1. Comprehensive Image Alt Text
+
+ Every image on my website has been carefully evaluated and provided with appropriate alt text. I distinguish between:
+
+
+ -
+ Decorative images: Images that are purely decorative, such as the LaTeX tutorial thumbnail, have alt text that
+ indicates their decorative nature (e.g., "Decorative thumbnail showing LaTeX code and formatting example").
+
+ -
+ Informative images: Images that convey information, such as project screenshots, have detailed alt text
+ describing their content (e.g., "Screenshot of HRIStudio application showing the robot control dashboard on a laptop").
+
+
+
Implementation details: I implemented this by adding custom "imageAlt" properties to all projects
+ and "alts" arrays for travel items in my data structure, ensuring consistent image descriptions throughout the site.

2. Accessible Video Player
+
+ I developed a custom video player for the LaTeX tutorial with several accessibility features:
+
+
+ - Closed captions that can be toggled on/off
+ - Full transcript available with expandable details element
+ - Keyboard-accessible controls for play/pause, volume, and caption toggling
+ - ARIA labels for all controls to improve screen reader compatibility
+ - Video poster image with appropriate alt text
+
+
Implementation details: I created a custom AccessibleVideo component that wraps the HTML5 video element
+ with additional accessibility features, including captions integration, keyboard navigation, and proper ARIA attributes.
+
+
+
+
3. Semantic HTML and ARIA
+
+ My website uses semantic HTML throughout to ensure proper structure and meaning:
+
+
+ - Proper heading hierarchy (h1, h2, h3) for logical document structure
+ - Semantic elements like <nav>, <main>, <section>, and <article>
+ - ARIA attributes for components without native semantics
+ - Skip-to-content links for keyboard users
+
+
Implementation details: I audited all pages for proper heading structure and added semantic HTML elements. For
+ custom components like cards and badges, I ensured proper ARIA attributes were used to convey their purpose and state.
+
+
+
+
4. Color Contrast and Dark Mode
+
+ I carefully selected color choices on my website to ensure readability:
+
+
+ - All text meets WCAG AA contrast requirements (4.5:1 for normal text, 3:1 for large text)
+ - Dark mode support for users who prefer or require reduced brightness
+ - Color is never used as the sole means of conveying information
+ - Interactive elements have visual focus indicators that don't rely solely on color
+
+
Implementation details: I used the TailwindCSS color palette with careful consideration of contrast ratios.
+ The dark mode implementation respects user system preferences and provides consistent contrast ratios in both modes.
