Embeddable timelines make it easy to syndicate any public Twitter timeline to your website with one line of code.
Just like timelines on twitter.com, embeddable timelines are interactive and enable your visitors to reply, Retweet, and favorite Tweets directly from your pages. Users can expand Tweets to see Cards inline, as well as Retweet and favorite counts. An integrated Tweet box encourages users to respond or start new conversations, and the option to auto-expand media brings photos front and center.
