Thank you so much Shar!

I used that website and your resource, but I still have some small black lines on the sides after I used the Responsive Embedder:

I added &rm=minimal after the 3000 to get rid of the navigation bar below the slide and this is what I ended up with:

I got rid of the navigation bar, but there are still black lines on the bottom, top, and right side as well.

I wonder if this just has to do with the screen resolution and if changing the dimensions for height and width (along with an adjusted percentage for the container) would fix that? I also wonder if it will look like this on our students' chromebooks after we've tweaked all of this code! If their resolution is different than ours, will it adjust?

Thanks so much!
