Getting Started

A CSS/JS theme library that applies iOS26 design system to Ionic applications.

DEMO is here: https://ionic-theme-ios26.rdlabo.dev/

Installation

In an existing Ionic project:

npm install @rdlabo/ionic-theme-ios26

Note: If you use @ionic/core@ < 8.8.1, use @rdlabo/ionic-theme-ios26@2.2.1.

And import the theme in your project's main CSS file (e.g., src/styles.scss).

@import '@rdlabo/ionic-theme-ios26/dist/css/default-variables.css';
@import '@rdlabo/ionic-theme-ios26/dist/css/ionic-theme-ios26.css';

/**
 * This file is to eliminate the impact of class name changes for iOS26.
 * For example, `ion-buttons ion-button[fill=default]` is not normally implemented, but may be required for iOS26.
 * This file is to eliminate such effects.
 * Note: This stylesheet is not included in `@rdlabo/ionic-theme-md3`.
 */
@import '@rdlabo/ionic-theme-ios26/dist/css/md-remove-ios-class-effect.css';

/**
 * If you will use the design of ion-item-group with ion-list on Android as well, import it.
 * More info: https://github.com/rdlabo-dev/ionic-theme-ios26/blob/v9.1.0/docs/using-ion-item-group.md
 * Note: This stylesheet is included in `@rdlabo/ionic-theme-md3`.
 * @import '@rdlabo/ionic-theme-ios26/dist/css/md-ion-list-inset.css';
 */

/*
 * Support Dark Mode
 * We support Ionic Dark Mode. More information is here: https://ionicframework.com/docs/theming/dark-mode
 * use Always:    @import '@rdlabo/ionic-theme-ios26/dist/css/ionic-theme-ios26-dark-always.css'
 * use System:    @import '@rdlabo/ionic-theme-ios26/dist/css/ionic-theme-ios26-dark-system.css'
 * use CSS Class: @import '@rdlabo/ionic-theme-ios26/dist/css/ionic-theme-ios26-dark-class.css'
 */

Configure animations

If you installed only the iOS 26 theme, configure its animations as follows.

import { isPlatform } from '@ionic/core'; // or @ionic/angular (Ionic 9), @ionic/angular/standalone (Ionic 8), @ionic/react, @ionic/vue
import { iosTransitionAnimation, popoverEnterAnimation, popoverLeaveAnimation } from '@rdlabo/ionic-theme-ios26';

// Angular
provideIonicAngular({
    ...
    navAnimation: isPlatform('ios') ? iosTransitionAnimation: undefined,
    popoverEnter: isPlatform('ios') ? popoverEnterAnimation: undefined,
    popoverLeave: isPlatform('ios') ? popoverLeaveAnimation: undefined,
});

// React
setupIonicReact({
    ...
    navAnimation: isPlatform('ios') ? iosTransitionAnimation: undefined,
    popoverEnter: isPlatform('ios') ? popoverEnterAnimation: undefined,
    popoverLeave: isPlatform('ios') ? popoverLeaveAnimation: undefined,
});

// Vue
createApp(App)
    .use(IonicVue, {
        ...
        navAnimation: isPlatform('ios') ? iosTransitionAnimation: undefined,
        popoverEnter: isPlatform('ios') ? popoverEnterAnimation: undefined,
        popoverLeave: isPlatform('ios') ? popoverLeaveAnimation: undefined,
})

Check the theme

Test on iOS. When previewing on desktop, set Ionic mode to ios in your existing framework initialization config (for example mode: 'ios').

Use this markup to preview the inset grouped list look. For the list structure the theme expects, see Using ion-item-group.

<ion-list mode="ios" inset="true">
  <ion-item-group>
    <ion-item><ion-label>Notifications</ion-label></ion-item>
    <ion-item><ion-label>Appearance</ion-label></ion-item>
  </ion-item-group>
</ion-list>

Optional: use the iOS 26 and MD3 themes together

Install the MD3 theme to style both Ionic modes from the same application.

The current releases of both themes require @ionic/core 8.8.1 or later.

npm install @rdlabo/ionic-theme-md3

When your global stylesheet uses Sass, initialize the themes in this order:

@use '@rdlabo/ionic-theme-ios26/src/styles/default-variables.scss' as ios26-vars;
@use '@rdlabo/ionic-theme-ios26/src/styles/ionic-theme-ios26.scss';
@use '@rdlabo/ionic-theme-ios26/src/styles/ionic-theme-ios26-dark-class.scss';
@use '@rdlabo/ionic-theme-ios26/src/styles/md-remove-ios-class-effect.scss';
@use '@rdlabo/ionic-theme-md3/dist/css/default-variables.css' as md3-vars;
@use '@rdlabo/ionic-theme-md3/dist/css/ionic-theme-md3.css';

The example uses Ionic's class-based dark mode. Your global stylesheet must also load Ionic's matching dark palette, such as @ionic/angular/css/palettes/dark.class.css for Angular. When using dark-system or dark-always, select the same variant for both Ionic's palette and the iOS 26 theme. See Ionic's Dark Mode documentation. The explicit ios26-vars and md3-vars namespaces prevent the two variable modules from using the same default namespace.

Configure both transition implementations when both themes are installed:

import { isPlatform } from '@ionic/core'; // or @ionic/angular (Ionic 9), @ionic/angular/standalone (Ionic 8), @ionic/react, @ionic/vue
import { iosTransitionAnimation, popoverEnterAnimation, popoverLeaveAnimation } from '@rdlabo/ionic-theme-ios26';
import { mdTransitionAnimation } from '@rdlabo/ionic-theme-md3';

// Angular
provideIonicAngular({
    ...
    navAnimation: isPlatform('ios') ? iosTransitionAnimation : mdTransitionAnimation,
    popoverEnter: isPlatform('ios') ? popoverEnterAnimation : undefined,
    popoverLeave: isPlatform('ios') ? popoverLeaveAnimation : undefined,
});

// React
setupIonicReact({
    ...
    navAnimation: isPlatform('ios') ? iosTransitionAnimation : mdTransitionAnimation,
    popoverEnter: isPlatform('ios') ? popoverEnterAnimation : undefined,
    popoverLeave: isPlatform('ios') ? popoverLeaveAnimation : undefined,
});

// Vue
createApp(App)
    .use(IonicVue, {
        ...
        navAnimation: isPlatform('ios') ? iosTransitionAnimation : mdTransitionAnimation,
        popoverEnter: isPlatform('ios') ? popoverEnterAnimation : undefined,
        popoverLeave: isPlatform('ios') ? popoverLeaveAnimation : undefined,
    });
