Narrative:
While departing 24L behind another carrier's B777; the aircraft encountered wake turbulence at approximately 1;200 ft MSL. The aircraft rolled approximately 20 to 30 degrees and experienced moderate turbulence. The event caused concern from our flight attendants and passengers. I believe the preceding B777 was airborne before we crossed the hold short line to hold on the runway. There was sufficient time for a couple of aircraft to cross the runway downfield before we took off. We reported the wake turbulence to the departure controller and she stated that the preceding B777 was eight miles south of our position. I am submitting this report because I believe we had proper separation from the preceding B777 and the aircraft still encountered wake turbulence.
