Hey! My name is Michaël Vanderheyden
aka. Th3S4mur41

I'm a passionate web developer dedicated to crafting accessible and user-friendly interfaces that make a difference. I believe that every user—regardless of abilities or context—should experience seamless, intuitive digital interactions. My love for clean code and exploring the latest HTML and CSS features fuels my drive for innovation. With a background in martial arts, I bring the same discipline, respect, and commitment to my work, ensuring high-quality, future-proof solutions.

The web is my dojo

This website is my personal training ground. Beyond being a home for my blog, it serves as a laboratory where I experiment with the latest web techniques—specifically pushing the boundaries of modern HTML and CSS.

Help me improve

Since this site is a playground for experimentation, things might occasionally break in unexpected ways. If you find a bug or an accessibility barrier, please report it via GitHub issues. Your feedback helps me sharpen my craft and ensures a better experience for everyone.
