Should I still use the <embed> element inside of my <object> elements when adding rich media? I'm trying to put together a personal "Development Tips Resource" and I skipped out on the <embed> because I honestly don't know when it was needed and if it still is.

P.S. I understand I can embed with javascript... just want to have both methods in the resource.

You can. The object tag isn't supported in some popular web browsers, so that's a plus.

Example to display a video :

<object width="500px" height="300px">
	
<param name="movie" value="http://www.youtube.com/v/gJfpLKhSjJs&amp;fs=1" />
<param name="allowFullScreen" value="true" />
<param name="wmode" value="opaque" />

<embed src="http://www.youtube.com/v/gJfpLKhSjJs&amp;fs=1" type="application/x-shockwave-flash" allowfullscreen="true" wmode="opaque" width="500" height="300" />

</object>

PS. HTML elements are everything from the start tag to the end tag,
