Can I use env()

Example, accounting for the safari toolbar in iOS versions 14 and 15, this css may be useful.

  #modal {
    /* overflow: scroll; */
    width: 100vw;
    position: fixed;
    height: calc(100vh - env(safe-area-inset-bottom));


Centering Content

Images Larger than Container

This will center the image inside of a element when the elements height and/or width is smaller than the image. This works well when you have image assets of various aspect ratios that you want to display as thumbs that are the same size.
