Want to make your WooCommerce store feel faster without changing your hosting or plugins? Add shimmer effects. They give users the sense that content is loading—even when it’s just delayed by the DOM or API.

What’s a Shimmer Effect?

Shimmer is a CSS animation that creates a moving light gradient. It’s used to simulate loading content before actual data appears—great for product grids, cards, or blog previews.

How to Code It

Add this CSS:

.shimmer{ background: linear-gradient(90deg, #eee 25%, #f5f5f5 50%, #eee 75%);
background-size: 200% 100%; animation: shimmer 1.5s infinite}@keyframes shimmer{ 0%{ background-position: -200% 0;}
100%{ background-position: 200% 0;}}

Apply it to placeholders like:

<div class="product-placeholder shimmer" style="height: 180px; border-radius: 8px"></div>

Pro Tip:Use different shades for dark mode, and layer multiple shimmer blocks with varied animation delays to make it feel organic.

Don’t just load fast—look fast.
