are all salts originated from halogen?

I know that when halogens (group 7) react with metal, it becomes salt. but are all salts originated from halogen?
A better definition of a salt for gcse chemistry is an acid which has lost its hydrogen. Since all acids contain hydrogen when they react they lose their hydrogen and it is replaced by a metal, you form a salt.

There are some examples here of neutralisation reactions to produce salts

but its a similar story with say metal and acid reactions.
