You don't state which type of link you are tying to change, and there are a number of different types and the HTML each of they produces can be different:
Markup based link [[Next Passage]]
link macro based link (link: "Next Passage")[(goto: "Next Passage")]
link-goto macro based link (link-goto: "Next Passage", "Next Passage")
click macro based link Next Passage (click: "Next Passage")[(goto: "Next Passage")]
named tag plus click macro based link |thehook>[Next Passage]
(click: ?thehook)[(goto: "Next Passage")]
The following CSS will change the link text of all the above link types to look the same as the rest of the passage's text, even if you change the look of the overall passage text. It should be placed within your Story Styesheet area:
warning: this will mean that the Reader will need to hunt for the links if you don't give them some other way of identifying them, which could cause the Reader to become confused or annoyed if they can't find any / all of them.
