Root Cause

UI Toolkit USS/UXML selector not matching elements.

generic

Workarounds

  1. 88% success Check selector specificity and element class names match exactly
  2. 90% success Use UI Debugger: Window > UI Toolkit > Debugger to inspect elements

Dead Ends

Common approaches that don't work:

  1. Use inline styles for everything 78% fail

    Not maintainable, defeats USS purpose

  2. Add \!important to all rules 75% fail

    Defeats specificity system
