Off and on for years I've needed to be able to add italics to captions. I still haven't found a solution. Here is what I have found:
-You can add italics to the entire caption via CSS, but that's not ideal because only part of the caption should be italicized and the CSS code only lets you italicize the entire caption.
-You can manually code the image, caption and drop-shadow box and produce the desired effect, but that requires hand-coding every image.
Therefore, no ideal solution is available. It seems absurd to me that after years of requesting this "feature" WordPress still doesn't allow code in the caption field. Unless I'm missing something?
