resize and align youtube video

I’m trying to figure out how to resize and realign youtube videos, in a way that text will wrap around the video.

So far, all I’ve been able to come up with that works is:

<p class="alignright">
<iframe src="https://www.youtube.com/embed/W9OcZTJsZsw" width="280" height="157" frameborder="0" allowfullscreen="allowfullscreen"></iframe>
</p>

It seems like there must be a better/easier way that I’m just not finding.
