- `paper-ripple` provides a visual effect that other paper elements can
- use to simulate a rippling effect emanating from the point of contact. The
- effect can be visualized as a concentric circle with motion.
-
- Example:
-
- <paper-ripple></paper-ripple>
-
- `paper-ripple` listens to "down" and "up" events so it would display ripple
- effect when touches on it. You can also defeat the default behavior and
- manually route the down and up actions to the ripple element. Note that it is
- important if you call downAction() you will have to make sure to call upAction()
- so that `paper-ripple` would end the animation loop.
-
- Example:
-
- <paper-ripple id="ripple" style="pointer-events: none;"></paper-ripple>
- ...
- downAction: function(e) {
- this.$.ripple.downAction({x: e.x, y: e.y});
- },
- upAction: function(e) {
- this.$.ripple.upAction();
- }
-
- Styling ripple effect:
-
- Use CSS color property to style the ripple:
-
- paper-ripple {
- color: #4285f4;
- }
-
- Note that CSS color property is inherited so it is not required to set it on
- the `paper-ripple` element directly.
-
- By default, the ripple is centered on the point of contact. Apply `recenteringTouch`
- class to have the ripple grow toward the center of its container.
-
- <paper-ripple class="recenteringTouch"></paper-ripple>
-
- Apply `circle` class to make the rippling effect within a circle.
-
- <paper-ripple class="circle"></paper-ripple>
