CSS Integration Examples

Ready-to-use code examples for implementing fonts in your projects

Basic @font-face Declaration

CSS
                @font-face {
  font-family: 'AMS Leafy';
  src: url('/fonts/ams-leafy.woff2') format('woff2'),
       url('/fonts/ams-leafy.woff') format('woff'),
       url('/fonts/ams-leafy.ttf') format('truetype');
  font-weight: normal;
  font-style: normal;
  font-display: swap;
}
              

Multiple Font Weights

CSS
                /* Regular Weight */
@font-face {
  font-family: 'AMS Rekha';
  src: url('/fonts/ams-rekha-regular.woff2') format('woff2');
  font-weight: 400;
  font-display: swap;
}

/* Bold Weight */
@font-face {
  font-family: 'AMS Rekha';
  src: url('/fonts/ams-rekha-bold.woff2') format('woff2');
  font-weight: 700;
  font-display: swap;
}
              

Using Fonts in CSS

CSS
                .hindi-text {
  font-family: 'AMS Leafy', 'Noto Sans Devanagari', sans-serif;
  font-size: 18px;
  line-height: 1.6;
  text-rendering: optimizeLegibility;
}

.heading {
  font-family: 'AMS Rekha', serif;
  font-weight: 700;
  font-size: 2rem;
}
              

Font Loading with JavaScript

JAVASCRIPT
                // Using Font Loading API
const font = new FontFace(
  'AMS Leafy',
  'url(/fonts/ams-leafy.woff2)',
  { weight: '400', style: 'normal' }
);

// Load and add to document
font.load().then((loadedFont) => {
  document.fonts.add(loadedFont);
  console.log('Font loaded successfully');
}).catch((error) => {
  console.error('Font loading failed:', error);
});
              

Preloading Fonts (HTML)

HTML
                <!-- Preload critical fonts -->
<link rel="preload"
      href="/fonts/ams-leafy.woff2"
      as="font"
      type="font/woff2"
      crossorigin>

<link rel="preload"
      href="/fonts/ams-rekha-bold.woff2"
      as="font"
      type="font/woff2"
      crossorigin>
              

React Font Integration

JAVASCRIPT
                // styles/fonts.css
@import url('./fonts/ams-leafy.css');

// App.jsx
import './styles/fonts.css';

function App() {
  return (
    <div style={{fontFamily: 'AMS Leafy, sans-serif'}}>
      <h1>नमस्ते दुनिया</h1>
      <p>Beautiful Hindi typography</p>
    </div>
  );
}
              

Performance Optimization

Best practices to ensure fast font loading and excellent user experience

Use font-display: swap

High Impact

Prevents invisible text during font load and shows fallback fonts immediately

font-display: swap;

Preload Critical Fonts

High Impact

Load essential fonts as early as possible to reduce render delays

<link rel="preload" href="font.woff2" as="font" type="font/woff2" crossorigin>

Font Subsetting

Medium Impact

Include only required characters to reduce file size

unicode-range: U+0900-097F; /* Devanagari */

Use WOFF2 Format

Medium Impact

Modern format with better compression than TTF/OTF

src: url('font.woff2') format('woff2');

Minimize Font Variations

Medium Impact

Load only necessary weights and styles to reduce requests

/* Load only 400 and 700 weights */

CDN Optimization

Low Impact

Serve fonts from CDN for better global performance

Cache-Control: public, max-age=31536000

Unicode Support & Character Sets

Understanding Unicode ranges for Hindi, Devanagari, and Indian language support

Devanagari (Hindi/Marathi)

256 characters
unicode-range: U+0900-097F;

Core Devanagari script for Hindi, Marathi, Sanskrit, and Nepali languages

Devanagari Extended

32 characters
unicode-range: U+A8E0-A8FF;

Extended Devanagari characters for additional language support

Latin Basic

128 characters
unicode-range: U+0000-007F;

Basic Latin characters for English text and numbers

Latin Extended-A

128 characters
unicode-range: U+0100-017F;

Extended Latin for European languages with diacritics

General Punctuation

112 characters
unicode-range: U+2000-206F;

Common punctuation marks and formatting characters

Font Subsetting Example

@font-face { font-family: 'AMS Hindi Subset'; src: url('/fonts/ams-hindi-subset.woff2') format('woff2'); unicode-range: U+0900-097F, U+0020-007F; /* Only Devanagari + Basic Latin characters */ font-display: swap; }

This example creates a subset containing only Devanagari and basic Latin characters, significantly reducing file size for Hindi-specific content.

Developer FAQ

Technical questions and answers for font implementation

What's the difference between self-hosting and using font services?
Self-hosting gives you complete control over font loading and performance, while services like Google Fonts offer convenience but less control. For Indian fonts not available on CDNs, self-hosting is typically required.
How do I handle fallback fonts for Hindi text?
Always specify fallback fonts that support Devanagari script. Use font stacks like: 'Custom Font', 'Noto Sans Devanagari', 'Mangal', sans-serif. This ensures text remains readable if custom fonts fail to load.
Why does my Hindi text look different across browsers?
Different browsers have varying levels of OpenType feature support and text rendering engines. Test across browsers and consider using web fonts with consistent rendering rather than relying on system fonts.
How can I optimize font loading for mobile users?
Use font-display: swap, preload critical fonts, implement font loading strategies, and consider font subsetting to include only necessary characters for your content.
What's the best way to handle multiple font weights?
Load only the weights you actually use. Define each weight separately in @font-face declarations and use font-weight in CSS to access them. This prevents loading unnecessary font files.
How do I ensure fonts work in older browsers?
Provide multiple font formats in your @font-face declaration, starting with WOFF2, then WOFF, then TTF. Include EOT format for IE8 and below if needed. Use font feature detection for advanced features.
