Annotator

Anime.js is a lightweight JavaScript animation library with a simple, yet powerful API. It works with CSS properties, SVG, DOM attributes, and JavaScript Objects. Follow through animations made easy. Anime's built-in staggering system makes complex follow-through and overlapping animations simple. It can be used on both timings and properties. Animate multiple CSS transforms properties with different timings simultaneously on a single HTML element. Play, pause, control, reverse and trigger events in sync using the complete built-in callbacks and controls functions. Anime.js works with anything web. CSS, SVG, DOM attributes and JavaScript Objects, animate everything with a single unified API. Staggering allows you to animate multiple elements with follow-through and overlapping action. Animation keyframes are defined using an Array, within the keyframes property. Each keyframe duration will be equal to the animation's total duration divided by the number of keyframes.

Bideo.js is a JS library that makes it super easy to add fullscreen background videos. Fullscreen HTML5 background video for the web. Want to play a video in the background of a container or body itself? This plugin will help you do exactly that. The video element in use will automatically adapt to the container's dimensions. It will also resize as the browser window resizes. The plugin doesn't support any overlay as it is easy to implement that with plain HTML/CSS in your code. Video might take a few seconds to load, especially because the sources are added via JS which is something you'll load after the DOM's loading. Until then, you may want to show a video cover, which will be the same as the first frame or the video (or some other image). The support for this is not in the plugin as it's fairly simple to achieve this via just HTML/CSS (just like overlays).
