Is horizontal scroll good?

Horizontal scrolling is a good option for design portfolios and photography sites where users need to go through multiple images quickly and easily. Navigating vertically in these situations is chaotic and puts a lot of strain on the user.

Is horizontal scroll good UX?

Horizontal scrolling involves more effort since users typically have to move their mouse pointer to a specifically designated area on the screen and drag (while holding the mouse button) or click. In addition to this, some horizontal scrolling implementations make the design judder and hence impair user experience.

Why is horizontal scrolling discouraged in Web pages?

Content hidden by a horizontal scroll is at a disadvantage because even salient visual cues don't offer strong information scent: users can hardly guess what information they will get once they click on an arrow or scroll horizontally.

Unless the interaction is a carousel, a timeline, or an intentionally horizontally structured feature, you should not be seeing a horizontal scrollbar.
