The maximum width of a default generated image-width.
The minimum width of a default generated image-width.
Representation of an image with a width of zero. This value is used in validation contexts, i.e. "is the width of the passed or requested image greater than or equal to the 'zero width image'."
The default density pixel ratios (dpr).
The srcset width tolerance dictates the maximum tolerated size difference between an image's downloaded size and its rendered size. For example, setting this value to 10.0 means that an image will not render more than 10% larger or smaller than its native size.
