Where can I write a custom CSS for my app?
"To write a custom CSS you have to go through the following procedure:
- when in your app go to the ""Settings"" section, on the right from the simulator. Then to the ""Advanced"" section.
- in the ""Advanced"" section there is a text area called ""Custom CSS"" where you can edit or paste your own custom CSS. Make sure you click on""Save"" before leaving this page. If you don't, the changes you make in the custom CSS won't be stored in the app"
