A small preloader I made as a learning experience.
Add a link to the loader.css file in the head of the html document.
<divclass="rainbow"><divclass="rainbow-container"><divclass="rainbow-color red"></div><divclass="rainbow-color orange"></div><divclass="rainbow-color yellow"></div><divclass="rainbow-color green"></div><divclass="rainbow-color blue"></div><divclass="rainbow-color indigo"></div><divclass="rainbow-color violet"></div></div></div>
