Space between textblocks – cannot remove it!?

Hi All

On my site https://www.yoke.dk you’ll see a list of projects presented with text and pictures. Between the textblocks and the pictures you’ll see a black space. This space between the elements I really wanna change, but I don’t know how to?

On my WP edit page I’ve tried putting in text and pictures with as little space between them as I can. But it doesn’t seem to matter what I do here.

I’m not sure if this is something that I should change in my stylesheet? I’ve posted it below.

Hop you can help me.
– Jesper
