I'm a total newbie. I'm building a site. https://edrl.berkeley.edu/content/kinemathics . The site includes images, such as photographs, with text captions under them. Recently (?!), some of these text captions have broken and slipped, with the first words appearing to the left of the image and the rest still below it where they should be. I've tried monkeying with the margin width, but that doesn't seem to be the problem. Any clues?
