Turn sharp angles into smooth edges with the rounding corner tool. You can round corners on containers and structures with background colors.
Working with containers
Click a block on the canvas to make it the active layer.
Go to the Blocks heading on the side panel.
Click the arrow to move up to the container level.
On the side panel, add a background color and then use the plus (+) and minus (-) icons to round the corners. To adjust the font color, click the text and return to the Block level.
It's not possible to round the corners of an image. However, you can round the corners of the background color behind an Image block.
Working with structures
Click a structure on the canvas to make it the active layer.
Go to the side panel and change the background color of the structure.
Use the plus (+) and minus (-) icons to round the corners.
For greater design control, switch on the Separately toggle. Now you can round each individual corner of the structure.
