I did this in the templates which is easier if you have multiple styles:
In template BLOG, find:
Code:
<!-- Description -->
<if condition="$show['description']">
<div id="blog_description">$description</div>
</if>
<!-- End Description -->
Replace with:
Code:
<!-- Description -->
<if condition="$show['description']">
<div id="blog_description" class="tborder" style="padding: $stylevar[cellspacing]px"><div class="alt2" style="padding: $stylevar[cellpadding]px">$description</div></div>
</if>
<!-- End Description -->
I'm not sure if doing that with two DIVs is ideal, however as we're avoiding tables now I am not sure of any other way. Works in Firefox, Opera and IE so it can't be THAT bad.
