1. GIỚI THIỆU CODE HIỆU ỨNG TUYẾT RƠI BLOGSPOT
Code hiệu ứng tuyết rơi mình đã test trên blog cho thấy nó rất nhẹ và nổi bật.
Phía bên dưới đây mình có 2 phiên bản code hiệu ứng. Một bản là JavaScript và bản còn lại là CSS.
2. CÁCH SỬ DỤNG CODE HIỆU ỨNG TUYẾT RƠI TRÊN BLOGSPOT
2.1 CODE CSS
Bước 1: Đăng nhập Blogger.
Bước 2: Vào chủ đề -> Chỉnh sửa Html, sau đó , bạn copy mã bên dưới rồi chèn trước thẻ </head>
Code
<style type='text/css'>
