title: How do I take a screenshot of DOM element using intern js?
body: <p>I'm using <a href="https://theintern.github.io/" rel="nofollow">intern.js</a> to test a web app. I can execute tests and create screenshots when they fail. I want to create a screenshot for specific element in order to do some CSS regression testing using tools like <a href="https://huddle.github.io/Resemble.js/" rel="nofollow">resemble.js</a>. Is it possible? How can I do? Thank you!</p>
