Before you ship
5- 01Match content structure — Skeletons should mirror the size and layout of the content that will replace it, to reduce jumpiness on load
- 02Animation — Subtle motion to indicate loading without being too distracting. Can be a shimmer, pulse, or wave motion in the objects
- 03Style — Flat shapes with no depth, can be rounded or sharp
- 04Color scheme — Typically a neutral gray or very soft colour that does not call too much attention and contrasts just enough with its background
- 05Transition to real content — Should be a smooth, subtle movement like a fade out before the content loads
