With Editor X, Wix especially approaches designers and advanced users, similar to Webflow.
You have even more customization options than with Wix’s regular editor. Editor X allows you to build your site from scratch or adjust the available templates to your taste, through e.g. advanced “Grid Layouting”, “Text Scaling” and setting up “Custom Breakpoints”. Like that, you can create perfectly responsive websites and you don’t even have to use CSS.
The implemented developer mode (Wix Velo) contributes to the editor’s great flexibility as well.
