Introduction
------------
This directory contains testsuites for CSS WG specifications, including ones
that do not strictly speaking define CSS features, e.g.,
[Geometry Interfaces](https://drafts.fxtf.org/geometry/).
The directories should be named like the specification's shortname, but without
any level suffix.
As the test harness relies on the largely undocumented old CSS build system,
this directory has a number of test requirements specific to it:
* support files for a given test must live in an adjacent `support` directory;
* tests must have a [`<link rel=help>`][spec-link] pointing to what they are
testing;
* for each spec so linked, test filenames must be unique; and
* support and reference files must have unique filenames within the entire
`css` directory.
