# Atomic Styles

Elementor Core Advanced

An atomic style is a reusable class definition: it has an identifier, a user-facing label, and one or more variants. Each variant targets a responsive breakpoint and pseudo-state (meta) and holds a flat map of style props. Prop values are usually typed objects ($$type + value); see atomic prop values. The id is what ties the style to the data layer and to the generated CSS class; for some sources (for example global classes) the visible class name may follow the label instead.

# JSON Values

Argument	Type	Description
`id`	`string`	Stable id for the style (often aligned with the CSS class used in markup).
`label`	`string`	Name shown in the UI; may also drive the public class name depending on where the style is stored.
`type`	`string`	Style kind; `class` means a class-based rule (for example `.e-{id}`).
`variants`	`array`	One object per breakpoint/state combination; each entry has `meta` and `props`. Duplicate `meta` combinations must not appear on the same style.

# Example: breakpoints, states, and prop variety

Variants are keyed by meta.breakpoint and meta.state. Together they let one class describe a default look on desktop, a hover override on that same breakpoint, and a different default on mobile—each as its own object in variants. meta.state is usually null for the normal (non-pseudo) state; another entry with state: "hover" layers interaction styling. Props you omit in a variant are not set for that breakpoint/state pair, so narrow variants (for example hover only changing the background) stay small.
