jStyler 介绍
This is a cookie based style switcher. Once a stylesheet is selected, it will
use that stylesheet until the cookie is removed. This stylesheet switcher
supports multiple amount of stylesheets, so sky’s the limit.
This stylesheet switcher also supports the use of default stylesheets that
will not be switched out when the switcher is activated. For example, you may
have a global css reset file you would like to use for all stylesheets. For
more information on how this works, view the demo.
