styling

Hi
This is great plugin, many thanks.
I have a bit of the problem with styling
I can style it in css but I was trying to create the two containers (with bootstrap) for the image and for text so they are distinctively separated.
the text at the moment moves under the image and I would like to be able to have 3 line title of post next to the image.
I was looking in the index.php but could not really find where the containers are. Could you please suggest where to do it?

kind regards
Mike
