I recently came across a beautiful html5 template featuring horizontal mouse scrolling here. I'm not sure how they do it, so instead of trying to find that out, like any self-respecting coder I decided to come up with my own "better way". - Source: dev.to / almost 3 years ago
I would highly recommend https://bootstrap.build/ to configure a custom theme for Bootstrap. A different theme really changes things up, while keeping everything that is great about Bootstrap. Source: almost 2 years ago
