Floating an ad box in the middle of an article

I've been trying to figure out how to float an ad in the middle of my articles, without having to actually put code in between article text.

Here's a picture of a mockup for more info:



See how the article flows around the ad box on the top and bottom? From what I'm reading about floats, I have to break it up, like

Article text blah blah blah lots of stuff here....
<div class="adbox">
Ad Link 1
Ad Link 2
etc.
</div>
the rest of my article continues here...

Code (markup):

Is there any way to do it without sectioning the article?

Thanks in advance.

 

You could place the box at the top of the content element then give it a lot of top margin.

 

and position absolute

 

That would make there be quite a bit of white space above the box, since the text doesn't fill in inside the margin.

 

nest the ad div inside the content div, give it margins and float it left.
