opening up the style.css on the helios, and searching for "borders" yep i know, general.. it comes up with 19 of them.. now you have to decide which ones you want, or not..
but this is the one you want.. .tborder
(warning, it will put borders around everything from below the menu for navigation

)
/* This is used on tables that should just have a border around them. */
.tborder
{
border-top: solid 1px #ffffff;
border-left: solid 1px #ffffff;
border-right: solid 1px #ffffff;
border-bottom: solid 1px #ffffff;
background-color : #000000;
padding: 0px;
}
see this example 1 and 2, in attachments
if you would like, change it to a red, instead of my white, FFFFFF or images :
background-image: url(images/pod/titlebg.gif);
changed to:
border-left-image: url(the url where it is.info);
now moving right along, Bloc used these images in this range for your red color:
pod-info-midright.gif etc., correct? now what if... you removed those images.. conselling out the code..?? or.. use those images as the t-border images instead? or make your own..
you just have to search for the file that contains the image coding.. hint: display, top of the beginning of the code..
