A site like this will not only make the layout more difficult but also won't be optimized for SEO. The front end is the front end, and the back end is the back end. If you mix the two, you’re not really a programmer. Nowadays, it’s common to specialize in one skill. Even if you are full stack, you’ll likely know either JavaScript better than Python, or the other way around. I could say much more about this, but there’s not enough space here.
