Is horizontal or vertical scrolling better?
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.
How do you let users know they can scroll?
One way is to use a visual indicator. This could be a button or a line that shows users where they can scroll. This is helpful because it gives users a visual cue that they can scroll. You can use text to tell users they can scroll.
