When you are using our latest default email boilerplate, you will find the block divider. You are not satisfied with the color and/or width of the block? Don't worry, you can change it easily.
Click at the divider and change either the width or margin (or both). Considering the mobile devices, it might be better to change the width to another % value than increasing the margin. When you want to have the divider as wide as the content block, remove the margins on the left and right side.
To change the color of the divider, click at the divider and change the background color with the color picker found below the box where you set the margin/border/padding.
