Whew! Converting my old HTML webpages into XHTML has proved to be very hard and laborious. So far I've only been able to convert the FAQ page! From now on, I will put little stickers that say "W3C | XHTML 1.0 √" under the navbars of each page that I've converted. The pages have been validated by the W3C (X)HTML validator. I'm still working on the main page.
Also, I've decided to make a general background color, so the website wouldn't be so confusing with so many flashy colors. I've already changed the main page, so see if you like the color. I also made the navbars transparent, so they can match the background.
Happy Chinese New Year!
