You can add a background to your template. This can be either a solid color or an image.
Click the Backgrounds pane on the left side of the design area to open it. You'll see options for adding a background. You'll see the color palette where you can choose colors and you'll also background images that you can select.
Setting the background
Backgrounds are set on a per page basis. Select the page of your template that you'd like to set the background for first.
If you want a solid background color, click a color from the color palette in the Backgrounds pane.
If you want an image, click one of the images in the Backgrounds pane. You can scroll through the Backgrounds pane to see more options.
Note: If you don't see background images, that means the seller you purchased from has disabled this feature. You can still add a background image that you upload. Follow the instructions for uploading your own images here.
Editing the background
Editing the background is the same as setting the background. Just click a new color or image in the Backgrounds pane to change the background.
Deleting the background
To delete the background on your template, open the Backgrounds pane by clicking the Backgrounds menu item on the left side of the design area. Then click the red trash can icon in the Backgrounds pane. Be sure that the page is selected in the design area first.
