Variants
Prefix any class with a variant to apply it only under that condition. Variants stack, as in @md:h:ff:m.
Breakpoints
Apply a class from a viewport width up. Each breakpoint covers its width & every width above it.
| @xs:ff:m | From 32rem up. |
| @sm:ff:m | From 40rem up. |
| @md:ff:m | From 48rem up. |
| @lg:ff:m | From 64rem up. |
| @xl:ff:m | From 80rem up. |
| @xxl:ff:m | From 96rem up. |
Containers
Apply a class from a container's width up, not the viewport's. Mark the parent with ct:is first.
| @c:xs:ff:m | Container from 32rem up. |
| @c:sm:ff:m | Container from 40rem up. |
| @c:md:ff:m | Container from 48rem up. |
| @c:lg:ff:m | Container from 64rem up. |
| @c:xl:ff:m | Container from 80rem up. |
| @c:xxl:ff:m | Container from 96rem up. |
Media
Apply a class when the device or the page matches a condition, or on the first frame an element renders.
| @pc:ff:m | On a touch screen. |
| @prm:ff:m | With reduced motion on. |
| @st:ff:m | On the first frame. |
States
Apply a class only while the element is in a state, such as hovered, focused or checked.
| h:ff:m | On :hover. |
| f:ff:m | On :focus. |
| fv:ff:m | On :focus-visible. |
| a:ff:m | On :active. |
| d:ff:m | On :disabled. |
| fc:ff:m | On :first-child. |
| c:ff:m | On :checked. |
| e:ff:m | On :empty. |
| fw:ff:m | On :focus-within. |
| i:ff:m | On :invalid. |
| in:ff:m | On :indeterminate. |
| lc:ff:m | On :last-child. |
| nc:ff:m | On :nth-child. |
| r:ff:m | On :required. |
| ro:ff:m | On :read-only. |
| v:ff:m | On :valid. |
Pseudo Elements
Style a part of the element rather than the element itself, such as its placeholder or the selected text.
| a::ff:m | On ::after. |
| b::ff:m | On ::before. |
| p::ff:m | On ::placeholder. |
| s::ff:m | On ::selection. |
Custom Fonts
Add a font stack in theme.fonts & use it by name. A name that matches a built-in family (d, m, s) replaces it.
