How to create e-commerce website

[tobistudio]

I really don't know how to make this question clear.

I realize e-commerce and blog websites are quit different from basic websites.

I am creating an e-commerce site from scratch, using HTML and CSS, javascript with a text editor (sublime text), which makes it tedious and time consuming.

I have different product pages (male cloths, female, baby, phones, jewelries, etc) of which are sub categorized under brands, types, styles, names, etc.

I also created a product detail / description, but I realize for each one all these thousands of products, I will have to create a description for all.

Is there any way to accomplish this without having to recreate a description page for each of these thousand products?

Thank you very much.
