If I decide to write a simple game both text and graphical (2d) what libraries would I use? (Assume we are using a HTML5 compatible browser)

The main things I can think of

• Rendering text on screen
• Animating sprites (using images/css)
• Input (capturing the arrow keys and getting relative mouse positions)
• Perhaps some preloading resource or dynamically loading resources and choosing order
• Sound (but I am unsure how important this will be to me at first). Perhaps with mixing and chaining sounds or looping forever until stop.
• Networking (low priority) to connect a user to another or to continuously GET data without multiple request (I know this exist but I don't know how easy it is to setup or use. But this isn't important to me. Its for the question).
