Safe Area Variables Using env() CSS


What does it do?

The env() CSS function can be used to insert the value of a user agent-defined environment variable into your CSS, in a similar fashion to the var() function and custom properties. The difference is that, as well as being user-agent defined rather than user-defined, environment variables are globally scoped to a document, whereas custom properties are scoped to the element(s) on which they are declared.

/* Using the four safe area inset values with no fallback values */

/* Using them with fallback values */
env(safe-area-inset-top, 20px);
env(safe-area-inset-right, 1em);
env(safe-area-inset-bottom, 0.5vh);
env(safe-area-inset-left, 1.4rem);
