I have embedded a Google Slide into my front page with links to different course components (see image). I keep getting a black box around the slide. I understand that this is due to the size of the embedded content, and I can go in and change the height and width and the box will disappear. However, it will reappear with different parameters on the screen (for instance, if I zoom in or out it will appear and disappear, if I hide  the course navigation window the black border disappears, but reappears when the navigation window is toggled back on). Is there a work-around for this?
