# Theming: styles, radius, density and sizes
## Read your style
`components.json` `style` is `<base>-<style>`: the part after the first `-` names the style (`base-nova` is nova on Base UI). The style is baked into `components/ui` and `components/reui` at install, so the installed files hold your real values: read your installed `button.tsx` (usually `components/ui/button.tsx`) for heights, radius and padding before you build anything that sits beside a control.
## The style ladder
<!-- gen:style-ladder:start -->
| Style | Button `sm` / default / `lg` | Button radius | Card radius, shadow | Card spacing | Button text |
| ----- | ---------------------------- | -------------- | ---------------------------------------------------- | ------------ | -------------------- |
| vega | `h-8` / `h-9` / `h-10` | `rounded-md` | `rounded-xl`, `shadow-xs` | 6, sm 4 | `text-sm` |
| nova | `h-7` / `h-8` / `h-9` | `rounded-lg` | `rounded-xl` | 4, sm 3 | `text-sm` |
| maia | `h-8` / `h-9` / `h-10` | `rounded-4xl` | `rounded-2xl` | 6, sm 4 | `text-sm` |
| lyra | `h-7` / `h-8` / `h-9` | `rounded-none` | `rounded-none` | 4, sm 3 | `text-xs` |
| mira | `h-6` / `h-7` / `h-8` | `rounded-md` | `rounded-lg` | 4, sm 3 | `text-xs/relaxed` |
| luma | `h-8` / `h-9` / `h-10` | `rounded-4xl` | `rounded-4xl`, `shadow-md` | 6, sm 4 | `text-sm` |
| sera | `h-9` / `h-10` / `h-11` | `rounded-none` | square, `shadow-sm` | 8, sm 5 | `text-xs`, uppercase |
| rhea | `h-7` / `h-8` / `h-9` | `rounded-2xl` | `rounded-[min(var(--radius-4xl),24px)]`, `shadow-sm` | 5, sm 4 | `text-sm` |
<!-- gen:style-ladder:end -->
Card spacing is the `--card-spacing` step (`--spacing(n)`) a Card pads with; `Card size="sm"` uses the sm step. The default Button text weight is `font-medium` (sera: `font-semibold`).
## What the style owns
- Never set what the style owns on its parts: radius (except `rounded-full`), height, horizontal padding, shadow, ring or font size. Pick `size` and `variant` instead.
- A panel is a `Card` or a `Frame`, never a div with `rounded-*`, `border` and `bg-card`; set density with `Card size="sm"` or Frame `spacing`.
- A bespoke element beside a control (a chip, a custom trigger) takes its height and radius from that control's row above.
- A focusable control you build copies the focus classes of your installed `input.tsx`.
- A variant before a class: `className` is for layout (placement, width, gap). `size-*` when width equals height, `cn()` for conditional classes (never a template literal), a scale step before an arbitrary value (`w-60`, not `w-[240px]`), no inline `style` for color or spacing, and no `z-index` on dialogs, sheets or popovers.
- Change the look through the theme CSS variables in `:root` and `.dark` (`--radius`, `--primary` and the rest) or with a style switch (a new `style` in `components.json`, which means reinstalling the components; ask the user first). Never edit installed files to restyle them.
## Components with no per-style values
`event-calendar`, `gantt`, `icon-stack`, `kanban`, `rating`, `scrollspy`, `sortable` and `timeline` install the same file in every style. Their look comes from your theme tokens and the parts you put inside them (a `Card` in a kanban column follows the style), so never copy another style's radius onto them.
