Vertically position iframe inside paragraph

I am trying to be clever and position a FaceBook Like button iframe inside a sentence but it aligns oddly, see screengrab below.

I'm sure I'm being dense but without styling the iframe as a block element how do I re-position it?

I tried display:inline-block but it didn't respond to margin settin开发者_如何学编程gs. I also tried increasing the paragraph's line-height to match the iframe but that didn't help.

Wrap it in a DIV and adjust margin-top on the DIV.

vertical-align:middle did the trick.
