Block effect settings
Go to the "Effects" tab in the block editor. Here you will find settings for rounded corners and transition effects between blocks.
To configure rounded corners, use the slider in the "Rounded corners" section. For the rounding effect to be noticeable, you need to set a background color or background image, and we also recommend adjusting the outer margins.
In the "Transitions" section, you can configure various transition effects between blocks. You can choose the number of the top and/or bottom transition for your block.
Click the "Update" or "Add" button (if you have just selected a new block) to apply the changes.
