This is a website I coded using
Bootstrap. It is a prototype for an e-commerce site that sells pocket knives and related products. (I'm a fan of nice pocket knives.) It has seven pages, four CSS files, is fully responsive, makes use of animations, and includes some JavaScript. The demo video shows how the website would be navigated and how the various media breakpoints react. The video is about four-and-a-half minutes long, so you may want to grab a snack and a beverage.
