Core login page and style changes to support mfa login workflow.
These are minor adjustments to core CSS and a core renderer
change to allow login workflow to better support MFA.
Changed introduced in da2f2c9c modified various zIndex attributes for
the page drawers. This has a side-effect of breaking the user tour of
the course page for the course index.
In the Moodle additions for the Bootstrap Dropdown we update the focus
after a 50ms delay. This is presumably because the targetted focus point
may not have shown yet and may be opened in a separate thread, though
sadly the original reasoning is not documented, and is not mentioned in
the original issues.
As a result of this delay, it was possible for the user to start to
interact and then have focus stolen from them. In reality this does not
happen often - 50ms is simply too short a time for a human to do so, but
it is plenty of time for Behat to do so and we have seen some random
fails as other parts of the UI become faster. When this happens,
keyboard focus tests are broken by this 50ms behaviour.
The fix here updates the shift focus function when closing the menu to
check whether the focus has changed from the previous location already
before setting the focus.
* Fix tag area text shadow colour. It is originally set to
`rgba(255, 255, 255, 0.5)` so it should be `rgba($white, 0.5)`
instead of `rgba($black, 0.5)`.
* Revert colour for `$content-item-unread-colour` to `#f4f4f4` instead
of `$gray-100`.
- Create a new SCSS file for dropdown related styles
- Move current dropdown styles from core.scss to new dropdown.scss
- Add helper classes for dropdown item colouring
Autocomplete fields can now include disabled options in the suggestion
list. When calling .enchance() on a select list with disabled options,
those options will be added to the autocomplete suggestions with the
aria-disabled arribute set, and will not be selectable.
Datafilters using the autocomplete element can also hook into this by
including disabled options in their list of values.
The footer button was missing some CSS to factor in the blocks drawer.
Also added noreferrer to the window.open call made when clicking the
communication button, to avoid the risks associated with opening in
_blank without removing access to the referrer and opener (noopener is
implicitly defined in modern browsers when noreferrer is set).
- The default box for the icons has been increased from 50px to 52px.
That way, on the course page, the box for the icons has changed from
30px to 32px.
- The icon size has been increased from 16px to 24px on the main course
page and from 24px to 40px on the activity page.
Action menus have a method set_kebab_trigger that converts the action
menu button into a proper kebab icon. However, this method does not
remove the standard bootstrap dropdown chevron and the visual
information is replicated (kebab icon + chevron). For now this method is
only used a couple of times but in every case (grade, course...) they
add unnecessary adhoc css rules to hide the chevron when it should be
the standard behaviour. This commit remove the chevron when the action
menu is displayed as a kebab menu.
* For consistency
* The font colour for .text-muted meets a contrast ratio of 4.69:1
which meets WCAG 2.1 Level AA success criterion for minimum contrast.
* The scroll value is not restored when we navigate into activities as only a
section of the page was scrolled.
* Remove the overflow for the page section so the full page is scrolled
* Restore side menu navigation synchronisation
This commit displays all the module forms together in the default
activity completion page:
- The checkboxes have been removed. Now the activity names are
displayed as accordions.
- Module names have been changed from plural to singular.
- The activity completion form is displayed below each module name,
when the chevron icon is expanded. The cancel button is not displayed.
- The CSS has been updated to meet the prototype styling.
