> Respecting the Safe Areas

> The next step towards making our page usable again after adopting viewport-fit=cover is to selectively apply padding to elements that contain important content, in order to ensure that they are not obscured by the shape of the screen.

This is taking me back to the era of TV on CRT screens. Since there was always a bit of overscan, it was never a guarantee that the content at the very edge would actually end up visible to the end users, so the industry adopted a "safe area" 80-90% in each dimension (5-10% margin on each edge). Camera operators would avoid framing content such that important items are in that zone, and title generators would account for that margin to avoid having part of a text/subtitle cut off.

We've come full circle.
