CSS for opacity in mobile app


I am trying to grey out a big tile link with "Temporarily unavailable" text. what I have currently done is overlayed a container and used the opacity CSS attribute to make the overlay translucent. this works for chrome but I can't get it to work on the mobile app. I have tried using RGBA colours as well ( background: rgba(128,128,128,204)). Is there a way to make a container translucent on the mobile app or is there another method I can use to get the same effect?




Maybe consider using a Popup instead with your message in mobile. 

Agree, it should be implemented by popup to use the good build-in stuff in outsystems

thanks i'll try that
