CSS Floats and DIVs

[objecterror]

I have read a tutorial on div's in css, that and floats which seem to be pretty specific, i understand the basics but not much else.
What i'am looking to do exactly though is, by using a layout from a website is pretty simple.
Since tables/frames are messy, i want to use a float as a frame, basically a user clicks a link on my webpage, and instead of the entire page reloading, just a specified portion or div on the website opens the page.
I'am a bit confused though, do i make the second webpage first and then on the main page some how direct the link to a div on the front page? or should i post the code for additional reference?

It will be a completely separate page, but all most the same as your index page.

"index.html"
"page1.html"
"page2.html"
all link to "name.css"

You can not <ahref-"#"> <div> as if it were a <frame>....sorry.
So completely second page...not a page that that "directs" through <div>.

Hope it helps a bit.

Cheers,
