Predefined Icons Library in Syncfusion Angular Component

19 Sep 20248 minutes to read

Syncfusion’s icon library is a collection of pre-designed icons that can be used to enhance the user interface of an application. This pre-designed icons are set of base64 formatted font icons. Utilizing this icon library can make it simpler to create a cohesive, visually pleasing design for an application.

Referring icons in Angular application

Using the below approaches, the icons can be referenced in the Angular application.

npm package - Use the npm package to access icons.
CDN reference - Use the static web asset to access icons.

The npm package

All Syncfusion theme icons are shipped in the ej2-icons package, which is published on the npmjs.com public registry. This package contains both CSS and SCSS theme files for all themes.

Icons can be used from the npm package ej2-icons. To use the icons, install the npm package using the following command:

 npm install @syncfusion/ej2-icons

Refer to the following syntax to use icons in a Angular application:

[src/styles.css]

@import "../node_modules/@syncfusion/ej2-icons/styles/<theme_name>.css";

Example:

@import "../node_modules/@syncfusion/ej2-icons/styles/material.css";

CDN reference

All Syncfusion theme icons are available on the CDN. Instead of using a local resource on the server, use a cloud CDN to refer to the icons.

Make sure that the version of the icons in the URL matches the version of the Syncfusion Angular package. This will prevent compatibility issues and ensure that the correct version of the icons is loaded.

To use the icons from the CDN, refer to the icons by URLs in the application. This can be done by linking the icons in the HTML file by adding a link tag to the head section.

// Bootstrap5
<head>
    <link href="https://cdn.syncfusion.com/ej2/ej2-icons/styles/bootstrap5.css" rel="stylesheet"/>
</head>
//Material
<head>
    <link href="https://cdn.syncfusion.com/ej2/ej2-icons/styles/material.css" rel="stylesheet"/>
</head>

Steps to use icons library

Let’s create a Angular application using the following command:

For an introduction and configuration of the common specifications, see getting started with the Syncfusion Angular application.

Using icons directly in HTML element

The built-in Syncfusion icons can be rendered directly in the HTML element by defining the e-icons class, which contains the font-family and common properties of font icons, and defining the available icon’s class with the e- prefix.

The following steps explain the direct rendering of the Syncfusion icon in the HTML element.

Add the class name e-icons to the HTML element that needs to render the icon.
Add the icon class with corresponding icon content from the available icons. For example, the below code snippet represents the paste icon class.
```
 .e-paste:before{
     content:'\e355';
 }
```
Add e-icons and e-paste classes to the HTML element.
```
 <span class="e-icons e-paste"></span>
```
Add the CDN link reference of icons library in the ~index.html file.
```
 <link href="https://cdn.syncfusion.com/ej2/ej2-icons/styles/bootstrap5.css" rel="stylesheet" />
```
The below code snippet represents the complete example of icon usage.

app.component.ts
main.ts
import { NgModule } from '@angular/core'
import { BrowserModule } from '@angular/platform-browser'




import { Component, ViewChild } from '@angular/core';

@Component({
standalone: true,
  selector: 'app-root',
  template: `
    <div class="icon-bar">
      <span class="e-icons e-cut"></span>
      <span class="e-icons e-copy"></span>
      <span class="e-icons e-paste"></span>
    </div>
  `
})

export class AppComponent {
  
}
import { bootstrapApplication } from '@angular/platform-browser';
import { AppComponent } from './app.component';
import 'zone.js';
bootstrapApplication(AppComponent).catch((err) => console.error(err));

<button class="preview-sample-button" id="PreviewSampleButton-ptiu44hrbfjdb45mqec5mcwy5rcy7z7d" onclick="LoadPreviewSample('https://helpej2.syncfusion.com/angular/documentation/samples/common/icons',this.id);">Preview Sample</button><button class="stackblitz-button" id="StackBlitzButton-ptiu44hrbfjdb45mqec5mcwy5rcy7z7d" onclick="OpenSampleInStackBlitz('https://helpej2.syncfusion.com/angular/documentation/samples/common/icons');"><img class="stackblitz-icon" src="https://cdn.syncfusion.com/documentation/images/StackBlitz-icon.png"/><span class="stackblitz-text">Open in Stackblitz</span></button>

Icon size

The ej2-icons package offers options to display icons in different size modes. A user can use different icon sizes in their application based on touch or mouse mode. If the user is using touch mode, add e-large class to the element to make the icon easily interact, or add the e-small or e-medium class in mouse mode.

The pre-defined icon size is present in the available classes listed below.

e-small - Sets the icon size as 8px.
e-medium - Sets the icon size to 16px.

e-large - Sets the icon size to 24px.

Example:

  <span class="e-icons e-small e-search"></span>
  <span class="e-icons e-medium e-search"></span>
  <span class="e-icons e-large e-search"></span>

app.component.ts
main.ts
import { NgModule } from '@angular/core'
import { BrowserModule } from '@angular/platform-browser'




import { Component, ViewChild } from '@angular/core';
import { Animation } from '@syncfusion/ej2-base';

@Component({

standalone: true,
  selector: 'app-root',
  template: `
    <div>
      <p><b>Smaller Icons</b></p>
      <div class="small-icon-bar">
        <span class="e-icons e-small e-cut"></span>
        <span class="e-icons e-small e-copy"></span>
        <span class="e-icons e-small e-paste"></span>
      </div>
      <p><b>Medium Icons</b></p>
      <div class="medium-icon-bar">
        <span class="e-icons e-medium e-cut"></span>
        <span class="e-icons e-medium e-copy"></span>
        <span class="e-icons e-medium e-paste"></span>
      </div>
      <p><b>Larger Icons</b></p>
      <div class="large-icon-bar">
        <span class="e-icons e-large e-cut"></span>
        <span class="e-icons e-large e-copy"></span>
        <span class="e-icons e-large e-paste"></span>

Icon appearance customization

The Syncfusion Angular icons can be customized with custom color and size by overriding the e-icons class. Customizing the icons in the library can be useful for making the icons more visually appealing and fitting to the design of the application. For example, a user can change the color of an icon to match the color scheme of their application, or increase the size of an icon to make it more visible on smaller screens. It may also be useful for creating a consistent look and feel across different parts of the application. Overall, customizing the icons in the library can improve the overall user experience of the application.

main.ts
import { NgModule } from '@angular/core'
import { BrowserModule } from '@angular/platform-browser'




import { Component, ViewChild } from '@angular/core';
import { Animation } from '@syncfusion/ej2-base';

      <span class="e-icons e-paste"></span>
