how to center info on xfeed

Hi I'm using xfeed and was wondering how to center the info that is posted under the index page.

Right now the info is all positioned to the right.

I tried this::

.cardimgcrop {
background: #000;
margin: 0 0 12px 0;
position: relative;
min-height: 134px;
min-width: 200px;
}

didn't work ...

PS: attached is what it looks like right now. I want to center it. for each page "about gerard, acting career, discotheque ringleader"


Thank You
Moki
