The original
ProgressBar
-functionality is very old, and could thus do with some general clean-up.In particular, while it currently accepts various options those have never really been used in either the default viewer or in any examples. The sort of "styling" that these options provided are much better, not to mention simpler, done directly with CSS rules.
As part of these changes, the "progress" is now updated using CSS variables rather than by directly modifying the
style
of DOM elements. This should hopefully simplify future changes to this code, see e.g. PR #14898.Finally, this also fixes a couple of other small things in the "mobile viewer" example.
