This is a Sass mixin to handle a 3-way dark mode. It relies on a data-theme
attribute on your <html>
element with a value of light
or dark
. If data-theme
is absent (i.e. it's neither light
nor dark
), the system's preferred mode is used.
body {
// matches data-theme="light" or data-theme="auto" with system instructing light mode
@include light {
background: white;
color: black;
}
// matches data-theme="dark" or data-theme="auto" with system instructing dark mode
@include dark {
background: black;
color: white;
}
}
See the example above on sassed
Caveat: This mixin targets modern browsers which support the :where()
pseudo selector. There is an older revision of this Gist with more caveats, but also with support for older browsers, which you can find here.
(edit: I was having a build error!) I do see that works, with the only sacrifice being that it is on body instead of root. Not bad at all! thank you
