Trong bài viết này.Nguyễn Diện Blog sẽ hướng dẫn các bạn tạo một widget slider từ Owl Carousel .Tiện ích này sẽ không phù hợp với những người quan tâm đến tốc độ vì nó chứa khác nhiều Css và Javascript
Tiện ích này chỉ hoạt động với thư viện Jquery phiên bản 2 trở nên vậy nên nếu xài những bản cũ thì bạn nên thay nó bằng những bản mới hơn.Ở đây chúng tôi có một bản cho bạn tham khảo
Tiếp theo,thêm đoạn mã bên dưới vào nơi nào mà bạn muốn hiển thị nó
Tiết theo,Blog của bạn phải được trang bị Fontawesome bằng cách thêm đoạn code bên dưới vào thẻ </head>(Nếu có rồi thì thôi)
https://ajax.googleapis.com/ajax/libs/jquery/3.1.1/jquery.min.js
Tiếp theo,Ta thêm đoạn code bên dưới vào thẻ </head>
<script type='text/javascript'> //<![CDATA[ function loadCSS(e, t, n) { "use strict"; var i = window.document.createElement("link"); var o = t || window.document.getElementsByTagName("script")[0]; i.rel = "stylesheet"; i.href = e; i.media = "only x"; o.parentNode.insertBefore(i, o); setTimeout(function () { i.media = n || "all" }) } loadCSS("https://maxcdn.bootstrapcdn.com/font-awesome/4.7.0/css/font-awesome.min.css"); //]]> </script>
Sau đó bạn lưu lại
<style id='owl-carousel' type='text/css'>
