Web accessibility is the practice of building websites and apps that people with disabilities can perceive, understand, navigate, and use.
It improves inclusion, usability, legal compliance, and overall product quality for everyone.
WCAG stands for Web Content Accessibility Guidelines, the main standard used to evaluate digital accessibility.
Content should be Perceivable, Operable, Understandable, and Robust.
It means all key functionality can be used without a mouse, typically through Tab, Shift+Tab, Enter, Space, and arrow keys.
Visible focus helps keyboard users know which interactive element is currently active.
Using built-in elements like button, nav, main, and label to convey meaning and behavior correctly.
Buttons come with keyboard support, focus behavior, and assistive-technology semantics by default.
Alternative text is a short description of an image used by screen readers and shown when images fail to load.
Decorative images can use empty alt text so assistive technologies skip them.
Color contrast is the visual difference between text and background, which must be strong enough for readable content.
Some users cannot perceive color differences reliably, so status and meaning should also be communicated with text or icons.
