Descripción general del botón de icono Angular
The Ignite UI for Angular Icon Button directive is intended to turn any icon into a fully functional button. The igxIconButton comes in three types - flat, outlined, and contained which is the default one.
Angular Icon Button Example
Getting Started with Ignite UI for Angular Icon Button
Para comenzar con la directiva Ignite UI for Angular Icon Button, primero debe instalar Ignite UI for Angular. En una aplicación Angular existente, escriba el siguiente comando:
ng add igniteui-angular
Para obtener una introducción completa al Ignite UI for Angular, lea el tema de introducción.
The next step is to import the IgxIconButtonDirective as a standalone dependency:
// home.component.ts
...
import { IgxIconButtonDirective } from 'igniteui-angular';
// import { IgxIconButtonDirective } from '@infragistics/igniteui-angular'; for licensed package
@Component({
selector: 'app-home',
template: `
<button igxIconButton="outlined">
<igx-icon>home</igx-icon>
</button>`,
styleUrls: ['home.component.scss'],
standalone: true,
imports: [IgxIconButtonDirective]
})
export class HomeComponent {}
Now that you have the Ignite UI for Angular Icon Button directive imported, you can start using the igxIconButton directive on elements.
Angular Icon Button Types
Flat Icon Button
Use the igxIconButton directive to add a simple flat icon button in your component template:
<button igxIconButton="flat">
<igx-icon>edit</igx-icon>
</button>
Contained Icon Button
All you have to do to create a contained icon button is to change the value of the igxIconButton property. Note that if you do not choose a type, by default it will also be set to contained.
<button igxIconButton>
<igx-icon>favorite</igx-icon>
</button>
Outlined Icon Button
Analógicamente podemos pasar al tipo delineado:
<button igxIconButton="outlined">
<igx-icon>more_vert</igx-icon>
</button>
Examples
Disabled Icon Button
If you want to disable an icon button, you can use the disabled property. In this sample we also demonstrate how to use icons from different families with the igxIconButton directive:
<button igxIconButton="flat" disabled>
<igx-icon family="fa" name="fa-home"></igx-icon>
</button>
SVG Icons
In addition to material icons, the igxIconButton directive also supports usage of SVG images as icons. To do so, first we should inject the IgxIconService dependency and then use the addSvgIcon method to import the SVG file in cache. For further information, you can read the SVG section in the icon topic.
constructor(private _iconService: IgxIconService) { }
public ngOnInit() {
// register custom SVG icon
this._iconService.addSvgIcon('rain', 'assets/images/card/icons/rain.svg', 'weather-icons');
}
<button igxIconButton>
<igx-icon family="weather-icons" name="rain"></igx-icon>
</button>
Tamaño
Users can choose one of the three predefined igxIconButton sizes by using the --ig-size custom CSS property. By default, the size of the component is set medium.
As you can see from the sample above, we can also use the igxIconButton directive to turn elements like span and div into Ignite UI for Angular styled icon buttons.

Siguiendo el enfoque más simple, usamos variables CSS para personalizar la apariencia del botón del icono:
[igxIconButton="contained"] {
--background: #011627;
--foreground: #fefefe;
--hover-foreground: #011627dc;
--hover-background: #ecaa53;
--focus-foreground: #011627dc;
--focus-background: #ecaa53;
--focus-border-color: #0116276c;
--active-foreground: #011627dc;
--active-background: #ecaa53;
}
Take a look at the icon-button-theme section for a complete list of available parameters for styling any type of icon button.
You can also choose to style only buttons of a specific type - flat, outlined or contained.
To do this, you can use the new type-specific theme functions: flat-icon-button-theme, outlined-icon-button-theme and contained-icon-button-theme
Here’s an example of using the contained-icon-button-theme function to define a custom theme in SCSS:
@use "igniteui-angular/theming" as *;
$custom-contained: contained-icon-button-theme(
$background: #ECAA53,
);
This will generate a fully themed contained icon button, including appropriate foreground and background colors for its various states like hover, focus, and active.
Styling with Tailwind
You can style the icon button using our custom Tailwind utility classes. Make sure to set up Tailwind first.
Junto con la importación de viento de cola en su hoja de estilo global, puede aplicar las utilidades de tema deseadas de la siguiente manera:
@import "tailwindcss";
...
@use 'igniteui-theming/tailwind/utilities/material.css';
The utility file includes both light and dark theme variants.
- Use
light-*classes for the light theme. - Use
dark-*classes for the dark theme. - Append the component name after the prefix, e.g.,
light-icon-button,dark-icon-button.
Once applied, these classes enable dynamic theme calculations. From there, you can override the generated CSS variables using arbitrary properties. After the colon, provide any valid CSS color format (HEX, CSS variable, RGB, etc.).
You can find the full list of properties in the icon-button-theme. The syntax is as follows:
<button igxIconButton class="!light-icon-button ![--icon-color:#FF4E00]">
<igx-icon>edit</igx-icon>
</button>
Note
The exclamation mark(!) is required to ensure the utility class takes precedence. Tailwind applies styles in layers, and without marking these styles as important, they will get overridden by the component’s default theme.
At the end your icon buttons should look like this:
