizing the Homepage.
