1. Create your spreadsheet
Build a new Google Spreadsheet using the TimelineJS Template. Once you're done editing, publish the spreadsheet to the web (File > Publish to the Web > Start Publishing). Refer to Knight Lab's TimelineJS site for more information.
2. Enter your spreadsheet
Copy and paste your spreadsheet's URL here:
4. Use this css
Paste this into the HTML view of your timeline post in Chorus to override the Vox.com styles and make it look all sweet and verge-ified.
Note: Any changes you make to your spreadsheet should automatically update in the timeline. If you toggle back and forth between HTML and visual view, you will likely have to re-copy and paste the embed code into the HTML view.
