Behind the scenes
2:03How are web animations turned into videos?
A scene is a function of time: Chromium captures it frame by frame, ffmpeg encodes the video and mixes in the narration.
2:23How does a browser render a page?
From HTML and CSS bytes to pixels: DOM, CSSOM, render tree, layout, paint and compositing.
2:40From typing a URL to seeing the page
DNS, TCP and TLS, a static frontend served from a CDN, one call to a Go API, and the final render.
