A user is attempting to overlay an email signup form on top of a background video for their Shopify Dawn 7.0.1 password page. They provided initial CSS code for displaying different videos on desktop and mobile.
Progress Made:
BSS-Commerce provided CSS targeting the banner element with position: fixed, z-index: 100, and vertical centering using top: 50% and transform: translateY(-50%)
The desktop implementation is working correctly
Mobile video overlay was initially not functioning due to missing semicolons in the CSS
Current Issue:
A white bar appears at the bottom on mobile devices (image attached)
The user also asked about centering the email form on the page
Technical Details:
Solution involves media queries for responsive breakpoints at 749px/750px
May require adding !important properties if standard CSS isn’t taking effect
The discussion remains ongoing as the mobile white bar issue needs resolution
