This is as good as it gets: NPR’s annual roundup of the best books of the past year is an ideal one-page app.
Above: Mobile screens. Below: Desktop, with one book selected (third from left). Fully responsive design, using Bootstrap.
Above: Click any book and get this modal overlay, which you can also use to simply browse all titles. In a single-page app, you never leave the original Web page.
At the bottom of the HTML source, you can see the entire dataset for all the books in the form of a minified JSON object.
The HTML is super-clean and readable. If you have used Bootstrap, you can understand it completely.
