Firefox

Transparency: the ‘opacity’ property in Firefox
Name: opacity
Value: <alphavalue> | inherit
Initial: 1
Applies to: all elements
Inherited: no
Percentages: N/A
Media: visual
Computed value: The same as the specified value after clipping the <alphavalue> to the range [0.0,1.0].
- <alphavalue>
- Syntactically a <number>.
The uniform opacity setting to be applied across an entire object.
Any values outside the range 0.0 (fully transparent) to 1.0 (fully opaque) will be clamped to this range.If the object is a container element, then the effect is as if the contents of the container element were blended against the current background using a mask where the value of each pixel of the mask is <alphavalue>.
