Web accessibility means creating websites that everyone can use, regardless of their abilities or disabilities. This includes people who are blind, deaf, have motor impairments, cognitive disabilities, or use assistive technologies like screen readers.
Blind, low vision, color blind users rely on screen readers and proper contrast
Users with limited mobility need keyboard navigation and large click targets
Good accessibility improves usability for all users, including on mobile

Why Semantic HTML Matters
<span class="semantic-badge"><article></span>
</h2>
<p>
Semantic HTML elements clearly describe their meaning to both the browser and the developer.
Elements like <article>, <nav>, <header>, and <footer> provide
structure that assistive technologies can understand and navigate.
</p>
<p>
Screen readers use these landmarks to help users jump to different sections of your page quickly.
This is similar to how you might use a table of contents in a book.

Many countries require websites to be accessible (ADA, Section 508, WCAG compliance). Non-compliance can result in lawsuits.
15% of the world's population has some form of disability. That's over 1 billion potential users.
Semantic HTML and proper structure help search engines understand and rank your content better.
Accessibility features like keyboard navigation and clear labels benefit all users, especially on mobile.

Color contrast (4.5:1)
