Particles `<mv-particles>`

Particules en canvas qui dérivent et scintillent, repoussées ou attirées par le curseur avec un retour élastique ; un mode constellation optionnel relie les voisines entre elles et au pointeur.

Catégorie	Arrière-plans
Type	Web Component (`<mv-particles>`)
Statut	bêta
Keywords	particles, sparkles, constellation, interactive, hero, canvas

When to use

A hero should respond to the cursor with drifting particles that scatter or gather
A network, AI or blockchain story fits a constellation of points linked to each other and the pointer
Ambient sparkle is wanted on a light or dark surface using the theme colors

Avoid when

Low-end mobile at high density with constellation links; a static CSS pattern is far cheaper → use Dot Pattern instead
