Alpha Transparency
Posted on 2004-04-06
Hi,
I'm using the following code to creat a transparency for certain cells of a table:
<table background="img/home_bg.jp
<tr>
<td height="250" bgcolor="#ffffff" style="filter: alpha(opacity=50); -moz-opacity: 0.50;"><div align="center">alpha transparency applied</div></td>
</tr>
<tr> <td height="250"><div align="center">no alpha transparency applied </div></td></tr>
</table>
The problem is that the text is also afflicted with the transparency. How can I make the background use the transparency, but not the text?

I never used alpha transparency filters, but I would try to override opacity style in the inner <DIV>:
<table background="img/home_bg.jp
<tr>
<td height="250" bgcolor="#ffffff" style="filter: alpha(opacity=50); -moz-opacity: 0.50;">
<div align="center" style="filter: alpha(opacity=100); -moz-opacity: 1.00;">alpha transparency applied</div>
</td>
</tr>
<tr> <td height="250"><div align="center">no alpha transparency applied </div></td></tr>
</table>
<table background="img/home_bg.jp
<tr>
<td height="250" bgcolor="#ffffff" style="filter: alpha(opacity=50); -moz-opacity: 0.50;">
<div align="center" style="filter: alpha(opacity=100); -moz-opacity: 1.00;">alpha transparency applied</div>
</td>
</tr>
<tr> <td height="250"><div align="center">no alpha transparency applied </div></td></tr>
</table>
you are applying the transparency to the whole table cell...you just want the background color of the table cell to use the filter?
I just posted this a couple of days ago - it may be what you need:

Just put a layer with a high z-index on top in the cell and adjust the relative position.
<table background="img/home_bg.jp
<tr><td>
<div style="height:250px;backgr
<div style="height:250px;z-inde
alpha transparency applied</div></td>
</tr>
<tr> <td height="250"><div align="center">no alpha transparency applied </div></td></tr>
</table>

<tr><td>

<div style="height:250px;z-inde

</tr>
<tr> <td height="250"><div align="center">no alpha transparency applied </div></td></tr>

That's pretty much what I was suggesting :-)
<style type="text/css">
table { background-image: url('color1.gif'); }
#trans { position:relative; left:0; top:0; z-index:1; width:100%; height:100%; background-color:#FFF; filter:alpha(opacity='40')
</style>
<table>
<tr>
<td width="100" height="100">
<div style="position:relative; width:100%; height:100%;">
<div id="trans"></div>
<div style="position:absolute; left:0; top:0; z-index:2;">
<p>MY TEXT</p>
<p><a href="#">My Link</a></p>
</div>
</div>
</td>
<td width="100" height="100"> </td>
</tr>
</table>
<style type="text/css">
table { background-image: url('color1.gif'); }
#trans { position:relative; left:0; top:0; z-index:1; width:100%; height:100%; background-color:#FFF; filter:alpha(opacity='40')
</style>
<table>
<tr>
<td width="100" height="100">
<div style="position:relative; width:100%; height:100%;">
<div id="trans"></div>
<div style="position:absolute; left:0; top:0; z-index:2;">
<p>MY TEXT</p>
<p><a href="#">My Link</a></p>
</div>
</div>
</td>
<td width="100" height="100"> </td>
</tr>
</table>
Glad we could help. Thanks for the A. :^)

Oh yeah that... The result of many misspent hours... days... weeks. It's gotten too easy.
I thought I left on of my trademark typos in a color value.
A million is nice but getting cert number 6 (web languages) is bigger. There are fewer experts with 6 then there are million pointers.

There is a slightly easier way ...
I have a cell (which is a TH) ...
<style>
.MaintTHError
{
border-style : none;
border-color : #FF0000;
background-color : #FF0000;
filter : alpha(opacity='15');
}
.MaintSPANErrorLabel
{
position: relative;
left: 0px;
top: 0px;
text-align: center;
}
</style>
<th class="MaintTHError"><span
That's it!
I use this to give the cell (which is a header for a row) a transaparent red background when there is an error in that row. The page background stills shows through and you do not need to worry about sizing anything. I've only tried it with a single line of text.
Hope this is of use to you all!
Regards,
Richard Quadling.
