Tạo thanh cuộn bài viết vô hạn giống Facebook, Twitter

Cách sử dụng thanh cuộn bài viết vô hạn giống như Facebook, Twitter sử dụng đặt biệt hữu ích với những nội dung bài viết dài, cái này các mạng xã hội hay làm vì nó giúp duyệt web nhanh hơn,để sử dụng thủ thuật khá hay này cho blogspot chúng ta cần sử dụng Ajax Infinite Scroll jQuery plugin do namkna phát triển


1. Live Demo: Tại đây
Video Demo:
2. Tính năng của thủ thuật này:

1. Tải nhanh hơn
2. Hiển thị nội dung tăng lên nhiều lần so với dạng truyền thống,
3. Trực quan hơn với độc giả xem bằng các thiết bị cảm ứng.
4. Thích hợp nhất cho blog sử dụng nhiều hình ảnh nặng
5. Danh mục chính được đơn giản hóa
6. Cam kết sử dụng cao hơn

3. Cách làm: Có 2 cách để làm thủ thuật này:
Cách 1: cách này nhanh hơn nhưng chỉ áp dụng được trên trang chủ, trang nhãn và trang lưu trữ
