Shopify supports Tailwind CSS

Shopify is a complete commerce platform for selling online and in person. You get a storefront and a back office in one place, with prebuilt themes (or AI-assisted design if you want to move faster), inventory and order management, marketing tools, and analytics. The same setup runs across channels, so a product can sell on your own site, in a retail shop through Shopify POS, on social, and through AI agents, with everything staying in sync. The same foundation works for a side hustle and a global brand.

Shopify Checkout with Shop Pay lifts conversion by up to 50%, and puts your store in front of the hundreds of millions of buyers who already have Shop Pay credentials saved. It's built into every Shopify store rather than something you bolt on.
