This commit mainly improves three things:
- slide up/down animation of the modals on mobile, also allowing swipe down to close the modal
- body scroll locked modals, it means that only the body of the modal can scroll
- a new `<:headerPrimaryAction>` block for `d-modal` which when present will move the cancel button to the left of the modal title, and this primary action to the right of the title
This reverts commit d0d4a363d4. This causes issues for people that have specified explicit font sizes in their browser - reverting while we investigate. https://meta.discourse.org/t/300374
Previously we had an iOS-specific sizing rule which would increase inputs to `1.07em`, which would bring them over the 16px 'zoom on focus' threshold in some (but technically, not all) situations.
This commit does two things:
1. Updates the sizing rule from `1.07em` to `max(1em, 16px)`. Essentially: use the cascaded font size, unless it is smaller than 16px
2. Applies that sizing rule on all platforms. This will make Discourse design/theming more consistent across different devices
It also removes some associated CSS rules which no longer make sense.
This PR refactors the following:
* leaving all the CSS applied to the old `modal-body` classes in their respective files
* made new clean styling for `.d-modal` and refactored the template to use the new BEM classes
* `inner-`, `middle-`, `outer-` container classes are gone and replaced with simplified `wrapper` and `container` classes
* use standardised max-sizes with modifiers `-large` and `-max`
* lighter backdrop,
* min-width to prevent puny modals
* other styling changes regarding padding, close button,…
* pulled out all modal overrides into a general `modal-overrides` file + cleanup of outdated CSS
* pulled out login and create account modal styling into their own file, cause it's such a big override
* removed old general login.scss file for mobile & desktop
* only kept some remainders I don't want to touch in `app/assets/stylesheets/common/base/login.scss`
* UX: separate invite-signup styling
* UX: invite page centering
* remove old invites-show css
* UX: invite signup page – mobile
* remove class references in general file
* add styling for instructions
plugin/theme-breaking changes:
1. `controller:create-account` is gone (use `component:modal/create-account` in modifyClass, **if** absolutely necessary)
2. `create-account-body` css class is gone (target `.d-modal.create-account` or any of the inner classes: `.modal-outer-container`, `.modal-middle-container`, `.modal-inner-container`, or `.modal-body`)
1. Removes accidental bold from `text` and `multiselect` labels/placeholders
2. Adds the animated label/placeholder combo to `multiselect`
3. Makes the `multiselect` placeholder lighter to match other fields
4. Makes the `dropdown` values darker to match other fields
5. Removes the extra 5px spacing before `confirmation` fields
