Sorry for misleading you. The image is a photoshop mockup.
Although I have a strong background in HTML, Javascript, css, etc., today is literally the first time I've touched Canvas. I'm poking around trying to figure out how to edit the css to turn of the page margins and remove the pre-inserted title. The image is an altered screenshot of a sample page.
Regardless of whether I do that screen with an embedded image or with HTML code, I find myself hindered by the predefined margins.
I am a programmer for a large school district. This is our first year with Canvas. I'm evaluating this for some self-paced coursework. 🙂
