For one page websites scrolling is the solution to see more content, differently from regular websites where you click on a button that gets you on a page, then another one and if you are not focused and the site is not well structured, you can get lost in all the details that the pages have.
This is different with one page websites. Mostly being landing pages, information is not complex, instead they just have a few blocks of text, even fewer images, maybe a video and that’s it.
But what about designing a site like this? How would you do it? Most of the times, you can make them scroll vertically, but there are designers who decide to make things a little bit more interesting and make the websites scroll horizontally.
