Experience
Digital Business Card
http://codepen.io/chrisbolin/pen/regMgEThis project consists of a business card that can be "flipped" as the viewer scrolls down. Written in JavaScript using React in ES6, it allowed me to play with a few concepts:
• Single-source state. The entire state of the page is determined by a single variable: The vertical scroll position. Therefore, the whole application is literally "functional"—a function of this only variable. One of the entertaining consequences is that the entire process is reversible, allowing users to scroll up and down arbitrarily.
• DOM elements for visuals. I wanted to create visuals from simple DOM elements like divs and text that "felt" like Canvas or WebGL.
• Styling in JavaScript. The site's dynamic styling is driven by JavaScript, not CSS, using React's style property.
The code in context with CSS and HTML counterparts can be found in the above link.
