The Solar System, Rendered in CSS and HTML
A web developer named Alex Giron has created a working model of the solar system using only web standards.
It’s fully animated — though Alex takes advantage of some new CSS 3 features (border-radius, transforms and animations) and utilizes the -webkit prefix, so you’ll need to view it in Safari or Chrome to see the planets move around the sun.
Firefox and Opera users won’t see the animations, just a static CSS layout. But the hover events work, so you can mouse over each planet and learn the story of each celestial body. And yes, he included Pluto.
Here’s Alex’s blog post that includes a walk-through of the code.
