Put in wrong code

Hi poeple, did something stupid.

I added some css to the page css from BB (not in the customizer.)

Now I cannot save or get to the css anymore, could somebody explain how to change this?
i tried bb savemode that didnt seem te work

I added:

button:not(:disabled), [type='button']:not(:disabled), [type='reset']:not(:disabled), [type='submit']:not(:disabled) {

cursor: pointer;

display: none;

}

really could use some help, wkr

thanks for the reply, however tried this yesterday because somebody on the facebook group had this solution to but; doesby work on the template only on modules unfortunatly.
bit thanks for trying wkr

somebody went into the database to remove this little peace off css. that helped and the wrong code is luckely removed.
wkr
