What is accessibility?
Accessibility ensures that digital products are usable by everyone, including people with disabilities. This includes physical, sensory, cognitive, and neurological disabilities.
Web accessibility follows established guidelines like WCAG (Web Content Accessibility Guidelines) to ensure that websites are perceivable, operable, understandable, and robust.
Example 2: Native HTML Details/Summary (Multiple)
How do I navigate with a keyboard?
Use the Tab key to move focus between interactive elements. Shift+Tab moves focus backward. Press Enter or Space to activate buttons and toggles.
What is a screen reader?
A screen reader is assistive technology that reads aloud the text and interactive elements on a web page. Common screen readers include NVDA, JAWS, and VoiceOver.

Color contrast refers to the difference in brightness between text and its background. Sufficient contrast helps people with low vision or color blindness read and understand content.
WCAG 2.2 Level AA requires a contrast ratio of at least 4.5:1 for normal text and 3:1 for large text.

WCAG stands for Web Content Accessibility Guidelines. These are international standards developed by the World Wide Web Consortium (W3C) to ensure web content is accessible to everyone.
You can test accessibility by using automated tools like axe, WAVE, or Lighthouse, as well as manual testing with assistive technologies like screen readers and keyboard navigation.
User testing with people who have disabilities provides invaluable real-world feedback.
