This is the most simple demo to make sure you're achieving the right structure in Webflow, and that the fullpage.js library works on your page.
Fullpage.js is complex and there's a lot of documention for you to read to implement it the right way. For instance, this demo kind of breaks Safari mobile bottom bar behavior, it's also not suitable to work with Webflow IX as is.
It also doesn't take into account situations where the sections are higher than 100vh, nor side scrolling slides and a lot of other aspect that fullpage.js handles very well when you set it up the right way.
Fullpage.js is free for your open source projects and your experiments, however you need to purchase a licence to use it on any other commercial and personal, non open-source project. Please check the pricing link below.More on fullpage.js websitefullpage.js Webflow integrationfullpage.js pricing
