Store Design

Topic summary

A store owner wants to increase the font size specifically for product descriptions on their Shopify store.

Two CSS solutions were provided:

  1. base.css modification: Add CSS targeting .m-tab-content--description pre p { font-size: 16px; } to the end of the base.css file (Shopify Admin → Online Store → Themes → Edit code).

  2. theme.liquid modification: Insert custom CSS in a <style> tag above the </body> tag in theme.liquid, targeting .m-tab-content--description pre p with the desired font size.

Both approaches use CSS to target the product description container. The second solution includes a visual reference image showing the expected result. The discussion appears resolved with actionable code snippets provided.
