You can simultaneously animate more than one widget. Select all necessary widgets with Shift + click, and then proceed with Animation control as usual. All changes will be applied identically to each individual widget in the selection.
If you select a mix of animated and regular widgets you’ll be prompted to merge different animations so that each selected widget has identical attributes.
Note: full-width, full-height, fixed, and sticky widgets (see Fixed and positioned widgets) cannot be animated together or with regular widgets.
Hint: copy animation effects. Use Shift + Cmd + C/V to copy and paste animation effects from one widget and apply them to others.
