Modern Device Dimensions for Chrome DevTools

These are modern “Emulated Devices” (a.k.a. responsive dimensions) for Chrome DevTools’ Mobile Device Viewport Mode.

They are specifically Apple devices, subtracting for recent Safari UI (as in window.innerWidth/Height), and cleverly sorted with some dark-arts unicode shenanigans. (This glitchy, unloved portion of the tools sorts lexicographically, because of course it would.) Ergonomics!

Note

Updated June 2025 with some notes from folks below! TL;DR: use Vibranium!

Basic Snake HTML and JavaScript Game

Snake is a fun game to make as it doesn't require a lot of code (less than 100 lines with all comments removed). This is a basic implementation of the snake game, but it's missing a few things intentionally and they're left as further exploration for the reader.

Further Exploration

Score
When the snake eats an apple, the score should increase by one. Use context.fillText() to display the score to the screen

The repository for the assignment is public and Github does not allow the creation of private forks for public repositories.

The correct way of creating a private frok by duplicating the repo is documented here.

For this assignment the commands are:

Create a bare clone of the repository. (This is temporary and will be removed so just do it wherever.)

git clone --bare [email protected]:usi-systems/easytrace.git
