Topic summary
Goal: On mobile collection and featured collection, display compare-at price and sale price on the same line, with matching font sizes; optionally remove the “AUD” label to save space.
Key points:
- Initial problem: Prices stacked on separate lines and in different sizes on mobile.
- Constraints: Solution depends on theme; may require custom CSS/HTML changes.
Actions taken:
- Site URL was shared for review.
- A CSS-based approach was provided to place both prices on a single line and standardize font size on mobile. Guidance included where to add it (between tags or into the theme’s custom CSS) and to clear caches.
- Note: Removing the “AUD” label conflicted with existing setup but is feasible with additional effort.
Outcome:
- The original poster confirmed success after adding the provided CSS in the theme’s custom CSS section.
Open items:
- Another user reported the CSS did not work on their site (likely theme-specific differences). No follow-up solution yet.
Status: Resolved for the original store; unresolved for others who may need theme-specific adjustments or further customization.
