# React Card Component Styling

> Learn how to customize the React Card component with CSS classes, variables, and Sass for flexible styling and seamless integration into your design.

## CSS variables

React Card supports CSS variables for easy customization. These variables are set via Sass but allow direct overrides in your stylesheets or inline styles.

```scss
$card-tokens: defaults(
  (
    --cui-card-spacer-y: var(--cui-spacer-6),
    --cui-card-spacer-x: var(--cui-spacer-6),
    --cui-card-body-gap: calc(var(--cui-card-spacer-y) * .5),
    --cui-card-title-color: inherit,
    --cui-card-subtitle-color: inherit,
    --cui-card-border-width: var(--cui-border-width),
    --cui-card-border-color: var(--cui-border-color),
    --cui-card-border-radius: var(--cui-radius-7),
    --cui-card-box-shadow: none,
    --cui-card-inner-border-radius: calc(var(--cui-card-border-radius) - var(--cui-card-border-width)),
    --cui-card-cap-padding-y: var(--cui-spacer-3),
    --cui-card-cap-padding-x: var(--cui-card-spacer-x),
    --cui-card-cap-bg: var(--cui-bg-1),
    --cui-card-cap-color: inherit,
    --cui-card-height: auto,
    --cui-card-color: inherit,
    --cui-card-bg: var(--cui-bg-body),
    --cui-card-img-overlay-padding-y: var(--cui-card-spacer-y),
    --cui-card-img-overlay-padding-x: var(--cui-card-spacer-x),
    --cui-card-group-margin: #{$grid-gutter-x * .5},
  ),
  $card-tokens
);
```

### How to use CSS variables

```jsx
const customVars = {
  '--cui-card-cap-bg': '#555',
  '--cui-card-color': '#efefef',
}

return <CCard style={customVars}>{/* Card content */}</CCard>
```
