I want to create a header with a background image. Now, the size of the image is 2748px wide and 349px high. And the image should always fit in. So I created this CSS code, but something is wrong.
height: calc(2748px / 100vw * 349px);

use `width:100%; aspect-ratio:2748/349;` or something like that – Temani Afif Aug 11 '22 at 00:18

@jsotola I know it because it says "invalid property value" – Luca Melop Aug 12 '22 at 10:06
