Variants

Prefix any class with a variant to apply it only under that condition. Variants stack, as in @md:h:zi:60.

Breakpoints

Apply a class from a viewport width up. Each breakpoint covers its width & every width above it.

@xs:zi:60	From 32rem up.
@sm:zi:60	From 40rem up.
@md:zi:60	From 48rem up.
@lg:zi:60	From 64rem up.
@xl:zi:60	From 80rem up.
@xxl:zi:60	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:zi:60	Container from 32rem up.
@c:sm:zi:60	Container from 40rem up.
@c:md:zi:60	Container from 48rem up.
@c:lg:zi:60	Container from 64rem up.
@c:xl:zi:60	Container from 80rem up.
@c:xxl:zi:60	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:zi:60	On a touch screen.
@prm:zi:60	With reduced motion on.
@st:zi:60	On the first frame.

States

Apply a class only while the element is in a state, such as hovered, focused or checked.

h:zi:60	On :hover.
f:zi:60	On :focus.
fv:zi:60	On :focus-visible.
a:zi:60	On :active.
d:zi:60	On :disabled.
fc:zi:60	On :first-child.
c:zi:60	On :checked.
e:zi:60	On :empty.
fw:zi:60	On :focus-within.
i:zi:60	On :invalid.
in:zi:60	On :indeterminate.
lc:zi:60	On :last-child.
nc:zi:60	On :nth-child.
r:zi:60	On :required.
ro:zi:60	On :read-only.
v:zi:60	On :valid.

Pseudo Elements

Style a part of the element rather than the element itself, such as its placeholder or the selected text.

a::zi:60	On ::after.
b::zi:60	On ::before.
p::zi:60	On ::placeholder.
s::zi:60	On ::selection.

Negative

Put a minus after the colon to negate a value.

zi:-10

A minus after the colon.
