How can I fix notifications hidden by a floating header or menu?

If your theme implements a floating (or static) site header, navigation, or other elements and LifterLMS notifications are hidden or partially obscured by these items you can add this CSS to your site’s custom CSS area to ensure LifterLMS notifications display on top of these elements:

.llms-notification { z-index: 999999; }

If this doesn’t help, you may need to increase “999999” to a higher number until it displays on top of the obscuring element.

You can add this CSS via the Customizer.
