* The aria-describedby attribute can be a list of element IDs that
describe the element. On form validation, the ID of the error message
container is added to this attribute which may already be containing
another ID. So we need to properly add/remove the error message ID
so that we don't delete any existing ID(s) in the aria-describedby
attribute during form validation.
version = 2020110900 release version
requires= 2020110300 current beta+ (week6roll1) version
Note that, because we are under parallel development period,
this is being done in the branch that is going to be released
(MOODLE_310_STABLE already existing) for Moodle 3.10.0 and
not in master, that is the one getting the bump under normal
(non-parallel) periods.
There are some unexpected differences between 310 and master,
better reconcile them now. Note this is not 100% critical but,
as far as nothing exclusively for 4.0 has landed to master yet
only branch/version differences should exist.
* Lighten info container.
* Fix colour contrast for the question container by
- Lightening the background a bit
- Darkening the text colour a bit
- Making sure the link colour has good colour contrast against the
question text.
* Fix colour contrast for the comments container by
- Lightening the text colour a bit
- Darkening the link colour a bit for better colour contrast against
the feedback text.
The current red, blue, and green colours achieve the minimum colour
contrast against a white background. However, when they're against
coloured background, text with these colours will easily fail the
4.5:1 contrast ratio requirement for Level AA.
The updated colours now have the following contrast ratio against a
white background:
* Blue - #0f6fc5 (5.12:1, from 4.58:1)
* Green - #357a32 (5.27:1, from 4.63:1)
* Red - #ca3120 (5.29:1, from 4.59:1)
