silverlight stretching to 100% in Firefox...

An FAQ:

Setting the Silverlight plugin to width = 100% and height = 100% and then accessing plugin.content.ActualWidth works in IE, but doesn’t in Firefox. (ActualWidth/Height is always 0).
Using a fixed size (600,600) in firefox works fine however.

 

 

I had worked around it before, but not researched in-depth... 

 

Here is a solid answer from Peter Blois:

 

Firefox does not default the height to fill the page, IE does. To fix this I use the CSS:

html, body {

height: 100%;

      overflow: auto;

}

body {

      padding: 0;

      margin: 0;

}
