Nicolas Gallagher is sharing a creative way on creating good-looking speech bubbles with CSS3.
There are no images or JavaScript in the implementations but uses the :before and/or :after pseudo-elements to produce basic shapes.
The HTML remains semantic however we should remember that CSS3 is not fully supported by all major browsers & we may again require JavaScript to add this support (like IE7.js).
Compatibility: Browsers With CSS3 Support
