Can I do this with CSS: I want to display only a portion of an image, in effect to mask the rest of the image. For instance, if I have an image 1200px by 1600px, I want to show only a slice of it, say 450px by 100px. I can imagine how, if a "window" can be created, it could be located by coordinates within the larger image itself. But I can't figure out whether and how this "peek" of something larger might be done.
Thanks for any suggestions.
