</html>Created animated wireframes using CSS and GiphyCapture (https://itunes.apple.com/us/app/gifgrabber/id668208984?mt=12). Example:

Stick animation.html, phone.png and animation.png in the same folder. animation.png is your exported wireframe and should be 320 pixels wide. Image assets:
https://designaction.org/gists/animation.png (example wireframe)
https://designaction.org/gists/phone.png
Open animation.html in your web browser. You can edit the CSS depending on your wireframe; this example uses five steps of animation, and includes an animation for each finger tap. To record the wireframe as a GIF, position a GiphyCapture window over your browser, hit Record, and refresh your browser to start the animation. You can edit the image to remove the initial few seconds.
