CSS Browser Selector is a very small javascript with just one line which empower CSS selectors. It gives you the ability to write specific CSS code for each operating system and each browser.
EXAMPLE
The color of this box will change on different os/browsers:
- Internet Explorer – yellow
- Internet Explorer 7 – orange
- Gecko Engine on Windows (Firefox, Mozilla, Camino) – red
- Gecko Engine on Linux (Firefox, Mozilla, Camino) – pink
- Gecko Engine on Other OS (Firefox, Mozilla, Camino) – gray
- Opera – green
- Konqueror – blue
- Safari – black
- Chrome – cyan
If the box is white, and you are using one of browsers above, something is wrong :-/
Help us in this case!
