Linter warnings for newer CSS properties/values

Was wondering what CSS linter glitch uses as the newer CSS properties don’t seem to be supported. The ones I’ve encountered so far are:

grid-template-columns: 1fr 1fr; /* Unexpected token '1fr' at line X */
grid-gap: 1em;  /* Unknown property 'grid-gap' */
gap: 1em; /* Unknown property 'gap' */

Thanks @huijing. We’d definitely like to enhance our linter support in the future - as things stand right now we’re pretty reliant on what comes with CodeMirror out of the box.

We’d certainly welcome a new topic (or a vote for an existing one) at
