is it worth it to start learning css in 2026
Yes, if you want to work on Shopify stores in any real way.
Even with theme builders and apps doing more of the heavy lifting, CSS still pays off when you need to fix spacing, mobile layout, button styles, product cards, or little things that make a store feel polished instead of generic. You don’t need to become a front-end developer, but knowing enough CSS to read a theme and make small changes will save you a lot of time and money.
If I were starting now, I’d learn the basics, then Shopify specifics like flexbox, grid, responsive breakpoints, and how to target classes without breaking the rest of the theme.
Are you asking because you want to edit your own store, or because you’re thinking about it as a skill to get hired?
