<title>Test serialization of computed CSS variable values</title>

<!--

|

Adapted from https://dxr.mozilla.org/mozilla-central/source/layout/style/test/test_variable_serialization_computed.html
|

|

NOTE: CSS does not define the exact serialization of whitespace and comments
|
||||
(see https://drafts.csswg.org/css-syntax/#serialization)
|
||||
so an implementation could fail this test but still be conforming.

Adapted from https://dxr.mozilla.org/mozilla-central/source/layout/style/test/test_variable_serialization_specified.html

NOTE: CSS does not define the exact serialization of whitespace and comments

(see https://drafts.csswg.org/css-syntax/#serialization)

so an implementation could fail this test but still be conforming.
