from saturday 4/14 - tried out a different viewer for pdf rendering. Currently it's responsive to browser size or other elements on the page...work in progress
added animation and change instructor lecture back to pdf.js - <canvas> tag - instead of using viewer.js with <iframe> tag. If I can set up a previous and next page link to change content pages without using viewer.js, it would make things more customizable and flexible to manipulate content/code
