/**
 * @file
 * WMD Solutions Base Theme - Background image/video block styles.
 *
 * Handles z-index stacking for any section with a full-bleed
 * background image or video with an overlay and content on top.
 *
 * Pattern:
 * .wmd-bg-section (position: relative)
 *   .wmd-bg-image or .wmd-bg-video  (z-index: 0, position: absolute)
 *   .wmd-bg-overlay                 (z-index: 1, position: absolute)
 *   .wmd-bg-content                 (z-index: 2, position: relative)
 *
 * Also supports MTT CorporatePlus class names for backwards compatibility.
