Drop Out
The element gives a tiny hop, then falls off the bottom of the screen, speeding up under gravity and tipping a little as it goes.

How to use it
- Paste the snippet just before
</head>. - Add
data-drop-outto any element.
Options
Add any of these attributes to the same element.
data-tilt | How far it tips as it falls, in degrees. A looping demo tips the other way each time. Default 8. |
data-hop | How far it lifts before it falls, in px. 0 for none. Default 10. |
data-distance | Fall this many px, fading out, instead of leaving the screen. |
data-duration | How long the fall takes. Default 750 ms. |
data-delay | How long it stays in view before it drops. Default 1200 ms. |
data-loop | Fade back in, hold and drop out again. |
data-hold | How long it stays between exits, when looping. Default 1400 ms. |
It leaves past the edge of the nearest container that clips its overflow (overflow: hidden or clip), or of the window. Put it in a clipping wrapper, or give the page overflow-x: clip, so it can’t make the page scroll sideways on its way out. It ends hidden (visibility: hidden) but still taking up its space. To play it when you choose, leave the attribute off and call animacious.dropOut(el).

// to stay between exits when looping, default 1400).
