Set up your default styles to be appropriate for EPUB readers. Then add JavaScript:

Code:

if (typeOf(navigator.epubReadingSystem) == "undefined") {
    /* It's a browser.  Add a new CSS stylesheet element dynamically. */
}

Readers that support only EPUB 2 won't load the JavaScript. Readers that support EPUB 3 and JavaScript will have an appropriate object there. So if you get into the body of that if statement, the content is being shown by a web browser.
