Cách Thực Hiện:
Các bạn chỉ cần sao chép đoạn mã ở từng mẫu sau đó dán dưới thẻ <body> là được nhé.
Mẫu 1:
Mô tả nhẹ xíu nhé.
- Hai câu đối trang trí hai bên trang web
- Hình ảnh tết gồm bánh chưng, bánh dày, trẻ em vui chơi, ông đồ....
<style type="text/css">body{padding-bottom:20px}</style><img style="position:fixed;z-index:9999;top:0;left:0;wight:300px; height: 400px;" src="https://imgur.com/KzJh7E6.png""/><img style="position:fixed;z-index:9999;top:0;right:0;wight:300px; height: 400px;" src="https://imgur.com/jDBBwDz.png"/><img style="position:fixed;z-index:9999;bottom:0px;left:0px" src="https://imgur.com/gvgEkIN.png"/>
Mẫu 2:
Mô tả nhẹ nữa nè
- Hai câu đối trang trí hai bên trang web
- Hình ảnh tết gồm bánh chưng, bánh dày, trẻ em vui chơi, ông đồ....
<style type="text/css">body{padding-bottom:20px}</style><a href="#" target="_blank"><img style="position:fixed;z-index:9999;top:0;left:0" src="https://imgur.com/Mvv2KdX.png" _cke_saved_src="https://imgur.com/Mvv2KdX.png"/></a><a href="#" target="_blank"><img style="position:fixed;z-index:9999;top:0;right:0" src="https://imgur.com/uzIAUPS.png"/></a><div style="position:fixed;z-index:9999;bottom:-50px;left:0;width:100%;height:104px;"></div><a href="#" target="_blank"><img style="position:fixed;z-index:9999;bottom:20px;left:20px" src="https://imgur.com/Cqx5E4M.png"/></a>
Cái này thì hiệu ứng nhé
