Ở đây chia có 2 loại:
1. Menu cố định ở cuối màn hình mobile
2. Menu ẩn hiện khi cuộn trang.
Khi cuộn xuống menu tạm thời ẩn đi để cho đỡ mất diện tích màn hình, khi cuộn lên menu lại xuất hiện.
Sau đây là hướng dẫn chèn code HTML và CSS vào blogspot để có thanh menu nằm ngang dưới chân trang mobile gồm các nút gọi điện, nhắn tin SMS, nhắn tin Zalo và chat Facebook Messenger.
Bạn hoàn toàn có thể thay đổi icon svg và text khi có nhu cầu sử dụng vào mục đích khác.
Demo menu cố định.

Các đường link thì bạn tìm hiểu tự lấy và thay vào.
Nút Messenger có thể là Fanpage hoặc facebook cá nhân
Ví dụ link facebook cá nhân có dạng: https://www.facebook.com/profile.php?id=xxxxxxxxxxxx
"xxxxxxxxxxxxx" là ID fb cá nhân của bạn.
Hoặc chat facebook có dạng: https://m.me/xxxxxxx
Link zalo: https://m.me/yyyy (yyyy là số điện thoại của bạn)
Nhắn tin: sms:xxxx
Gọi điện: tel:xxxx
Cái này bạn tự tìm hiểu và điền vào hộ mình.
Một số menu chính của blogspot có sử dụng javascript và jquery hỗ trợ có thể bị lỗi không xổ được khi cài đặt menu này cũng như vài tiện ích có thể bị ảnh hưởng nên bạn cần cân nhắc trước khi dùng.
