The Webflow Style panel can be used to customize the Grid, Slider or Single 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
Youtube Feed will create Components of maximum 6 items on the Canvas—populated with dummy content—regardless of how many items you chose to show. Your choice will be exactly reflected on publish.
Only the first item counts in Webflow Designer. 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.
Only custom attribute count, not classes
Dynamic elements such as a view count, or a preview image, all have Custom Attributes attached to them, that's how the Component knows they have to be replaced with real content.
As long as you're not removing those Custom Attributes you can move the elements anywhere inside of the Instance element, to achieve the composition you want. You can create extra divs and wrapper, add content, change CSS position and order etc.
