demos

Some one-off demos that needed hosting :)

• Offscreen canvas - OffscreenCanvas is a canvas that can be used in workers!
• Resize events for DOM elements - a Custom Element class mixin that uses ResizeObserver to know when its size changes. Basically, onresize handlers for DOM!
• CSS overscroll-behavior chatbox - shows how to use CSS overscroll-behavior to prevent the mobile browser pull-to-refresh effect and also contain scroll events within a chat window component.
• Create a video file from images - turn a list of png images into a .webm video using no dependencies and only web platform features.
• CSS position: sticky event - fire an event when elements begin/stop sticking.
• Material Design Playground
