Step-by-Step Guide to Making Sliders Accessible

Not all WordPress slider plugins are created equal. Look for plugins that prioritize accessibility, such as:

Each image in your slider should have alt text to describe its content for visually impaired users.

Accessible sliders must be navigable via keyboard. Ensure users can move between slides using the Tab and arrow keys.

Tabto navigate to the slider. - Use the left and right arrow keys to change slides.

| Element | Color Contrast Ratio | Compliant |
|---|---|---|
| Slide Title | 4.5:1 | Yes |
| Navigation Arrows | 3:1 | No |
Step 6: Enable ARIA Roles and Labels
Use ARIA roles and labels to define the slider’s structure and functionality. Example:
<div role="region" aria-label="Featured Content Slider">
<div role="group" aria-roledescription="slide" aria-label="Slide 1 of 5">
<img src="example.jpg" alt="Description of slide 1">
</div>
</div>
Step 7: Test with Assistive Technologies
