Mobile full 100WH Obscured by browser elements

[mashtaytey]

Hi Pablo
I have my layout grid set to Height: 100wh
On desktop, it works a treat.
However on mobile (safari, chrome), the full height is indeed the full height, but the bottom and top of my grid is obscured by the browser's own nav header footer.
Is there a way for the full height to be the exact viewable area within the browser's top and bottom nav borders?

also can you lazy load background images?

The 100vh is determined by the browser so you have no control over whether or not the browser's own nav header footer will be included.

In HTML, then is no lazy load option for backgrounds. it's only available for regular images.
