Öncelikle doğru yere açtım mı bilemedim. Aşağıdaki kod java gibi geldi ondan buraya ekledim.
Şimdi efendim aşağıdaki kod da tuşa başında sayfa full ekran oluyor ben bunu "Kullanıcı siteye girdiğinde mouse ile herhangi bir tıklama yapınca" full ekran olsun istiyorum. Bunu yapabilecek ücretli ücretsiz biri varsa mesaj bekliyorum. Teşekkürler
