Hello,
1) Just add a negative margin to the element in the custom.css file:
.s5_is_wrap {
margin-bottom: -10px !important;}
2) Add this to the custom.css file
#s5_breadcrumb_wrap .moduletable {
border: 1px solid #000000;
padding-right: 5px;
padding-left: 5px;}
3) This would require custom programming changes.
4) Please review our Firebug Tutorial here:
http://www.youtube.com/watch?v=4kmZ9uQcA_cIt explains how to identify elements and change pre-exisiting background calls.
5) Adding or modifying module suffix's would require custom programming. We list all the available styles here:
