Have you ever tried to create awesome/different things with CSS?. Try this one. Here I’d like to share an awesome tutorial that focuses on step-based CSS3 keyframe animation, along with the usage of the animation-play-state property to start/stop/reset the stopwatch.
This great CSS script developed by Ruby On Tails. According to the developer, no images or JavaScript are used in the stopwatch logic/display. The only image used is the background wood pattern for beautification purpose and all the logics are implemented in CSS
