How do you make 2 LED's fade (PWM) consecutively on an Arduino?

I want 2 LED's to fade one after another but i can't figure out the code yet. 

Both starting bright ?
Try this

analogWrite(led1,255);
analogWrite(led2,255);
for (int bright=255;bright>0;bright--)
analogWrite(led1,bright);
for (int bright=255;bright>0;bright--)
analogWrite(led2,bright);
