Help! What theme is this

Hello Everyone, cannot find the theme name for this template. I’ve tried searching in source code but am not computer literate at all. Any help would be very appreciated :

It’s not WordPress - looks like a custom build esp as it’s not responsive

What is an esp if you don’t mind me asking?

Especially - most stock themes or sites will be responsive (just an expectation of buyers now) and that link is not plus it looks a little outdated so almost certainly built to order

I believe Avada theme would do the same job or so

Thanks everyone!
