Behaviors

The skeleton loader uses a subtle, left to right, gradient animation to indicate background activity.
Best Practices
1. Why us a Skeleton Loader
Skeleton loaders are perceived as loading quicker than blank screens and a spinners.¹ Users are also more likely to wait for content to load if they have a visual representation of what content is coming.³
2. Skeleton Loader vs Loader
Use a skeleton loader when loading larger pieces of content such as tables or lists. Use the loader for smaller, more compact pieces of content such as cards.¹

3. Match the structure
Ensure the loader accurately reflects the final layout of the elements it's replacing, including hierarchy and dimensions.²

4. Quick Loading Times
Don’t use a skeleton loader if the loading time is less than 1 second. Using one can create a strange user experience where a skeleton loader quickly flashes on the screen.¹
