Vertical Timeline

From our sponsor: Market smarter with Mailchimp's automated messaging tools.

This is a simple responsive timeline with alternating colors for the labels. An icon font is used for the icons in the timeline waypoints and some example media queries show how to adjust the timeline for smaller screens. The main structure of the timeline is an unordered list.
