Website help

Question

I'm having trouble to understand the difference between js, jQuery and php.

Currently, I'm trying to create a website and so far I have several html files as well as css and js files.
Should I use php/jQuery and if yes, why? Is it linked to certain kinds of websites?

Can anyone help me out ?

Answer 1

Thank you!

So for clarification:
My website is a simple one, containing mostly just text and pictures. However, I have a contact form for emails.
In that case I don't need jquery, but I need php (for the contact form), right?
