Lightbox Modal Image Gallery

Firstly, https://www.w3schools.com is a great tutorial site for learning tons of front end things. Secondly, I came across a curious little bug when trying to apply css styling to a lightbox. Some of it was not applying correctly. The issue was narrowed down to bootstrap css creating the conflict. If the link to it was removed everything looked fine. Thankfully I didn't need all the components that usually are incorporated with a slideshow that displays thumbnails. Upon removal of that the issue went away. But the fact still remains that the source of the issue may have come from a conflict between screen sizes and margin allowance. Food for thought.
