In a page I'm working on I want a slideshow to be "floating" in the middle of text like what happens when we set align="right" (or left) to an img tag.

If I add a slideshow block then a content block, the slideshow block shows totally above the content. I tried adding "float: left" in the additional CSS for the slideshow block but that doesn't seem to work - it makes the slideshow block completely disappear. Could someone point out a way to do this?

Thanks
