Or how about dynamically drawing a diagonal line or swirl across the page?
I apologize for the lack of an example, but I'm sure you can imagine how much harder that would be in html and css then it is with a renderer that has bezier curves and lines as primitives.
What if I want to use html+css+js to
dynamically draw a 1024x1024 picture of a cat

Either way, well played, sir.
The OP said html+css+javascript, which I assume means html primitives like div and span with css and javascript sprinkled all over it. Canvas and svg exist a little bit outside of that ecosystem and I assumed the OP wasn't referring to that, because sure... with WebGL you can literally program anything into the browser. If someone used webGL as an example it would sort of render his question pointless.
