Let me explain to you how the “Next” button works
Here is a page where the Whole Screen is Wasted… on the Instructions for “Next” button.
This kind of design just blows my mind. How do people even come up with the ideas like that, at the time when everyone else is trying to reduce the amount of useless instructions and the number of clicks on screen? This is also borderline insulting for anyone who passed grade two in high school.
So, do we really need to explain to users how “Next” and “Previous” buttons work?
Designers sometimes forget that when users arrive on their site, they bring with them their knowledge of how websites work in general, as they’ve used web forms or applied for things online before…. on other sites.
Sometimes you may need to tweak your design and add more instructions, based on your understanding of your site’s users (e.g. how much time they spend online? what sites they use regularly? age considerations etc.), but in general, it’s a good idea to stick to web conventions and design based on best practices.
