I’ve been tryign to bring up a single page application for a course project. Here’s what I like to remember:

• Bootstrap is a simple library that offers plenty of easy to use and nice looking components. I ended up using the navbar.
• JQuery has a slim version that doesn’t have the .ajax function. The “Getting Started” page for bootstrap refers to slim version.
• If you want some interactive maps on your web site, consider looking into datamaps.
• You can have variables in CSS and do math with them.
• Use viewport when you’re setting sizes.
