So when there isn't a template to do what you need, you have to know CSS and HTML, and must code yourself. The premise is "no-code". The uniqueness of this editor is it's ability to play nicely with anything you write yourself.
Nope. You don't have to code anything. That's the whole point. If you don't have a template, you start from a blank page and you build it using the GUI.
My original discussion point (top-level comment) was that feature alone doesn't sound like much of a differentiator from other WYSIWYG web builders out there.
That is, in fact, our main differentiator – and the main reason people choose Webflow. Check out this very diverse set of sites [1] that can be built with Webflow, this ability to visually develop any kind of custom layout/experience really does go a long way to distance us from any competitors.
These sites are quite varied, I do agree. One small thing I noticed. Some sites could have improved tab navigation, for example https://www.memberstack.io/. The site, without any interaction, is buttery smooth 60fps. When I start tabbing through the "What others are saying..." carousel, though, it destroys the animation frame rate (Chrome, Mac OS, 32 GB RAM).
Most WYSIWYG web builders are about assembling pre-existing blocks. Webflow gives you total freedom. Webflow is to Wix/Builders as Photoshop/Illustrator are to Canva.
