## What is the current behavior?
<!-- Please describe the current behavior that you are modifying. -->
As part of https://github.com/ionic-team/ionic-framework/pull/26976 I
fixed an issue where `pointer-events: none` was not applied until after
the menu open gesture finishes. This resolved a bug where scrolling was
latching after the menu gesture starts.
However, I did not account for the edge case where scrolling latches
_before_ `pointer-events: none` is applied in the DOM. Since scrolling
has already latched then `pointer-events: none` does not change the
scrolling behavior. This can happen if a user swipes up and to the right
from the left edge of the screen.
## What is the new behavior?
<!-- Please describe the behavior or changes that are being added by
this PR. -->
- `overflow-y: hidden` is now applied to the scrollable content which
will interrupt any scrolling when the menu is open.
## Does this introduce a breaking change?
- [ ] Yes
- [x] No

Testing:
This bug fixes a timing issue where scrolling latches on the main
content as the menu tries to open. As a result, I am unable to write
reliable automated tests for this. Reviewers should perform the
following test on iOS and Android physical devices:
1. Open `src/components/menu/test/basic`.
2. Add enough elements to the main page content such that it scrolls (I
added a list with items).
3. On each device, attempt to scroll the main content while also opening
the menu on the starting edge of the screen.
Scrolling on the main content should not happen if the menu opens.

## What is the current behavior?
The `system` and `always` dark theme files target the mode-specific
styles by using the following selectors:
```scss
:root {
@include dark-base-theme();
}
.ios body {
@include dark-ios-theme();
}
.md body {
@include dark-md-theme();
}
```
This is an issue because then users **cannot** override the dark theme
by targeting `:root.ios`, they must target the `body`.
## What is the new behavior?
Updates the mode selectors to target the `:root` with the mode-specific
class:
```scss
:root {
@include dark-base-theme();
}
:root.ios {
@include dark-ios-theme();
}
:root.md {
@include dark-md-theme();
}
```
This makes more sense, since we want it to still be global but
mode-specific, and allows users to override it on `:root` if desired.
## Does this introduce a breaking change?
- [ ] Yes
- [x] Maybe
- [ ] No
BREAKING CHANGES:
In previous versions, it was recommended to define the dark theme in the
following way:
```css
@media (prefers-color-scheme: dark) {
body {
/* global app variables */
}
.ios body {
/* global ios app variables */
}
.md body {
/* global md app variables */
}
}
```
In Ionic Framework version 8, the dark theme is being distributed via
css files that can be imported. Below is an example of importing a dark
theme file in Angular:
```css
/* @import '@ionic/angular/css/themes/dark.always.css'; */
/* @import "@ionic/angular/css/themes/dark.class.css"; */
@import "@ionic/angular/css/themes/dark.system.css";
```
By importing the `dark.system.css` file, the dark theme variables will
be defined like the following:
```css
@media (prefers-color-scheme: dark) {
:root {
/* global app variables */
}
:root.ios {
/* global ios app variables */
}
:root.md {
/* global md app variables */
}
}
```
Notice that the dark theme is now applied to the `:root` selector
instead of the `body` selector. The
[`:root`](https://developer.mozilla.org/en-US/docs/Web/CSS/:root)
selector represents the `<html>` element and is identical to the
selector `html`, except that its specificity is higher.
While migrating to include the new dark theme files is unlikely to cause
breaking changes, these new selectors can lead to unexpected overrides
if custom CSS variables are being set on the `body` element. We
recommend updating any instances where global application variables are
set to target the `:root` selector instead.
For more information on the new dark theme files, refer to the [Dark
Mode documentation](https://ionicframework.com/docs/theming/dark-mode).

## What is the current behavior?
<!-- Please describe the current behavior that you are modifying. -->
The light theme tokens are included in the starter apps but not in Ionic
Framework itself.
## What is the new behavior?
<!-- Please describe the behavior or changes that are being added by
this PR. -->
- The light mode tokens are bundled with Ionic Framework. This allows
developers to always have the light mode accessible to them including
the tokens.

The team would like to ensure that Ionic Framework components that use
an Ionic color (primary, secondary, etc) on top of a contrast color pass
minimum contrast ratios as defined in the WCAG.
## What is the new behavior?
<!-- Please describe the behavior or changes that are being added by

- Introduces a revised set of Ionic colors that pass AA color contrast
guidelines when with the appropriate contrast.

Older versions of WebKit used an old `constant()` syntax for safe area
variables: https://caniuse.com/?search=env
As of Safari 11.3, `env()` is supported instead. We haven't supported
Safari 11 in years, so I think this is safe to remove.

## What is the current behavior?
<!-- Please describe the current behavior that you are modifying. -->
Developers have requested that Ionic Framework support the dynamic type
feature on iOS for accessibility purposes. Ionic applications do not
respond to font scaling on iOS which can create inaccessible
applications particularly for users with low vision. Ionic apps on
Android devices currently support the Android equivalent due to
functionality in the Chromium webview.
Developers have also requested a way of adjusting the fonts in their
Ionic UI components consistently.
## What is the new behavior?
<!-- Please describe the behavior or changes that are being added by
this PR. -->
- Ionic components now use `rem` instead of `px` where appropriate. This
means devs can change the font size on `html` and the text in supported
Ionic components will scale up/down appropriately
- Add support for Dynamic Type on iOS (the iOS version of Dynamic Font
Scaling)

## What is the current behavior?
<!-- Please describe the current behavior that you are modifying. -->
The IonNav, IonRouterOutlet, and .ion-page elements have `overflow:
hidden` which prevent content from spilling out of it. This was likely
done to prevent these elements from having overflow scroll (since the
inner IonContent should be scrollable). However, this breaks the
translucency effect on IonTabBar because the content in IonContent can
not scroll under the IonTabBar.
```html
<ion-tabs>
<ion-router-outlet> <!-- this has overflow: hidden -->
...
<ion-content fullscreen="true">...</ion-content>
</ion-router-outlet>
<ion-tab-bar translucent="true">...</ion-tab-bar>
</ion-tabs>
```
In Ionic v3 components such as IonTabs and IonNav did have `overflow:
hidden`:
cf35d5eb7f/src/components/app/app.scss (L241-L246)
However, components like IonNav were not used inside of tabs at the
time, so the reported bug was not a problem then.
## What is the new behavior?
<!-- Please describe the behavior or changes that are being added by
this PR. -->
- Removed `overflow: hidden` from IonNav, IonRouterOutlet, and
.ion-page. This change seems safe to make because the `position:
absolute` and top/right/bottom/left values should ensure that these
elements take up the available screen space and avoid having overflow
scrolling.

this commit removes a globally injected style, `ionic.skip-warns.scss`,
from the project. this stylesheet was used to set a variable, `$Ionic`,
that would turn on/off deprecation warnings in (the also removed)
`ionic.deprecation.scss`. any file using either of the aforementioned
files have been updated.
this change is occurring while the stencil team is looking to improve
the size of generated components that use >1 mode. this deprecation was
a part of an initiative to remove sass source files from artifact
published to npm. while that was completed, this deprecation was not
removed (until now)

resolves#17583
BREAKING CHANGE:
The `[hidden]` attribute has been removed from Ionic's global stylesheet. The `[hidden]` attribute can continue to be used, but developers will get the [native `hidden` implementation](https://developer.mozilla.org/en-US/docs/Web/HTML/Global_attributes/hidden) instead. The main difference is that the native implementation is easier to override using `display` than Ionic's implementation.
Developers can add the following CSS to their global stylesheet if they need the old behavior:
```css
[hidden] {
display: none !important;
}
```
