It helps that most mice have a vertical scroll wheel. Few have a horizontal one.
Exactly!
We're so accustomed to vertical scrolling on web pages. Decades at this point.
So when they want us to go horizontal it seems odd.
It's especially frustrating on pages with a lot of content. You have to scroll up and down to see all the stuff... but there's also stuff hiding in horizontal sliders that you might miss.
It's one thing if it's a single page with a horizontal slider. I think we can all figure that out.
But it's another thing if you have to go up and down... and sideways!
