Utility Class Locking
Lock utility classes from accidental editing
Utility classes remains same regardless of your design. Generally, you should not edit utility classes. So we have locked down the option to edit class properties when you select our utility classes in Oxygen editor.
But incase you know what you are doing and want to edit our utility classes, please follow the below steps to do so.
When you select a utility class, you will see all the options disabled. If you go to the Advanced tab, you can see Lock selector styles checked.
Please uncheck the Lock selector Styles checkbox to edit the utility class.
