I have put the borders of the modules in sidebar-r hidden.
I have my own border: "itemblock" in custom.css. Therefore it is not necessary so many borders.
The code that I have put in custom.css is the following:
.jmoddiv.jmodinside {
border: hidden!Important;
}
.module-ct ul:last-child, .module-ct p:last-child, .moduletable ul:last-child, .moduletable p:last-child {
border: hidden!Important;
}
All borders are hidden when hovering with the mouse.
Please refine it if necessary.
