});
```
MutationObserver
or a setInterval
to detect the class and then apply the unsupported property.Or:
onclick
attributes via an Embed component.<script>
inside (Webflow CVA allows this).To manipulate unsupported properties in Webflow, use custom JavaScript added via Project Settings or Embed components, and tie it to your elements using classes or custom attributes. This extends Webflow's native capabilities while keeping your logic maintainable.
