SVG Accessibility: Making Vector Graphics Inclusive

Why SVG Accessibility Matters

Over 1 billion people worldwide have disabilities. Making your SVG graphics accessible ensures everyone can understand and interact with your content. It's also often a legal requirement.

Accessibility Fundamentals

Understanding Assistive Technologies

How people access SVGs:

WCAG Guidelines for Images

Core requirements:

WCAG 2.1 Requirements:
Non-text content needs alternatives
Color not sole conveyor of info
Sufficient color contrast
Resizable without loss
Focusable elements keyboard accessible

SVG Accessibility Patterns

Decorative SVGs

For purely visual elements:

When to use:

Informative SVGs

For meaningful graphics:

When to use:

Complex SVGs

For detailed information:

ARIA Attributes for SVG

Essential Attributes

role="img"           
role="graphics-document"  

aria-label="..."     
aria-labelledby="..." 
aria-describedby="..." 

aria-hidden="true"   
focusable="false"    

Title and Desc Elements

Native SVG accessibility:

Interactive SVG Accessibility

Focusable Elements

Make interactive parts accessible:

Focus Indicators

Visible focus states:

svg a:focus,
svg [tabindex]:focus {
  outline: 2px solid #0066cc;
  outline-offset: 2px;
}

Keyboard Navigation

Ensure keyboard access:

svgElement.addEventListener('keydown', (e) => {
  if (e.key === 'Enter' || e.key === ' ') {
    // Activate element
  }
});

Color Accessibility

Contrast Requirements

WCAG contrast ratios:

Minimum Requirements:
Text: 4.5:1 (normal), 3:1 (large)
Graphics: 3:1 against background
UI components: 3:1

Testing Contrast

Tools for verification:

Color Independence

Don't rely on color alone:

Icon Accessibility

Icon Buttons

Icon with Text

  
  Save Document

Standalone Icons

Animation Accessibility

Respecting Preferences

@media (prefers-reduced-motion: reduce) {
  svg * {
    animation: none !important;
    transition: none !important;
  }
}

Pause Controls

  Pause Animation
