Như các bạn đã thấy những trang web hiện nay hầu như đều có nút bấm gọi điện thoại ngay.

Mục đích là để khách hàng không cầm lưu số mà bấm vào số sẽ gọi điện thoại ngay. Rút ngắn thời gian 

Về bản chất, nút bấm này chỉ là một câu lệnh html đơn giản có dạng : 

<a href="tel:0912111222">Hotline: 0912.111.222</a>

Với câu lệnh HTML này: thì bạn sẽ có chữ Hotline: 0912.111.222 (bấm vào gọi ngay cho số đó trên mobile hay responsive của website)

Nhưng ở bài này mình sẽ hướng dẫn các bạn tạo nút bấm Gọi điện bằng hình ảnh. 

Và luôn xuất hiện trên website. Nút bấm này sẽ nhấp nháy và trượt dọc theo 2 bên website giúp khách hàng có thể click và gọi điện bất cứ lúc nào một cách nhanh chóng.

Cách làm như sau: 

Bạn chèn đoạn code sau vào Css của website: 

<style>
