is there a css editor to change my project background because i want to change mine to a better one
No, we don’t provide a css editor to change the editor theme styles.
is it possible to make one
I recently replied (and the answer was accepted) to a question like this.
You can use Stylish Addon to change how the editor looks. This adds a HTML
style tag in the header, if you use the CSS
!important keyword when changing colors it will force the css to change the color of the background to what you prefer.
