Topic summary

  • Issue: A store owner can’t find base.css in the Shopify theme code editor and asks where it is or to have it added.

  • Guidance provided:

    • Navigate in Shopify Admin: Online Store > Themes > Actions > Edit code. Then open the Assets folder and locate base.css. Screenshots illustrate the exact navigation and file location.
    • Another reply reiterates the two-step process with additional screenshots.
  • Clarification: Some themes don’t use base.css. The main stylesheet may be named theme.css or style.css; use whichever main CSS file appears in the Assets folder.

  • Status/outcome: No confirmation from the original poster that the file was found or edited. The thread remains open; next action is to check Assets for base.css or an equivalent main CSS file and edit that.

It doesn’t have to be base.css, some themes have theme.css, style.css, just pick one of them

Hi @PetsLaza

  1. In your Shopify Admin go to online store > themes > actions > edit code
  2. Find Asset > base.css.
