[Theme: Catch Box] category page text align

hey guys. im running the catch box theme and in a category page, the post preview has the picture on the top left, and the text bellow the picture. what i want is the picture to stay at the same place (left) but have the preview text on the right of the picture. i know that some themes have this by default, but how can i change this in the catch box theme? ive spend tons of time by now searching for a solution but could not find any…
any feedback is highly apreciated
heres the link in case you want to see what i mean:
