How to Use Google Fonts

Method 1: Link Tag (Recommended)

Add these lines to your HTML <head> section. This method allows for better performance through preconnect hints.

<link rel="preconnect" href="https://fonts.googleapis.com">
<link rel="preconnect" href="https://fonts.gstatic.com" crossorigin>
<link href="https://fonts.googleapis.com/css2?family=Roboto&family=Montserrat&display=swap" rel="stylesheet">

Method 2: @import in CSS

Add this line at the top of your CSS file. This method keeps all font definitions in your CSS.

@import url('https://fonts.googleapis.com/css2?family=Roboto&family=Montserrat&display=swap');

Method 3: JavaScript API (Advanced)

For more control over font loading, you can use the Google Fonts JavaScript API.

<script src="https://ajax.googleapis.com/ajax/libs/webfont/1.6.26/webfont.js"></script>
<script>
  WebFont.load({
    google: {
      families: ['Roboto', 'Montserrat']
    }
  });
</script>

Best Practices for Google Fonts

Performance Optimization

Use rel="preconnect" for faster DNS resolution
Only load the weights and styles you actually need
Use the &display=swap parameter to avoid FOIT (Flash of Invisible Text)
Consider self-hosting fonts if you need more control over caching
Limit the number of font families (2-3 per page is ideal)

Typography Best Practices

Choose complementary font pairs (serif + sans-serif often works well)
Establish a clear visual hierarchy with font weights and sizes
Ensure sufficient contrast between text and background
Use appropriate line height for readability (1.5-1.6 for body text)
Test your font choices on different devices and screen sizes

Accessibility Considerations

Ensure text has a minimum contrast ratio of 4.5:1 for normal text
Avoid using fonts that are too light or thin for body text
Use relative units (em, rem) for font sizes to support zooming
Provide adequate letter spacing for uppercase text
Test your font choices with screen readers and other assistive technologies
