The Webflow Style panel can be used to customize the Grid or Slider layouts elements, such as Like and Comments counters, post description, slides, pagination, navigation... as there are no design limitations for Finsweet Components.
Only the first item needs to be populated and styled. Its content and styles will propagate to all other items on publish. If you want to achieve a better looking grid in the Designer, simply delete all items but the first one, and duplicate the first one as desired once styled. You can also use a Webflow Component to keep them all in sync in the Designer.
