Reduce whitespace?

Make sure you’re working in a child theme or some type of CSS file protected from theme updates. In either of those, the following CSS should get you off to a good start.

.home #content-full,
.home #widgets .col-300,
.home #widgets .col-300 p:last-child {
	margin-bottom: 0;
}

thnx. that did it. ??

No problem!
