Please forgive me, as I am not too familiar with modifying the CSS code in WordPress. I copied your snippet to style.css right after the code labeled “Image Captions”. This seemed to move the text underneath the image, but the image is still not aligning with the text.
I’m trying to make the images (in the link of my original post) look like the ones found in https://protolounge.com/323/toorcamp-2012-day-2-talks-and-robots, but with captions.
(edit) I did click “Update File” and refreshed the page, just to make sure.
