Make Navigation Menu with Overlay Effect use CSS3

Sedikit males juga sebenarnya memosting tentang menu Sudah kebanyakan yg mosting :d Karena menu yg satu ini memiliki sentuhan gaya sedikit unik, maka terpaksa deh Koben posting tutorial menu. Menu kali ini tidak akan terlihat sebelum di klik. Kalaupun muncul, si menu akan menutupi seluruh body template! Trick membuat menu dengan efek overlay full memakai atribut CSS3. Tricky toogle button teranyar full pakai CSS3. We are talking about pure css navigation with overlay effect b-)
