When editing your newsletter design's layout, each layout comes with its own fully customizable group of settings. One of the customization options contained in the settings is the Border Radius.
To edit the Border Radius:
- In the editing area, hover your mouse over a layout to display the Actions menu.
- Click Settings to display the Layout settings in the editor's right pane.
- In Border Radius, enter the radius or use the up and down arrows to edit the radius from 0 (rectangle) to 2000 (circle). Adjusting the border radius basically changes the roundness of your layout.
