Overflow in code blocks is not scrollable

[hwittenborn]

I was just looking around because I was getting bored, and I stumbled on this project's website somehow.

Anyway, when visititing pages with code blocks (i.e. https://gorm.io/docs/connecting_to_the_database.html) and the line extends past the viewport width, the code gets cut off without any option to scroll.

It doesn't bother me too much to get this fixed quickly or anything, I just randomly noticed it and thought I'd report it.
