The width CSS descriptor is shorthand for setting both the min-width and the max-width of the viewport. By providing one viewport length value, that value will determine both the min-width and the max-width to the value provided.
Syntax
/* An example with one viewport value: */ @viewport { width: 320px; } /* An example with two viewport values: */ @viewport { width: 320px, 120px; }
