Decorative Images

This lesson explains Decorative Images in web accessibility with clear examples, practical use cases, and implementation best practices.

Decorative Images Overview

Decorative images enhance the visual appearance of a webpage but do not provide meaningful information or functionality. Since these images do not contribute to the page's content, screen readers should ignore them to prevent unnecessary announcements and improve the browsing experience for users with visual impairments.

The recommended approach for decorative images is to use an empty alt="" attribute. This tells assistive technologies to skip the image while allowing sighted users to enjoy its visual presentation. Proper handling of decorative images improves accessibility, usability, and compliance with WCAG guidelines.

Feature	Benefit
Empty Alt Attribute	Prevents screen readers from announcing decorative images.
Cleaner Navigation	Reduces unnecessary interruptions.
WCAG Compliance	Meets accessibility recommendations for decorative content.
User Experience	Keeps screen reader output focused on meaningful content.
SEO	Avoids misleading alternative text.
Best Practice	Only describe images that provide information or functionality.

Decorative Image Example

<img
  src="divider.svg"
  alt="">

<img
  src="background-pattern.png"
  alt="">

Both images are decorative and do not communicate important information. Using alt="" ensures screen readers ignore them, creating a cleaner and more accessible experience.

Which Images Are Decorative?

Decorative images are included only to improve visual design. If removing an image does not affect the meaning or functionality of the page, it is likely decorative and should use an empty alt attribute.

Image Type	Decorative?	Recommended Alt
Background Pattern	Yes	alt=""
Visual Divider	Yes	alt=""
Decorative Icon	Yes	alt=""
Company Logo	No	Describe the organization.
Product Image	No	Describe the product.
Button Icon	No	Describe the button action.

Decorative Image Best Practices
