I'll teach you:
First never leave a blank style format inside
ex:
.style {
}
To fix your block:
Open style.css
Put or change to:
table td {
margin: 0px;
padding: 0px;
vertical-align: top;
}
td#leftcolumn th {
margin: 0px;
padding: 0px;
}
The code:
margin: 0px;
padding: 0px;
It's telling and forcing the XOOPS theme to minimize the gap and space.
-------------------------------------
If you are talking about other gap like outside of the block.
You need to fix up the theme.html file.
