What are Margins?
Margins act as a guide to help you maintain equal spacing from the edges of the page. They ensure that your text does not run too close to the page edge where it can risk getting cut off.
When you apply margins a line half an inch away from the edge of your page will be added to the design. The margins guide will only appear in the editor. That means that when you go to download, share or preview the design this line won’t appear.
How to Add Margins:
To add a margin:
Open the design and click on Alignment which can be found in the top right corner.
Click on Margins.
