How did Facebook change the font of Javascript console output?

Question

How is this done? Is there a way to inspect/debug the console?

When does that happen? I opened the JS console on Mac Chrome 36 while at facebook.com, I didn't see it. — Barmar, Jun 10 '14 at 21:25

Console API Reference:

Nice example of using the console.log:

console.log("%cUser %s has %d points", "color:orange; background:blue; font-size: 16pt", 'User', 100);

Just paste it into the console :)
