After writing my html and css code, I noticed that the files are not linking properly. Despite checking for errors, I couldn't find any issues within the codes. Here is a snippet of my html file:
<!DOCTYPE html>
<html lang="en" dir="ltr">
<head>
<meta charset="utf-8">
<title>basicapp</title>
<link rel="stylesheet" href="https://stackpath.bootstrapcdn.com/bootstrap/4.5.0/css/bootstrap.min.css" integrity="sha384-9aIt2nRpC12Uk9gS9baDl411NQApFmC26EwAOH8WgZl5MYYxFfc+NcPb1dKGj7Sk" crossorigin="anonymous">
<link rel="stylesheet" type="text/css" href="static/css/basicapp.css"/>
</head>
<body>
<ul>
</ul>
</body>
</html>
The current file structure looks like this:
/desktop/templates/index.html
/desktop/static/css/basicapp.css
