Props & events

Attributes & behavior classes

Spacing utilities have no JavaScript-facing "props" — every value is a plain, always-present CSS class you add directly to the element. .mx-auto centers a block-level element with a constrained width; the axis shorthands (.px-*/.py-*/.mx-*/.my-*) set both sides at once, while the single-side classes override just one.

No configuration attributes beyond the standard intent/style/size modifier classes.

Events

Purely CSS — flickui.js never touches these classes.
