I'm a web designer and developer. I'm the co-founder of CodePen, a playground for front-end web development. It’s a social development environment for front end designers and developers. I ran the site CSS-Tricks from 2007 - 2022. Along with Dave Rupert, I'm the co-host of a podcast called ShopTalk, a show about (you guessed it), building websites.
I've spoken at events and given workshops all over the world. I've also written three books: The Greatest CSS Tricks Vol. I, Practical SVG, and Digging Into WordPress.
