Instead of:
input:not(disabled)not:[type="submit"]:focus {}
Use:
input:not([disabled]):not([type="submit"]):focus {}
disabled is an attribute so it needs the brackets, and you seem to have mixed up/missing colons and parentheses on the :not() selector.

One thing to note: I may be wrong, but I don't think disabled inputs can normally receive focus, so that part may be redundant.
Alternatively, use :enabled
input:enabled:not([type="submit"]):focus { /* styles here */ }
Again, I can't think of a case where disabled input can receive focus, so it seems unnecessary.
