remove spacing below title (on sticky)

Hello,
I am wondering how to remove the spacing below and above the title on the stickies.
I already removed the text preview and could remove the title, too, if I wanted, but still there would remain a bit of white below the preview pictures.
I checked style.css and did not find it. I also did not find anything about it in this or other forums.

To show you which spacing I mean I uploaded a screenshot:

I found this part:

.twocol .entry-container {
padding:4.5%;

}

Here, the padding of the title can be changed but I did not find anything about that pacing below.

Does anyone know where to find it and how to change it?
It would be a great help!
