Issue number: N/A - this does not completely resolve an issue but it
enables users to opt-in to having text wrap in a button by setting a
minimum height
---------
## What is the current behavior?
The current behavior when text is really long in a button is:
- Default buttons expand in width until part of the text (and button) is
off the screen and not in the visible viewport
- Block and full buttons horizontally align the text in the center and
overflow it on both sides (but the overflow is not visible so the text
is cut off at the beginning and end)
## What is the new behavior?
Allow the button height to increase when text wraps and add some padding
so that buttons with wrapped text still look nice. This does **NOT**
wrap the text in a button by default. That will be done in FW-4599.
- Removed `text-overflow: ellipsis` since this does not have any effect
- Changes `height` setting to `min-height` on all button types (small,
large, default) and buttons inside of an item, toolbar or list header
- Increases `padding-top` and `padding-bottom` on the buttons so that
overflowing buttons have padding around them
- Changes `.button-native` display property from `block` to `flex` in
order for anchor tags (`<ion-button href="#">` to align their text
vertically
- Sets `flex-shrink: 0` on slotted `start`/`end` elements to prevent
icons (and other elements) from shrinking to make room for the text
- Adds e2e test for button wrapping including the different types of
buttons that were changed by this PR
- Adds `ion-text-wrap` to the `ion-button` elements used in this test to
verify the height / padding changes are working as desired (to be
removed with FW-4599)
- Screenshot diffs are in the following PR:
https://github.com/ionic-team/ionic-framework/pull/27561
## Does this introduce a breaking change?
- [ ] Yes
- [x] No
<!-- If this introduces a breaking change, please describe the impact
and migration path for existing applications below. -->
## Other information
This does **NOT** wrap the text in a button by default. It only enables
buttons to look nicer and auto adjust their height/padding when the text
is wrapping.
After internal discussion we decided that automatically making the text
wrap inside of a button may have undesired effects on existing apps. For
example, if someone has a button inside of a list header with a long
label, the button will now wrap if it has a space or dash in the text
content.
Developers should set `ion-text-wrap` on the `ion-button` to opt-in to
text wrapping in a button, and this will become the default as part of
FW-4599 (the next major release).

- Update action sheet colors to match spec (md)
- Remove activated background on buttons (md - uses ripple)
- Update Segment Button to use proper indicator color when inside of a toolbar
- Add back input highlight on focus
fixes#20276
Before users had to know the exact opacity that the MD/iOS spec called for in order to change the hover or focused background color. This allows them to change the background without having to know the opacity.
- changes apply to Action Sheet (Buttons), Back Button, Button, FAB Button, Item, Menu Button, Segment Button, Tab Button
- greatly reduces the requirement by users to set the background hover, focused states for dark modes and custom themes, also eliminates the need to know what the hover opacity is for each based on the spec
- updates the MD dark theme per their spec
- adds a component guide for internal use changing Ionic components
references #18279fixes#20213fixes#19965
BREAKING CHANGE:
*Activated Class*
The `activated` class that is automatically added to buttons on press has been renamed to `ion-activated`. This will be more consistent with our `ion-focused` class we add and also will reduce conflicts with user's CSS.
*CSS Variables*
The `--background-hover`, `--background-focused` and `--background-activated` CSS variables on components that render native buttons will now have an opacity automatically set. If you are setting any of these like the following:
```
--background-hover: rgba(44, 44, 44, 0.08);
```
You will likely not see a hover state anymore. It should be updated to only set the desired color:
```
--background-hover: rgba(44, 44, 44);
```
If the opacity desired is something other than what the spec asks for, use:
```
--background-hover: rgba(44, 44, 44);
--background-hover-opacity: 1;
```
Reviews the `--width` and `--height` variables in each component to either remove or add them based on need.
- fixes a bug where the spinner color wasn't being set properly in loading
- adds css variables for customizing background, color, some borders in overlays
- fixes a bug where prefix, suffix are taking up too much width in picker

BREAKING CHANGES
## Core Components
Removes the `--width` and `--height` variables from the following components, in favor of CSS:
- Button
- FAB Button
- Checkbox
- Removes the `--width`/`--height` and adds a `--size` variable that is set on the width and height, allowing width and height to still be set and border-radius to still use it as a variable
- Radio
- Removes the `--width`/`--height` and `--inner-width`/`--inner-height` variables. Calculates inner values based on parent element size.
## Overlay Components
The following components have all be converted to shadow (or scoped) and have CSS variables for width/height:
- Action Sheet _(scoped)_
- Alert _(scoped)_
- Loading _(scoped)_
- Menu _(shadow)_
- Modal _(scoped)_
- Picker _(scoped)_
- Popover _(scoped)_
- Toast _(shadow)_
The above components will now have the following CSS variables for consistency among overlays:
| Name |
| ----------------- |
| `--height` |
| `--max-height` |
| `--max-width` |
| `--min-height` |
| `--min-width` |
| `--width` |
If the component does not set the value, it will default to `auto`.
## Removed CSS Variables
The following CSS properties have been removed:
| Component | Property | Reason |
| ---------------| --------------------| --------------------------------|
| **Button** | `--height` | Use CSS instead |
| **Button** | `--margin-bottom` | Use CSS instead |
| **Button** | `--margin-end` | Use CSS instead |
| **Button** | `--margin-start` | Use CSS instead |
| **Button** | `--margin-top` | Use CSS instead |
| **Button** | `--width` | Use CSS instead |
| **Checkbox** | `--height` | Use CSS or `--size` |
| **Checkbox** | `--width` | Use CSS or `--size` |
| **FAB Button** | `--width` | Use CSS instead |
| **FAB Button** | `--height` | Use CSS instead |
| **FAB Button** | `--margin-bottom` | Use CSS instead |
| **FAB Button** | `--margin-end` | Use CSS instead |
| **FAB Button** | `--margin-start` | Use CSS instead |
| **FAB Button** | `--margin-top | Use CSS instead |
| **Menu** | `--width-small` | Use a media query and `--width` |
| **Radio** | `--width` | Use CSS instead |
| **Radio** | `--height` | Use CSS instead |
| **Radio** | `--inner-height` | Calculated based on parent |
| **Radio** | `--inner-width` | Calculated based on parent |
This adjusts our Material Design button to match the updated spec for:
- transition timing
- outline border styles
- clear/outline hover background color
- updates components to use shadow DOM or scoped if they require css variables
- moves global styles to an external stylesheet that needs to be imported
- adds support for additional colors and removes the Sass loops to generate colors for each component
- several property renames, bug fixes, and test updates
