Reply To: [Solved] Purpose of '#' before a property (not ID)

[Paulie_D]

As far as I know..nothing..except disable it. It’s short form of commenting it out.

Browsers will ignore a property that does not start with a ‘recognised’ character.

It’s possible someone was trying to comment out the property temporarily.
