The Edge to Edge feature, allows you to have the lightbox background hit the full width of your website. A lot of customers refer to this as a Full Bleed. As the background is stretched horizontally, the rest of the lightbox will remain centered.
Clients most often use the Edge to Edge feature for mobile lightboxes to create banners or sidebar lightboxes that fill the entire top or bottom portion of the screen.
How do I preview Edge to Edge?
You can preview by using the Preview on a Blank Site feature under Save & Preview.
Are background images stretched horizontally?
Only If you select Stretch in the Background section, under Repeat.
Do you have any best practices?
Only use Edge to Edge for Banner, Sidebar, and Inline lightbox types. Limit the maximum height of Edge to Edge lightboxes to 125 for mobile and 150 for desktop and/or tablet.
This feature works extremely well on inline and banner widgets. However, you can use it with any widget type.
