Greetings,
I wanted to enhance a few of the bootstrap components - like the image below, I added the icons to help the student understand they should click on the section to expand it. I did this by loading an image into a page and then grabbing the URL - turns out that the path is user-specific somehow so my students get an error (no image is rendered) when they visit the same page.

.card-header .btn-link:after {

background-size: 30px 30px;
