Cara Buat Efek "Matrix"

Simple Matrix Effect Using Javascript

Hai sobat blogger :D, ada yang aneh gak dari gambar itu? :3 yap, itu bukan gambar tapi script yang mimin temuin hehe :D Penasaran kan gimana caranya? :3 oke, cekidot
Nah, sebelum mulai ada baiknya kalian ngerti dulu deh apa itu HTML, CSS, sama JavaScript. Mau belajar cepet tanpa guru? cekidot guys :D Oke, mimin asumsikan kalian udah ngerti ya? YA? IYA?! :3 oke, lanjut. Sekarang buka notepad(++ kalau ada). Nah, buat dokumen baru terus ketik (atau copas aja deh. Kecuali kalau kalian sanggup :3) script ini :

1:  <style type="text/css">  
2:  .matrix { font-family:Lucida Console, Courier, Monotype; font-size:10pt; text-align:center; width:10px; padding:0px; margin:0px;}  
3:  </style>  
4:  <script language="JavaScript" type="text/javascript">  
5:  var rows=5; // harus ganjil  
6:  var speed=50; // kecil lebih cepat  
7:  var reveal=2; // antara 0 sampai 2. Lebih besar, lebih cepat text tampil  
8:  var effectalign="center"

Nah, kalau ente udah copy ntu script diatas, klik save as, ganti extensionya jadi all type, *apa aja*.html. Atau bagi kalian para blogger atau web designer yang lagi cari ide monggo :3 NB : Warna Merah Berarti Bebas Di-Edit *Sumber+Demo*
