However, there are a couple of issues yet to be considered. First, what's the point on swapping style sheets if we cannot make the process reversible? And second, if we were able to turn on and off style sheets alternately in a single Web document, the change would be kept only until the next page request. If the user ever had the "bad" idea to click on any links, our carefully crafted technique to swap style sheets would be gone with the wind. Obviously, the whole process is stateless.
These issues should be efficiently addressed. Those reasons are good enough to head us directly to the last part of this series. In it, I'll be discussing and implementing some interesting approaches to change any number of styles sheets, and making that change persistent across several Web pages. Want to know more? Just stay tuned until the next article. The wait will be worth it!
