This document is a work in progress and is subject to change.
Summary
- Firefox allows you to use coding to manipulate the opacity of an image.
- "Opacity" refers to transparency; the lesser the opacity of an image, the more transparent it is.
| Initial Value: | 1(opaque) |
| Applies to | all elements |
| Inherited: | No |
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">
Mozilla Recommended Values
