Boxed Xanga Entries, Background opacity Options

[deadsouls]

I was wondering if anyone knew a code to put to the boxed xanga code that makes the background of each box half transparent? is that possible?

this is the code i have for boxing my entries

CODE

<!-- begin code provided by createblog.com -->
<style type="text/css">
table.blogbody {
border: 1px solid #cccccc;}
</style>
<!-- end code provided by createblog.com -->

so i put the alpha opacity inside the table.blogbody, and made the table background set to white but when i do that, it makes the text dissapear. it is really still there, but for some reason it changes the text to the exact same color as the background and then makes it half opac.

CODE

<!-- begin code provided by createblog.com -->
<style type="text/css">
table.blogbody {
filter: alpha (opacity=50);
background-color: ffffff;
border: 1px solid #cccccc;}
</style>
<!-- end code provided by createblog.com -->

how do you fix this?
