Different link colors

Try then:

.column_left_bottom div.moduletable, .column_right_bottom div.moduletable, .column_left_bottom div.moduletable h3, .column_right_bottom div.moduletable h3, .column_left_bottom div.moduletable h3 span, .column_right_bottom div.moduletable h3 span {

margin: 0!important;
}

Sorry the code just merged the modules due to margin 0 but there was no centering of the headline

headline?

For example "DBBL News" in the left column

Add this:

.column_left_bottom > .moduletable > *{
padding:10px;
}

code had no impact. Headline DBBL news still not centered. Any other idea?
