btw, thanks maxlarin.
So,.rt-block {padding: 10px;margin-bottom: 0px;}
These affect the whole page, but reducing margin-bottom from 10px to 0px didn't mess things up, so this has helped tighten up overall look, which is what I wanted anyway. Reducing padding however, destroys the design.
So an improvement, but still would like to reduce the space by 15px or so.
Also, is there a margin-top? I noticed bottom gap is now smaller than top on one section. Perhaps I just need to reduce padding for <div class="quote">, not sure which of these numbers I would need to change?...quote-l {display: block;padding: 8px 10px 0px 36px;margin: 15px 0;}
.quote-r {display: block;padding: 0 10px 0 0;}
