To add content blocks to your page, click on the icon in the upper right-hand corner.
To add a line block, used for styling and segmenting your page, drag this icon to where you want the media block to appear.

Feature: Line Settings
Once in place, you can edit your Line Block by hovering over the block area and clicking the Edit button.
Doing so will open the Line Settings panel. The colour, line weight, and line width (percentage compared to page width) can be modified.
Pro-tip: If you'd rather segment your page with blank spaces, use the Spacer content block instead.
