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.
