    Getting Started with Ignite UI for Angular Ripple Directive

    To get started with the Ignite UI for Angular Ripple directive, first you need to install Ignite UI for Angular. In an existing Angular application, type the following command:

    ng add igniteui-angular

    For a complete introduction to the Ignite UI for Angular, read the getting started topic.

    The next step is to import the IgxRippleModule in the app.module.ts file.

    // app.module.ts
    import { IgxRippleModule } from 'igniteui-angular';
    // import { IgxRippleModule } from '@infragistics/igniteui-angular'; for licensed package
        imports: [
    export class AppModule {}

    Alternatively, as of 16.0.0 you can import the IgxRippleDirective as standalone dependencies.

    // home.component.ts
    import { IgxRippleDirective, IgxButtonDirective } from 'igniteui-angular';
    // import { IgxRippleDirective, IgxButtonDirective } from '@infragistics/igniteui-angular'; for licensed package
        selector: 'app-home',
        template: '<button igxButton="contained" igxRipple>Click Me</button>',
        styleUrls: ['home.component.scss'],
        standalone: true,
        imports: [IgxRippleDirective, IgxButtonDirective]
    export class HomeComponent {}

    Now that you have the Ignite UI for Angular Ripple module or directive imported, you can start using the igxRipple directive.


    The igxRipple uses the Web Animation API and runs natively on browsers that support it. The web-animations.min.js polyfill is available for other browsers.

    Using the Angular Ripple Directive

    Adding Ripple Effect

    Use the igxRipple directive to add a ripple effect to the specified element:

    <button igxButton="contained" igxRipple>Click Me</button>


    Custom Color

    You can easily change the default ripple color using the igxRipple:

    <button igxButton="contained" igxRipple="white">White</button>

    Centered Ripple Effect

    By default, the ripple effect starts from the position of the click event. You can change this behavior using the igxRippleCentered property and setting the center of the element as origin.

    <button igxButton="contained" igxRipple="white" [igxRippleCentered]="true">Centered</button>

    Ripple Duration

    We can use the igxRippleDuration property to change the duration of the ripple animation, which, by default, is set to 600 milliseconds.

    <button igxButton="contained" igxRipple [igxRippleDuration]="2000">Click Me</button>

    Ripple Target

    Use the igxRippleTarget property to attach a ripple effect to a specific element inside a parent element.

    <div class="parent" igxRipple="white" igxRippleTarget=".child" [igxRippleCentered]="true">
        <button class="sample-button child" igxButton="contained">Read More</button>

    Notice that no matter whether you click on the parent or the child element, the ripple effect will only appear on the button.


    The child element, which you want to target with the igxRippleTarget property, has to be relatively positioned.


    First, in order to use the functions exposed by the theme engine, we need to import the index file, where all styling functions and mixins are located, into our style file:

    @use "igniteui-angular/theming" as *;
    // IMPORTANT: Prior to Ignite UI for Angular version 13 use:
    // @import '~igniteui-angular/lib/core/styles/themes/index';

    You can easily create a new theme, that extends the ripple-theme and accepts the parameters, required to customize the ripple as desired.

    $custom-ripple-theme: ripple-theme(
      $color: #217346

    Using CSS variables

    The next step is to pass the custom ripple theme:

    @include css-vars($custom-ripple-theme);

    Using Component Theme Overrides

    In order to style components for older browsers, like Internet Explorer 11, we have to use a different approach, since it doesn't support CSS variables.

    If the component is using the Emulated ViewEncapsulation, it is necessary to penetrate this encapsulation using ::ng-deep. To prevent the custom theme to leak into other components, be sure to include the :host selector before ::ng-deep:

    :host {
        ::ng-deep {
            // Pass the custom ripple theme to the `igx-ripple` mixin
            @include ripple($custom-ripple-theme);

    A color that is set using the igxRiple directive, would take precedence from the one, set within a custom theme.
