Best practices
Do:
Use skeleton cells which are in the same positions and a similar shape to the content that will replace them.
Show loaded data as soon as possible, replacing the skeleton cells.
Use a shimmer animation to show that content is being loaded.
Display a corresponding error message if lazy loading fails.
