在框架中允许 css

Allow css in framework

如何在自定义框架中允许 CSS? 我使用此视频 link. But it does not allow the use of CSS, JS or any kind of files besides PHP. I have tried checking if the file contains CSS and then excluding it but that also does not work. Does anyone have any suggestions? Here is the link to the github project.

中的框架

您可以在 PHP 个文件中使用 HTML

<!DOCTYPE html>
<html lang="en">
<head>
  <meta charset="UTF-8">
  <meta http-equiv="X-UA-Compatible" content="IE=edge">
  <meta name="viewport" content="width=device-width, initial-scale=1.0">
  <title>Document</title>
  <link rel="stylesheet" href="style.css">
</head>
<body>
  <?php
require_once('Routes.php');

function __autoload($class_name)  {

      if (file_exists('./classes/'.$class_name.'.php'))
      {
        require_once './classes/'.$class_name.'.php';
      }
      else if (file_exists('./controllers/'.$class_name.'.php'))
      {
        require_once './controllers/'.$class_name.'.php';
      }
      //a  special function in php that autoloads
      //classed from ur classes folder
}
 ?>
</body>
</html>
