I know this isn't strictly code related, but i know that vscode is used in the github copilot website. However, how do i get my ide and copilot suggestions to look like that?
Very hard to tell the exact theme they used there, it might not even exist.
Anyway, the font is this one: Cascadia Code Web, it comes with installation instructions and here it is described how to install it in vs code
For the theme colors, I am not quite sure as I said, but it does look similar to the github dark color theme, just install the extension and press Ctrl+K, Ctrl+T and select Github dark from the dropdown
It's not the exact look, but hope it helps
