What can you change about a block's appearance?
Same block, different rhythm and emphasis. Blocks use your website palette and default spacing automatically, but you can override those defaults when a section needs something different: place it on a dark band, make the content wider or narrower, add more or less breathing room, hide it on phones, or show it only during a set period.
Select the block: in the Block view of the editing panel, colours, background photo, size, spacing and motion are in the Appearance group, and visibility, languages, schedule and anchor are in the Advanced group.
Under Motion you choose how the block enters the screen (for example Fade, Fade up or Slide) and, where the block supports it, what happens on hover and while scrolling. Only the effects the block can do are offered, and visitors who ask their device for less motion see the block in place.
