How to make content-block inline?

I'm rather new to CSS and can't seem to figure out how to make my blocks inline.

I have a block (from organic groups "Group Details") that I would like displayed inline instead of block. I thought if I went down to: /* Content-block region */

and placed in there:

.content-block .block {
  display: inline;
  line-height: 1em;
  text-align: right;
}
 

but no luck. Any ideas? Thank you
