Styling your Chrome OS Crosh shell is actually really easy.
- Create a custom CSS theme using the example script here as an example.
- Host it online, perhaps on Github pages? ;) (It didn't seem to work when hosted locally with a file:/// prefix ¯\(ツ)/¯)
- Get Crosh if you haven't already [Chrome Store]
- Open up the Crosh options by pressing the search key, finding this icon and pressing Options.
- Paste the link of the css file into the bottom box that says 'user-css'. It will now load that file locally so you do not need to keep hosting the css file, or have an internet connection at all.
Done. :D
Recommended things to try:
letter-spacing: -0.5px; // or any other size
text-shadow: 0.5px 0.5px 0 rgb(84, 84, 84);
Have fun :)
