Presuming the content that you're trying to put in the div is from your own site, you need to change your mindset around. You don't "target" a piece of content into a box anymore. What you do is provide an entire web page with the new content in that div. So the link you click on to cause this (e.g. maybe from your navigation) should just be a standard <a href="newpage.html"> kind of link, and newpage.html would have the right stuff in the right place.
Thank you for that.
How do you click a link in one div tag area and have it put a page in another div tag area ?
So is the "page" you want to display a page of your own development, on your own site? Or is it a page from some other web site. If it's another web site, I agree with Charles, use an iframe for it. But if it's your own site, you should not use an iframe, you should just link to the page itself as I mentioned above.
It doesn't "put it in another div area", that's the point. Make two pages. Page 1 looks like what you're thinking now is your page (some navigation, some content). Page 2 looks a lot like it, has the sane navigation, and some other content (that corresponds to what you're wanting to be this ""other content in your div"). So both those pages are *complete* web pages with headers, navigation and content. Then you link the navigation from page 1 to the *entire* page 2, not just point it into some div.
