Excelsior Cinema is a simple introductory HTML-CSS-JavaScript project that is a website for a cinema. On this, one can view trailers and descriptions of movies that are 'now showing' as well as 'coming soon'. It also has a ticket booking functionality and a Google Maps integration. One can select their preferred seats, which will then become unavailable for selection the next time they try to book the same show. They can also navigate to the correct location using the embedded Google map.
