Hello Arron and Lachlan,

Several tests, listed below, suggest (in their title and/or in their
meta assert) that the wider border wins over narrower border even when
'border-style: none' and 'border-style: hidden' are involved ... which
is not true. Even a 'border: red hidden 0px' should always prevail over
any other borders. Even a 'border: red none 100px' should always lose
over any non-zero narrow border.

Border conflict resolution where wider border wins over narrower border
is true only when border-style 'hidden' or 'none' is not involved
between 2 borders.

Hidden wins regardless of border width
--------------------------------------

http://test.csswg.org/suites/css2.1/nightly-unstable/html4/border-conflict-style-005.htm

says

"The 'hidden' border is the dominant border when it is collapsed with a
'dashed' border of the same size."
but that's not perfectly true. 'hidden' border style wins all the time,
regardless of its border width.


None loses regardless of border width
--------------------------------------

http://test.csswg.org/suites/css2.1/nightly-unstable/html4/border-conflict-style-027.htm
says

"The 'double' border is the dominant border when it is collapsed with a
'none' border of the same size."
but that's not perfectly true. 'none' border style "loses" even if it
has a bigger border width.


http://test.csswg.org/suites/css2.1/nightly-unstable/html4/border-conflict-style-068.htm
says

"The 'outset' border is the dominant border when it is collapsed with a
'none' border of the same size."
but 'none' border style "loses" even if it has a bigger border width.

regards, Gérard
