Topic summary
Topic: Aligning the “50% OFF” sale label with the product price and reducing extra spacing under pricing.
-
Issue: The sale badge appeared slightly above the price instead of centered. The user also wanted to shrink the white space between the price and the stock notification.
-
Context: A screenshot was shared for reference, and the store product URL was provided to diagnose the layout.
-
Solution provided: Edit the theme stylesheet (Online Store > Themes > … > Edit Code > base.css). Add a CSS rule targeting
product-info .price.price--large.price--on-saleto use Flexbox and adjust spacing. -
Code specifics:
display: flex; justify-content: center; align-items: center; margin-bottom: -12px;. This centers the badge with the price and decreases the bottom margin. -
Outcome: The change resolved the alignment and spacing issues. The user confirmed success, and the thread is effectively resolved.
