Scoping Variables to Components
Scope CSS variables to component elements to create isolated, reusable style systems.
Why Scope Custom Properties?
Global custom properties affect the entire page. Scoping custom properties to a component keeps styles isolated and prevents unintended inheritance across components.
Component-Level Scope
Define custom properties on the component's root selector. Children inherit them, but elements outside the component do not.
.card {
--card-bg: white;
--card-radius: 12px;
--card-padding: 24px;
background: var(--card-bg);
border-radius: var(--card-radius);
padding: var(--card-padding);
