Adaptive template for pinaxproject.com

[marperia]

As of 2021, it's very unusual not to have a unadaptive design, and looks horrible:

It's really unusual that none of your CSS-files has a @media tag. So maybe we can just add some?
I think it would looks like something like this:
@media (min-width:320px) { .grid .grid-4 { width: 100%; } .grid .grid-2 { width: 50%; } }
And so on.

I can do it in my own, if you wish. Thanks for maintaining!
