→Fun with -moz-opacity
*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.
<table border="0">
<tr>
<td><b>ApplicabilityInitial Value:</b></td><td>The background-repeat property can be used for all CSS elements.1(opaque)</td>
</tr>
<tr>
<td><b>[http://developer.mozilla.org/en/docs/CSS:%40media#Media_groups Media Group:]Applies to</b></td><td>Visualall elements</td>
</tr>
<tr>
== Syntax ==
Opacity:1.0 shows you all of the image; Without any filters applied the opacity of an image is 1.0 (fully opaque).
We use CSS to define the initial degree of opacity in Firefox:
<pre>
<IMG style="-moz-opacity:0.6" src="alta.gif" onMouseover="this.style.MozOpacity=1" onMouseout="this.style.MozOpacity=0.6">
</pre>
*For CSS opacity to work in the browser it must have some placement specified. Mozilla recommends that we use float:left; and position:relative; to work in Mozilla Firefox. The opacity code for simply displaying an image is more straightforward.
<pre>
<span style="float:left;filter:alpha(opacity=25);-moz-opacity:.25;opacity:.25;"><img src="v90.gif" width="50" height="50"></span>
</pre>

To make your page more attractive, you can do something like this:
[[Image:Fun stuff.png]]
<pre>
<div style="color:black;width:150px;background:white;filter:alpha(opacity=50);-moz-opacity:.50;
opacity:.50;float:right;margin-top:10px;margin-bottom:10px;margin-left:10px;
font-family:Verdana, Arial, Helvetica,Georgia;font-size: 28px;line-height:26px; text-align: right;">
...this will look like some of the
<b>pullquotes or subtitles we see</b>
in
<span style="width:150px;padding-bottom:10px;float:right;text-align:left;color:black;background:white;
filter:alpha(opacity=25);-moz-opacity:.25;opacity:.25;">magazine<b>layout...</b></span>
</div>
</pre>
