The first thing you need to do is create a Google Spreadsheet using the TimelineJS template. It’s then as simple as dropping a date, text, and links into the appropriate columns. When you’ve finished entering all of the details for your timeline you then go to the file menu and click on the ‘Publish to Web’. When the next window pops up just click ‘Start Publishing’. This will give you the URL to embed in your HTML file or WordPress post editor.
I think it’s pretty cool and a very easy way to create a timeline on your site. You can see below that I’ve given it a go. The one I’ve created here is on the British and Irish Lions rugby tour to Australia. You have the option to custom format the timeline but I’ve just kept mine to the default style. Give it a try and let me know what you think.
