Aku mau share tutorial buat ngasi animasi di kursor. aku kasi bayangan dikit, intinya, setelah masukin script dibawah ini, kursor kamu akan ada "buntutnya" yaitu bola-bola yang bisa memantul. berhubung aku g da blog "korban", aku g bisa ngasi SS contohnya. Buat temen-temen yang uda nyoba, bisa kasi SS di komentar y... buat referensi yang laen.... :P
1. Buka blogger.com trus login
2. Masuk dashbord, trus pilih "design" blog yang mau kamu pasang animasi ini.
3. klik "edit HTML"
4. centang "Expand Widget Templates"
5. trus cari tag </body> (biar gampang, tekan ctrl + f)
6. Copy semua script yang di kolom bawah ni tepat "DIATAS" atau "SEBELUM" tag </body>
