How to adjust announcement bar by height

Topic summary

Issue: After making the announcement bar and header transparent, a thin green line appeared at the top; the banner image didn’t cover the top edge.

Findings: The announcement bar had height: 5px, exposing the theme’s green background from its assigned color scheme (gradient/color-scheme-1).

Proposed fixes (most recent):

  • Announcement bar CSS: .shopify-section-group-header-group.announcement-bar-section { height: 40px; width: 100%; position: absolute; }.
  • Header CSS: .header-wrapper .header { margin-top: 35px; }.
  • Theme settings: Set the announcement bar’s color scheme background to transparent or assign a scheme with a transparent background.

Notes: Earlier suggestions included removing the 5px height, trying height: 100%, and ensuring position: absolute; the user briefly set height: 0px. Screenshots and CSS snippets were provided and are central to applying the fix.

Outcome: The first issue was resolved, but after following the final steps the user saw an all-white area. The helper advised reviewing and correcting all color schemes in theme settings.

Status: Ongoing. Next action is to adjust theme color schemes so the announcement bar remains transparent without forcing a white background.

Hello @Drews1k , I see that issue. It caused due to height is set to is 5px. Please make changes to them. See the screenshots below and change the CSS.

.shopify-section-group-header-group.announcement-bar-section {
    height: 5px; /* remove or comment this old css */
    height: 100%; /* add new css */
}

This is in green color because it comes from the color scheme that you assigned to it. See the screenshot below. The gradient and color-scheme-1 is taking bg color as a green.

to make the background transparent you have to make changes in that announcement bar scheme color or assign a new scheme to that.
