If you were wondering how to stretch out a background image so that it fills the whole page or section instead of tiling, read on!
Assign an image as the background image for your page, or section, by clicking on the "Change" button in the "Background Properties" panel.
Click on the "Stylesheets" button in the bottom left of the editor.
Paste in the following:
If you'd like to apply this to a page section instead, change #lp-pom-root to the ID of your page section.
That's it! Save and republish.
Please note, you will not see the scaling effect inside the editor. You should also bear in mind that there are different ways of scaling and positioning your background image. This example uses "cover" but you can read more about the background-size rule here.
Important: This trick relies on the user's browser having CSS3 support. All modern browsers support this, but it won't provide full compatibility with much older browsers.
