更改用AJAX加载的元素的CSS

I have two webpages on my website: a welcome page with links to other pages, and a bio page (and some other pages, irrelevant atm). The bio page has a "cloud" effect so that the background scrolls slower than the content. When you click the link to the bio page, the welcome page uses $.load() to load the content of the bio page into a div with id="bodyContent", and the link tag to my css is changed so that it now points to the css from the bio. The javascript is also loaded so that the scrolling functions work.
