im learning Dammit by blink-182 acoustic.. not sure about one of the chords

#1
i know its c/g G Am F, and if you mouse over chords in a tab it shows the finger positions. well for the F chord there is like a bar that goes through all the strings.
so its like the bar through the strings then 2nd finger on 2nd fret of G, 4th finger on third fret of D and 3rd finger on the third fret of A. i guess my question is what the hell am i supose to play for that bar down the strings.?

It's called a bar chord. You're probably gonna use alot of them over time. The bar is just where you bar your index finger over the strings.
