Accessibility for Loading Animations

/* Always respect reduced motion preference */
@media (prefers-reduced-motion: reduce) {
  .spinner,
  .dots-loader span,
  .progress-bar::before,
  .progress-bar::after,
  .skeleton {
    animation: none;
  }

  /* Provide a static alternative */
  .skeleton {
    background: #f0f0f0;
  }
}

/* Screen reader announcement for loading state */
<div role="status" aria-live="polite" aria-label="Loading...">
  <div class="spinner" aria-hidden="true"></div>
</div>

Loader Types Reference

• Spinner: best for short, indeterminate waits (button clicks, form submissions)
• Progress bar: best for longer operations where progress can be measured
• Skeleton: best for content loading (feeds, cards, lists) — reduces perceived wait time
• Dots: friendly, playful — good for chat apps and casual interfaces
• Pulse: subtle — good for status indicators and background processes

The CSS Loader Generator on TechConverter.me creates accessible, performant loading animations with complete HTML and CSS output. Choose your loader style, customize colors and size, and copy the code directly into your project.
