Shimmer Patterns

Use simple classes to build shimmer UI Skeletons.

Setup

1. Add Shimmers to your page - see instructions under the files tab.
2. Create your shimmer html.
   • Wrap everything in the .shimmer class.
   • Use .rect for a rectangle.
   • Use .circle for a circle.
   • Use width utility classes to set widths.
   • Customise colors and border radius with css variables.

Example

<div class="shimmer">
  <div class="rect"></div>
  <div class="rect width-.75"></div>
  <div class="rect width-.5"></div>
  <div class="rect width-.25"></div>
</div>

Output

<div class="shimmer">
  <div class="circle lg"></div>
  <div class="rect width-.75"></div>
  <div class="rect width-.5"></div>
  <div class="rect width-.25"></div>
</div>

Output

Code
