Skeleton Vue Component

Framework7 comes with Skeleton Elements library (aka UI Skeletons, Skeleton Screens, Ghost Elements) - UI for improved perceived performance.
Skeleton Elements library already integrated into Framework7 and you don't have to install it separately. For the full API documentation and more examples check out the official Skeleton Elements for Vue documentation.
