To stop using hard-coded values in CSS components, enforce a design system that defines all visual values as CSS custom properties. This requires component styles to reference standardized tokens for colors, typography, and spacing, eliminating scattered inline values.

Set up CSS custom properties for a web design system by defining color, typography, spacing, shadow, radius, and breakpoint tokens in your global stylesheet. This architecture creates a single source of truth that all UI components must reference for consistent styling.

Implement theme switching with CSS custom properties by mandating theme changes via data attributes on the root element. This approach dynamically overrides token values without altering individual component styles, ensuring consistent visual updates across the application.

The best way to enforce consistent spacing and typography across UI components is to apply a standardized CSS design system. This prohibits hard-coded values and requires all components to reference predefined spacing and typography tokens for visual consistency.

You cannot use !important in component styles when applying this CSS design system. The enforcement rules strictly forbid !important except for third-party overrides, ensuring that all visual values remain manageable through the standardized custom property tokens.

Your frontend UI looks visually inconsistent because of fragmented hard-coded values. Implementing a CSS design system solves this by providing a single source of truth for all visual values, ensuring every component references the same color, spacing, and shadow tokens.
