Quick Start
Install and Apply a Theme
Step 1: Install Syncfusion Angular Package and theme package
npm install @syncfusion/ej2-angular-buttons@latest @syncfusion/ej2-tailwind3-theme@latest --save
Step 2: Import Theme CSS
Option 1: Import from npm (Recommended)
/* src/styles.css */
@import "../node_modules/@syncfusion/ej2-tailwind3-theme/styles/button/index.css";
Option 2: Use CDN
To find your installed version:
npm list @syncfusion/ej2-angular-buttons
Then use the matching CDN version:
<!-- angular.json - Add to styles array -->
"styles": [
"https://cdn.syncfusion.com/ej2/33.1.44/tailwind3.css"
]
⚠️ Important: The CDN version MUST match your installed npm package version to avoid style and rendering issues.
Note: Using npm imports (Option 1) is recommended as it automatically keeps CSS and JavaScript versions in sync.
Common Patterns
Pattern 1: Apply Dark Mode Globally
import { Component, OnInit } from '@angular/core';
@Component({
selector: 'app-root',
template: `
<div>
<ejs-checkbox
label="Enable Dark Mode"
[checked]="isDarkMode"
(change)="handleDarkModeToggle($event)">
</ejs-checkbox>
<ejs-button cssClass="e-primary">Sample Button</ejs-button>
</div>
`
})
export class AppComponent {
isDarkMode = false;
handleDarkModeToggle(event: any): void {
this.isDarkMode = event.checked ?? false;
if (this.isDarkMode) {
document.body.classList.add('e-dark-mode');
} else {
document.body.classList.remove('e-dark-mode');
}
}
}
Pattern 2: Customize Primary Color with CSS Variables
For Fluent 2 Theme:
/* src/styles.css */
:root {
--color-sf-primary: #ff6b35; /* Custom orange */
}
For Material 3 Theme (uses RGB values):
/* src/styles.css */
:root {
--color-sf-primary: 255, 107, 53; /* RGB: Custom orange */
}
Pattern 3: Enable Touch Mode Globally
<!-- index.html -->
<body class="e-bigger">
<app-root></app-root>
</body>
Or per-component:
<ejs-button cssClass="e-bigger">Touch-Friendly Button</ejs-button>
Pattern 4: Use Optimized CSS for Faster Loading
/* src/styles.css - Lite version without bigger mode styles */
@import "@syncfusion/ej2-tailwind3-theme/styles/tailwind3-lite.css";
Pattern 5: Use Icons from Syncfusion Library
Install icons package:
You can install either the icons package or the theme package:
npm install @syncfusion/ej2-icons@latest
/* or */
npm install @syncfusion/ej2-tailwind3-theme@latest
Import icon styles:
/* src/styles.css */
/* Syncfusion theme package icon styles */
@import "../node_modules/@syncfusion/ej2-tailwind3-theme/styles/icons/tailwind3.css";
/* or */
/* Syncfusion components package icon styles */
@import "../node_modules/@syncfusion/ej2-icons/styles/tailwind3.css";
Use icons in components:
<span class="e-icons e-cut"></span>
<span class="e-icons e-medium e-copy"></span>
<span class="e-icons e-large e-paste"></span>
