I have some scripts under <script> tag, but nothing seems to be functional. What am I doing wrong? Here is the link of CodePen: https://codepen.io/msrumon/pen/EJyYxP. Thanks in advance.
So, I did some tweaking, and found that removing all the min and slim texts from URLs was what I needed. So this is my final contents inside <head> tag:
<meta name="viewport" content="width=device-width, initial-scale=1, shrink-to-fit=no">
<link rel="stylesheet" href="https://stackpath.bootstrapcdn.com/bootstrap/4.3.1/css/bootstrap.css">
<link rel="stylesheet" href="https://use.fontawesome.com/releases/v5.8.1/css/all.css">
Thanks to all who advised me something. And kudos to @Arfeo for helping me as well.
You should replace bootstrap and jquery cdn with following cdn there is something wrong with your cdn thats why it is giving error
