Thank you Mr. Goyal for your reply. I am surprised that with all the options developed for CSS that there is no way to specify an image width based on column width. Apparently, you can use (1) aspect ratio, (2) absolute width in px, em, %, vw , etc or (3) portrait/landscape. Portrait/landscape is just shorthand form for either/or aspect ratio, but no options relate to actual column width. I compromise by testing em. Here is another pair of examples. Best regards, Pop
