For the Extra, and any other plane, the key is a combination of proper speed and proper descent rate. The ideal landing is as already described, get the plane within inches (2-3, not 12-24) of the ground and keep adding up elevator until it won't fly any more.

In windy conditions, especially when gusty, I tend to land hot. Doing so requires very careful control of the decent rate so it is almost zero when the wheels touch the ground. If you can do this it won't bounce and the drag will immediately start slowing the plane. It's also critical to not immediately feed in large amounts of up elevator, or the plane may take off again, with possibly disasterous results. This is much easier on grass than a hard surface.

If you fly planes with trike gear, you can reduce the tendency of the plane to bounce by adjusting the height of the nose gear so the plane sits a little nose down. When the plane is on all 3 wheels, it's not going to want to lift off. This also can help your takeoffs. The plane will not takeoff until you decide to add up elevator.
