does wordpress theme development frontend developer work or blackened developer work?

Question

I think it's backend

Answer 1

We can also say that Java, python, ruby are back end languages, but they are also used for web designing (full front end).

PHP helps to maintain the theme modularity, that's why used in theme development.

Answer 2

Talk about the theme, it's for the show. It doesnt depend on the type of user accessing the site. So, it's front end developer's work.

Answer 3

while doing theme development have to use php a lot, but php is backend language?

Answer 4
