How to create an e-commerce webpage using html only?

Answer 1

I don't think "html only" will enable you to achieve that.

I think there are template providers who offer the technology without you needing to code anything

Answer 2

It is not possible just using html. You need backend. An e-commerce website need to display thousand of products depending on the inventory and creating a separate page for each of them would be a tedious task. Instead you use the backend to show a page dynamically retrieved from database. There are many frameworks which helps in the backend. Alternatively, you can also use websites like Shopify or wordpress if you don't wanna code which gives you everything prebuilt.
