Editor's Notes
- http://developer.yahoo.com/performance/rules.html
- Delight the user with what’s available, and not moan about what isn’t or make the experience terrible for those without.
- Modify header. We have long had the opacity property, which is similar, but opacity forces all decendant elements to also become transparent and there is no way to fight it (except weird positional hacks <http://css-tricks.com/non-transparent-elements-inside-transparent-elements/> ) Cross-browser opacity <http://css-tricks.com/css-transparency-settings-for-all-broswers/> is also a bit sloppy. http://24ways.org, http://css-tricks.com/text-blocks-over-image, www.marcofolio.net/css/sweet_tabbed_navigation_using_css3.html Hue is derived from a degree on the color wheel: 0 & 360 being red, around 120 for the greens, 240 for the blues and everything else in between Saturation is a percentage: 0% being grayscale and 100% in full color Lightness is a percentage: 0% is dark, 50% the average and 100% the lightest
