Cursor Snap `<mv-cursor-snap>`

Efecto de puntero premium que conserva el cursor del sistema: una placa suave se adapta al enlace o botón bajo el puntero (su caja y su radio de esquina), entra con suavidad, se inclina un poco hacia el puntero y se desliza entre objetivos. A diferencia de los cursores personalizados, no oculta nada y hace visible el área de clic, y el foco del teclado recibe la misma placa.

When to use

A marketing site or portfolio wants a polished hover effect on its nav and buttons without replacing the cursor
A toolbar or icon row should show a highlight that glides from one button to the next
Hover and keyboard focus should share one clear affordance on links, buttons and tabs
Small or tightly packed targets should reveal their clickable area as the pointer approaches

Avoid when

The design calls for a custom dot-and-ring cursor with labels such as 'View' → use Cursor Follower instead
A single hero button should be pulled toward the pointer → use Magnetic instead
A tooltip, not a highlight, should travel between toolbar buttons → use Tooltip Group instead

API

Attributes

Name	Tipo	Default	Description
`global`	boolean		Whole page instead of the element's own content: place one empty `<mv-cursor-snap global>` anywhere (the plate is attached to `<body>`, fixed to the viewport).
`targets`	CSS selector	`a[href], button:not(:disabled), [role='button']:not([aria-disabled='true']), [role='tab'], summary, [data-snap]`	Elements that receive the plate.
`disabled`	boolean		Turns the effect off and removes the plate.
`data-snap (on your elements)`	(empty) \| off		Empty: opt any element in (a card, a custom control). off: never highlight this element.

Properties

Name	Tipo	Description
`current`	Element \| null	Element the plate is on right now (read only).

Content structure

Name	Description
`(content)`	The area where the effect applies (unless global).

CSS classes

Name	Description
`mv-cursor-snap-plate`	The single highlight element, created by the component (aria-hidden, pointer-events: none).

CSS variables

Name	Default	Description
`--mv-cursor-snap-color`	`accent at 11%`	Plate fill.
`--mv-cursor-snap-ring`	`accent at 26%`	Hairline inside the plate edge (transparent to remove).
`--mv-cursor-snap-pad`	`0.25rem`	How far the plate extends beyond the target's box (0 = flush).
`--mv-cursor-snap-radius`	`var(--mv-radius-md)`	Corner radius used when the target itself has square corners (otherwise its own radius plus the pad).
`--mv-cursor-snap-z`	`var(--mv-z-cursor)`	Stacking order of the plate.

Accessibility

The system cursor is never hidden, replaced or resized, so OS cursor size and contrast settings keep working; the plate only makes the target's real hit area visible (helps motor accuracy). The plate is decorative (aria-hidden, pointer-events: none) and adds nothing to the accessibility tree. Keyboard: a target reached with :focus-visible gets the same plate, so keyboard and pointer users share one affordance (it adds to, never replaces, the element's own focus ring). The pointer part runs only under (hover: hover) and (pointer: fine) and ignores touch; keyboard focus works everywhere. Typing hides the hover plate until the pointer moves again. Reduced motion (OS or data-motion="reduce"): no easing, parallax or glide, the plate simply appears on the hovered or focused target. Forced colors: a Highlight outline instead of the tinted fill, without motion. Disabled buttons and aria-disabled controls are skipped. Transforms only (the plate is resized once per target, then scaled), one element, a frame loop that stops as soon as the plate rests; everything is removed when the element is removed.
