I was just curious if anybody knows if MoI's web browser engine supports something like CSS custom properties?

For example...

:root {
--main-color: #BBB;
}

html, body {
color: var(--main-color);
}

...I tried it, but it doesn't seem to work and I was curious if maybe there is another way to do it. This would be for the "moi.css" file ideally.
