3. We'd like to get some feedback from web developers, and
agreement from other browser vendors, about exactly which glyphs
are most appropriate to use for these disclosure states. We
considered two alternatives, but we think these three glyphs are
the most appropriate. U+25B8 (▸) BLACK RIGHT-POINTING SMALL TRIANGLE
U+25C2 (◂) BLACK LEFT-POINTING SMALL TRIANGLE
U+25BE (▾) BLACK DOWN-POINTING SMALL TRIANGLE
Yup, looks good.
FWIW I don't think we need cross-browser agreement here.
I strongly agree, because agreement on icons would work against the idea of
competition and variation between platforms and browsers as well as the idea
of platform-wide conventions that users may be accustomed to.
On the technical side, the characters proposed are not visually obvious -
being regular triangles, they are subject to variation on how they are seen
as pointing somewhere. U+25C2, especially in isolation, might be seen as
pointing to northeast...
Besides, when I first looked at the quoted text, I was using an Android, and
all the triangles appeared as replaced by small rectangles. So their font
coverage isn't particularly good.
In particular I think browsers should be free to implement <details>
using a platform-native disclose widget if they like. These are not
all alike e.g. OSX uses something like ▸, Windows something like [+]
(I think?) and Gnome (at least with the skin I have) something like ▷.
A key issue in making <details> work for users, and therefore motivating
authors into using it, is how to make it as obvious as possible to
understand that there is some detailed information available, though
currently hidden, and that there is an obvious way to get to it. This is
quite a challenge - but to visual designers and usability experts and
implementors, not to people who write general specifications.
Hopefully, _several_ essentially different experimental (or other)
implementations will emerge, will be discussed and tested, and some
successful ideas will prevail.
