Angular Theme in Syncfusion Components

Optimized CSS Files

Syncfusion components provide two size modes for each theme: normal and bigger. By default, the normal size mode is applied, granting a standard look suitable for all devices. The bigger size mode enhances interactions, visibility, and user experience by enlarging UI components.

The bigger size mode is optimal for projects requiring enlarged display, whereas the normal size suits applications maintaining default appearances.

See below for a Button component comparison in both size modes:

bigger-sized-button

Each theme includes both normal and bigger sizes, increasing overall file size. To enhance performance, Syncfusion offers optimized theme files (e.g., fluent2-lite.css), which contain only normal size mode styles. These reduce file size, improving load times and application performance, especially when the bigger mode is not needed.

Refer to the comparison for theme file sizes:

Theme Name Default Theme Size Optimized Theme Size
Fluent 2 3.97 MB 2.96 MB

Installation

Syncfusion Angular UI themes can be included in your application by four different methods:

Install via NPM

Themes come as both individual and combined CSS files. Use the @syncfusion/ej2 npm package for combined CSS files, with individual files stored in the component repository’s style folder. Both CSS and SCSS files are provided in ej2 npm packages.

To install combined CSS files, run:

 npm install @syncfusion/ej2

CDN Direct Referral

Instead of local resources, use a cloud CDN to reference theme style sheets.

Syncfusion Angular Themes are available via CDN. Ensure the URL version matches your Syncfusion Angular Package to avoid compatibility issues.

<head>
    <link href="https://cdn.syncfusion.com/ej2/<version>/<theme_name>.css" rel="stylesheet"/>
</head>

For optimized CSS files, use:

<head>
    <link href="https://cdn.syncfusion.com/ej2/<version>/<theme_name>-lite.css" rel="stylesheet"/>
</head>

Using Precompiled CSS and SCSS File

Precompiled CSS

Precompiled signifies minified and optimized CSS.

Syncfusion Angular UI theme includes a precompiled CSS file encompassing styles for all Syncfusion components.

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

To refer to all components SCSS:

@import "ej2/<theme_name>.scss";

Individual themes are obtainable from individual package or ej2 package.

To refer to an individual component from an individual package:

@import "ej2-buttons/button/<theme_name>.scss";

Referring All Components Optimized CSS File

For optimized CSS files from the @syncfusion/ej2 package:

@import "@syncfusion/ej2/<theme_name>-lite.css";
/* or */
@import "@syncfusion/ej2/<theme_name>-lite.scss";

Example:

@import "@syncfusion/ej2/fluent2-lite.css";
/* or */
@import "@syncfusion/ej2/fluent2-lite.scss";

Referring Individual Component Optimized CSS File

For individual component’s optimized CSS from individual packages:

@import "<dependent-package>/styles/<theme_name>-lite.css";
/* or */
@import "<dependent-package>/styles/<theme_name>-lite.scss";

Example:

@import "@syncfusion/ej2-buttons/styles/fluent2-lite.css";
/* or */
@import "@syncfusion/ej2-buttons/styles/fluent2-lite.scss";

Advantages of Individual Components Theme

  • Reduces page load time
  • Decreases bundle size
  • Avoids unused CSS

Compiling Themes from SCSS Source File

The Syncfusion Angular UI theme includes SCSS file compilation. Refer to Compiling SCSS file for more information.
