Các bước thực hiện
1. Đăng nhập vào Blogspot ---> Bố cục (Layout)
2. Trong phần bố cục bạn chọn ---> Thêm tiện ích (chọn cái tiện ích nào dài toàn bộ màn hình nhé, nếu ko mưa tuyết ko phủ khắp blog của bạn đâu)
3. Tìm đến tiện ích ----> HTML/Javascript
4. Copy/Paste code dưới vào là xong... 


Đầu tiên là tạo hiệu ứng tuyết rơi
