Spinner below is made with chosen config. These are spinner specific configs, global configs can also be applied to app spinners in application.
Spinner is shown on this entire section and blocks card.
Spinners will be shown "in-place", i.e. in button and in footer in this example. Inplace spinner does not block anything, any control needs to be blocked manually.
This shows a spinner with mask on entire window, blocking everything. A classic way of showing a loading spinner mask. Give it a try!
