In Showit you have numerous options for customizing your site, one really great feature is canvas backgrounds.
Canvas Background Types
Image
Solid Color
Typically, most canvases in your design will be set by default to a solid color option. Some canvases may utilize a canvas background image to create a visual impact with something like a large hero image. If you see an image on a canvas that takes up the entire canvas and which you cannot click to select, that is likely a canvas background image.
You can access the image by clicking the canvas it's on, and then going to the Canvas Background tab in the Properties Panel on the right.
Split/Merge
By default your canvas backgrounds will likely be synced, to style them differently simply hover over the Media Type or Fill options and then click on the three dots to the right of that option. Then click Split Mobile and Desktop in the drop down that appears.
You can then click between the mobile and desktop icons, so that you can customize your mobile and desktop canvas backgrounds independently.
Canvas Background Videos
Canvas background videos are a really great way to bring a fun and engaging element to your site. Perhaps it shows you at work, doing what you do best, or showcasing your beautiful product. There are some limitations to file types and sizes with canvas background videos which you can learn more about in this article.
There you have it! You can quickly and easily customize your design using the canvas background feature.
