WordPress Block Theme Architecture: The 3-Layer CSS Approach

·


Modern WordPress block themes demand a structured approach to styling. We use a 3-layer architecture that keeps styles maintainable, performant, and future-proof.

Layer 1: theme.json Design Tokens

The foundation. Colors, typography, spacing, and layout constraints defined in theme.json. WordPress automatically generates CSS custom properties from these tokens.

Layer 2: CSS Variable Scoping

Component-level variables that compose theme.json tokens into reusable patterns — glass-morphism backgrounds, glow effects, transition curves.

Layer 3: Selector Overrides

Specific block style variations and component styles that consume the variables. This is where the visual magic happens — hover effects, animations, responsive adjustments.
