CSS env() Function
The env() function is used to insert the value of a user agent-defined environment variable into your CSS. It is almost the same as var() in CSS except these values are user-agent-defined rather than user-defined. These variables are globally scoped.
Syntax:
env( <custom-ident> , <declaration-value> )
Note: Please note that env() property values are case-sensitive.
Property values:
- SAFE-AREA-INSET-TOP: It defines the top of the rectangle from the edge of the viewport.
Syntax:
env(SAFE-AREA-INSET-TOP,Integer_value)
