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 #18279 fixes #20213 fixes #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; ```
@ionic/core
Ionic is an open source App Development Framework that makes it easy to build top quality Native and Progressive Web Apps with web technologies.
The Ionic Core package contains the Web Components that make up the reusable UI building blocks of Ionic Framework. These components are designed to be used in traditional frontend view libraries/frameworks (such as Stencil, React, Angular, or Vue), or on their own through traditional JavaScript in the browser.
Features
- Tiny, highly optimized components built with Stencil
- Styling for both iOS and Material Design
- No build or compiling required
- Simply add the static files to any project
- Lazy-loaded components without configuration
- Asynchronous rendering
- Theming through CSS Variables
How to use
Vanilla HTML
Easiest way to start using Ionic Core is by adding a script tag to the CDN:
<script type="module" src="https://cdn.jsdelivr.net/npm/@ionic/core@4.6.2/dist/ionic/ionic.esm.js"></script>
<script nomodule src="https://cdn.jsdelivr.net/npm/@ionic/core@4.6.2/dist/ionic/ionic.js"></script>
<link href="https://cdn.jsdelivr.net/npm/@ionic/core@4.6.2/css/ionic.bundle.css" rel="stylesheet">
Any Ionic component added to the webpage will automatically load. This includes writing the component tag directly in HTML, or using JavaScript such as document.createElement('ion-toggle').
Additionally, within this package is a dist/ionic.js file and accompanying dist/ionic/ directory. These are the same files which are used by the CDN, and they're available in this package so they can be apart of an app's local development.
Framework Bindings
The @ionic/core package can by used in simple HTML, or by vanilla JavaScript without any framework at all. Ionic also has packages that make it easier to integrate Ionic into a framework's traditional ecosystem and patterns. (However, at the lowest-level framework bindings are still just using Ionic Core and Web Components).
