It’s now super easy to add a “Share on Tumblr” button to any site.
Adding the basic Tumblr Button couldn’t be simpler. Just cut and paste the code and you’ll be off running. But the advanced options are where it gets interesting…
The Tumblr Button can give you complete control over how your content appears when shared on Tumblr. Not only does this mean specifying an excerpt or summary, but also deciding whether it appears as a Link, Quote, Photo, or Video Embed.
The appearance of the button is also completely customizable.
