  • "Opacity" refers to transparency; the lesser the opacity of an image, the more transparent it is.

Syntax

We use CSS to define the initial degree of opacity in Firefox:

<IMG style="-moz-opacity:0.5" src="test.gif">

Valid range of values for -moz.opacity is from 0 to 1, where lesser equates to more transparency.

Usage

  • Quick opacity change onMouseover:
<IMG style="-moz-opacity:0.6" src="alta.gif" onMouseover="this.style.MozOpacity=1" onMouseout="this.style.MozOpacity=0.6">
