CSS Icons

Icons enhance user interfaces by visually representing actions, categories, or brand elements. CSS can style icon fonts (like Font Awesome) or SVG icons to fit your design. Icons help users navigate and understand content more easily.

Key Topics

  • Using Icon Fonts
  • SVG Icons
  • Color and Size Adjustments
  • Accessibility Considerations

Using Icon Fonts

Icon fonts are easy to integrate. Include the font’s stylesheet, then insert icons as pseudo-elements or <i> tags. Resize them with font-size and color them with color.

SVG Icons

SVGs are scalable and retain quality at any size. You can style them with CSS, changing fill colors, adding hover effects, or animations.

Accessibility Considerations

Provide alternative text or aria-labels for icons that convey meaning. Users relying on screen readers must understand the icon’s purpose.

<!-- Example with Font Awesome -->
<link rel="stylesheet" href="https://cdnjs.cloudflare.com/ajax/libs/font-awesome/6.0.0-beta3/css/all.min.css" />
<style>
    .icon {
        color: blue;
        font-size: 24px;
    }
</style>
<i class="fas fa-home icon" aria-hidden="true"></i> Home

Explanation: The icon is styled using standard CSS properties, just like text. The aria attributes help screen readers interpret the icon’s meaning.

Key Takeaways

  • Enhancement: Icons improve navigation and visual appeal.
  • Scalability: Icon fonts and SVGs scale easily without losing quality.
  • Accessibility: Provide text equivalents to ensure inclusivity.
