thumbnail column layout

I’ve got the columns not lining up and the text below the thumbnails not going on to the next line and I’m a little confused what might be messing up the CSS. I switched my child theme to just plain old twenty twelve and still there, deactivated another YouTube and a Grid Column plugin, still there. Helllllp.
