How is web design for Shopify different from regular web design? There are some functions or screens that you should not do, because. it will not be possible to implement in the Shopify theme? Or are theme sellers writing this to get attention?

Answer 1

Shopify has its own markup language. More precisely, it is a mixture of html + css + js + "something else that resembles PHP". It's called Liquid. Lots of specific items. So a simple copy-paste from another system will not work. You can see it here https://shopify.dev/api/liquid
But it's better to create your own account, connect the default theme and see the built-in code editor. And then read the manuals.
