Toolbar buttons available on the block allows you to change the width of the block to Content Size, Wide Size or Fullwidth Size. Once the image is selected as a background, toolbar icon allows you to change the image displayed in a block. For Cluster with custom height defined are available options to align content vertically. You can align content to the top, center or bottom of Cluster block.
