CSS to reduce line spacing between header and paragraph

Please see the attached image. The line spacing between my header font and my paragraph font is WAY too large.
There seems to be no way to tighten it up, because if I try a soft-return (shift+return) it forces the fonts to all be the same selection, i.e. all header or all paragraph.

I have dozens of these kinds of text treatments, in my site, so I'd like a way to solve this efficiently. Some CSS?

Thanks!

It looks like you solved with this code?

.sqsrte-large {
    margin-top: -25px;
    margin-bottom: 0px;
}
