Using JavaScript to render to a canvas will work in all modern browsers, while maintaining (or even enhancing) the CSS's flexibility. I first thought the JavaScript solution would even be about the length of Moeed's CSS, but after writing it out my code's about 5x longer :(

edit: here's a jsfiddle of it in action http://jsfiddle.net/MftVp/

With jQuery I doubt it would be 5x longer.

jQuery doesn't provide anything that would make the above code shorter.

Firefox 5+ supports CSS3 animations and transforms with the -moz prefix. A quick replace all in pulse.css gets the animation working fine.

This effect can be realized on every JavaScript-supporting browser, or in fact any animated-.gif-supporting browser.

I think it was a proof-of-concept work.

I can't but I'd downvote this simply for not being cross browser compatible in some form

An idea can be interesting without being cross-browser. The author makes no claims about this being the defacto-enterprise-grade blinking dot.

Might be nice if the link title mentioned it, so save the rest of us the time.

I think the idea of a pulsating dot has been around long enough that it could have been implemented a bit more solid.
