# CSS Editor dumping “invalid” CSS?

 * Trying to add a bit of code to my CSS, and it won’t seem to save any code that
   it considers “invalid” — discovered this when trying to add this line to a class:
 * `-webkit-text-fill-color: transparent;`
 * After I save, the class comes back without that line in it. So I just jokingly
   added:
 * `WUT`
 * outside of any class, and sure enough, it didn’t save. Wrap it in comment tags,
   though:
 * `/* WUT */`
 * and it’s all good. So. The question — is this filtering an “undocumented feature”?
   Or is this something I can shut off?

 * Jetpack’s Custom CSS module does indeed remove invalid CSS on save, for security
   reasons.
 * Unfortunately, it looks like `text-fill-color` is considered as invalid as well;
   we’ll need to update Jetpack to support these new CSS properties.
