I've noticed a problem I have with images in my posts: they seem to go unnoticed to my CSS.
For example, I have a span tag that is adding a 100px margin to the top of itself under the last paragraph in each post. http://tinyurl.com/chbqyrz
But when an image is present the span tag seems to ignore the image as part of the paragraph content. There is no 100px margin created: http://tinyurl.com/btkt2lw
I'd usually say this is a CSS problem... but I think it may be a WP problem. Any thoughts?
