My WordPress site includes the full article in its RSS feed. This includes the text of the post and basic formatting. It also includes post images and their captions.
The problem is that my captions are not formatted. They appear below my images, but they look like plain text. This makes it hard for a reader to see that they are associated with the preceding image.
How can I change the formatting of the image captions in an RSS feed reader? I'd like to make the captions italic or to use a gray color to distinguish it from the other text.
