paper-fab ========= Material Design: Button `paper-fab` is a floating action button. It contains an image placed in the center and comes in two sizes: regular size and a smaller size by applying the attribute `mini`. When the user touches the button, a ripple effect emanates from the center of the button. You may import `iron-icons` to use with this element, or provide a URL to a custom icon. See `iron-iconset` for more information about how to use a custom icon set. Example: ```html
