/*
The following CSS variables define the main public API for styling Theia.
These variables should be used by all extensions wherever possible. In other
words, extensions should not define custom colors, sizes, etc. unless
absolutely necessary. This enables users to adapt the visual theme of Theia
by changing these variables.

Many variables appear in ordered sequences (0,1,2,...). For most of these
sequences, colors go from dark to bright for dark themes, and from bright to
dark for bright themes. A few sequences are used to create contrast against
the others, e.g. font and accent colors, and thus their brightness goes the
other way around.

Throughout Theia, we are mostly following principles from Google's Material
Design when selecting colors. We are not, however, following all of MD as it
is not optimized for dense, information rich UIs.
