Layer Priority and !important Interaction
Understand how layer order determines priority and how !important interacts with layers inversely.
Normal Declarations in Layers
For normal (non-!important) declarations, the cascade priority is:
- Unlayered styles (highest)
- Last declared layer
- Earlier layers (lowest)
!important in Layers — The Reversal
For !important declarations, the priority order reverses:
!importantin unlayered styles (lowest in !important tier)!importantin first declared layer (highest)!importantin later layers (lower)
