how browser works code example

Example: browser

is a UI (like curl or wget) that downloads (or reads from cache)
	.html(structure) XML nested DOM elements
	.css(style) rules target selectors=>elements => computed styles 
	.js(function) messes it all up 
     calculates layout layers boxes repaintable (video, animation)
      composits a page partially in the viewport using standards 	https://www.w3.org/standards/)
      with http (not ftp) 									  		https://en.wikipedia.org/wiki/Category:Application_layer_protocols)
	  and may store a variety of information (data, history, passwords)
CHROME a UI (bars, buttons) <= key, mouse, voice, image inputs
	uses chromium/blink an "rendering engine" that parses html=>DOM => computed styles
		uses V8(interprets, compiles, optimizes javascript to machine code)
has EXTENSIONS
has DEVTOOLS
has STORAGE
runs natively (not in a browser :)
