Dark Mode

Ionic makes it easy to change the themes of your app, including supporting dark color schemes. Dark mode is a display setting that changes all of an app's views to a dark theme. It has system-wide support on iOS and Android, making it highly desirable for developers to add to their apps.

Enabling Dark Theme​

There are three provided ways to enable the dark theme in an app: always, based on system settings, or by using a CSS class.

Always​

The default theme provided with Ionic Framework is a light theme, consisting of a light background and dark text. However, the default theme can be changed to the dark theme by importing the following stylesheet in the appropriate files:

@import '@ionic/angular/css/themes/dark.always.css';

This sets the application colors and stepped colors on the :root selector.

The following example will always display the dark theme, regardless of the system settings for dark mode.

Important

Avoid targeting the .ios or .md selectors to override the Ionic dark theme, as these classes are added to each component and will take priority over globally defined variables. Instead, we can target the mode-specific classes on the :root element.

System​

The system approach to enable dark mode involves checking the system settings for the user's preferred color scheme. This is the default when starting a new Ionic Framework app. Importing the following stylesheet in the appropriate file will automatically retrieve the user's preference from the system settings and apply the dark theme when dark mode is preferred:

@import '@ionic/angular/css/themes/dark.system.css';

This sets the application colors and stepped colors when the CSS media query for prefers-color-scheme is dark. The prefers-color-scheme media query is supported by all modern browsers. If support for older browser is required, we recommend using the CSS class approach.

The following example uses the system settings to decide when to show dark mode.

Avoid targeting the .ios or .md selectors to override the Ionic dark theme, as these classes are added to each component and will take priority over globally defined variables. Instead, we can target the mode-specific classes on the :root element.

CSS Class​

While the previous approaches are excellent for enabling the dark theme through file imports alone, there are scenarios where you may need more control over its application. In cases where you need to apply the dark theme conditionally, such as through a toggle, or if you want to extend the functionality based on system settings, we provide a dark theme class file. This file applies the dark theme when a specific class is added to an app. Importing the following stylesheet into the appropriate file will provide the necessary styles for using the dark theme with the class:

@import '@ionic/angular/css/themes/dark.class.css';

This sets the application colors and stepped colors on the .ion-theme-dark selector, which must be applied to the app by the developer.

The following example combines site settings, system settings, and the toggle to decide when to show dark mode. The site's theme takes precedence over system settings. If your system settings differ from the site's theme when the demo loads, it will use the site's theme.

Important

The .ion-theme-dark class must be added to the html element in order to work with the imported dark theme.

Adjusting System UI Components​

When developing a dark theme, you may notice that certain system UI components are not adjusting to dark mode properly. To fix this you will need to specify the color-scheme. See the browser compatibility for color-scheme for details on cross browser support.

While you may be mainly using Ionic components instead of only native components, color-scheme can also affect aspects of your application such as the scrollbar. In order to use color-scheme you will need to add the following HTML to the head of your application:

<meta name="color-scheme" content="light dark" />

This allows the page to indicate which color scheme it is comfortable being rendered with. Alternatively, you can add the following CSS to do this on a per-element basis:

color-scheme: light dark;
Default scrollbarScrollbar with color-scheme
Application without color-schemeApplication with color-scheme

For more information regarding color-scheme please see https://web.dev/color-scheme/.

note

color-scheme does not apply to the keyboard. For details on how dark mode works with the keyboard, see Keyboard Documentation.

note

For developers looking to customize the theme color under the status bar in Safari on iOS 15 or the toolbar in Safari on macOS, see theme-color Meta.

Ionic Dark Theme​

Ionic has a recommended dark theme that can be enabled in three different ways: always, based on system settings, or by using a CSS class. Each of these methods involves importing the dark theme file with the corresponding name.

The contents of each file are included below for reference. These variables are set by importing the relevant dark theme file and do not need to be copied into an app. For more information on the variables being changed, including additional variables for further customization, refer to the Themes section.

The always dark theme behaves in the following ways:

  1. Sets the Ionic colors for all modes to complement a dark theme in the :root selector. The :root selector is identical to the selector html, except that its specificity is higher.
  2. Setting variables for the dark theme on ios devices using the :root.ios selector.
  3. Setting variables for the dark theme on md devices using the :root.md selector.
caution

It is important to pay attention to the specificity if you want to override any of the Ionic dark theme variables. For example, because the --ion-item-background variable is set for each mode, it cannot be overridden in the :root selector. A higher specificity selector, such as :root.ios, is required.
