Skeleton Loader gives your users a sense that content is on its way. Rather than showing an empty screen or a generic spinner while data loads, you show grey placeholder shapes that mimic the layout of the real content, with a soft animated shine sweeping across them.
It is built entirely with CSS and a small amount of client-side logic no integrations, no external services, no configuration required to get started. Drop the block on a screen, bind one boolean, and you have a working loading state.
