Collapse DNN empty panes in Edit Mode

When a DNN page is in edit mode, the empty window panes are unnecessarily tall and force you to scroll to see your content. You can collapse the empty panes with a little CSS.

One way is to add the following to the portal.css page

.dnnModuleManager.dnnSortable {
    min-height: 22px!important;
}

Another way is to edit the css file that has the class that is making them too tall.

httpdocs\DesktopModules\Admin\Dnn.EditBar\Resources\ContentEditorManager\Styles

Line 9  min-height: 135px !important;

Change it to 22 px

min-height: 22px !important;

And save
