Imitate Flickr and Digg's pagination styles

Recently, there's a new project, and it's also a good opportunity to do some refactoring and upgrades on the accumulated work from the past. I'll write about the code aspects later when I have more time to sit down and focus. These couple of days, there's a requirement that came up, which involves改造 an existing pagination tag, especially in terms of its styling. The styles in the old tag are already quite outdated.
