That feature can be easily implemented using breakpoints in the Wix Studio Editor, but with the Wix Editor, it will require a bit more creativity. To get straight to the point, you’ll likely need to implement the kind of coding discussed in the following topics. However, what this code achieves seems to be based on the assumption that the window size won’t change halfway through (the design adapts based on the window size when the site is opened). Therefore, to make the design dynamically adjust even when the window size is changed after opening the site, some additional adjustments will likely be necessary.
If you’re just starting to build your site and want to create a site that excels in responsiveness, I recommend rebuilding your site using the Wix Studio Editor. However, even if that’s not the case, it’s still likely possible to achieve that functionality. That said, you’ll probably need an event handler to detect when the window size changes.
To detect window size changes, you’ll need to use custom elements, fortunately, the answer to this has already been provided in the following topic!
