I have built a website using html, css and php. I have downloaded and installed drupal 8 to use a CMS system to take the sites design to the next level. I have ordered one book and been searching online and unable to find anything that explains what I want to do. If I have the below simplified example code now, how do I make the page use the Drupal 8 theme I have?
<html> <head> <title>Welcome Page</title> <link rel="stylesheet" type="text/css" href="style.css" /> </head> <body> <div id="wrapper"> <?php include_once "navBar.php"; echo '<div id="content">'; echo "Welcome to the site"; ?> </div> </body> </html>
