This adds extreme warmth to your store UI. When the user hovers over a product or card, we use a rapid box-shadow animation that cycles opacities and offsets to literally mimic a crackling fireplace!

Layered Shadow Flickers

.fire-card:hover {

Interact with the Live Demo. It perfectly replicates the gentle, uneven lighting generated by a hot winter fire!
