RGBA color values are IE9, Firefox3 +, Chrome, Safari, and Opera10 + support.
RGBA color values are RGB color values extending alpha channel - the specified object transparency.
RGBA color values specified: RGBA (red, green, blue, alpha). Alpha parameter is a number between 0.0 (fully transparent) and 1.0 (fully opaque) parameters.
IE9, Firefox, Chrome, Safari, and Opera 10+. Support HSL color values.
HSL representative of hue, saturation, and brightness - Use color cylindrical coordinates.
HSL color values specified: HSL (hue, saturation, brightness).
Hue is a degree on the color wheel (from 0-360) -0 (or 360) is red, 120 green, 240 blue. Saturation is a percentage; 0% and 100% of the mean gray shadow, full color. Brightness is also a percentage; 0% is black, 100% is white.
HSLA color values are IE9, Firefox3 +, Chrome, Safari, and Opera10 +. Support.
HSLA color values are an extension of HSL color values with an alpha channel - the transparency of the specified object.
Specifies HSLA color values: HSLA (hue, saturation, brightness, α), α is the opacity Alpha parameter definition. Alpha parameter is a number between 0.0 (fully transparent) and 1.0 (fully opaque) parameters.
