Thanks for the answer. That is not quite what I am looking for. I go in Pinegrow to Create a new page or project, then to Plain HTML and new.html.
It opens a new page with the following content:
<html long="en">
<head>
<meta charset="utf-8">
<meta http-equiv="X-UA-Compatible" content="IE=edge">
<meta name="description" content="">
<meta name="author" content="">
<title>New page</title>
<link href="style.css" rel="stylesheet">
</head>
<body>
<div class="pg-empty-placeholder"></div>
</body>
</html>
However, I would like to have this content adapted into that:
<!DOCTYPE html>
<html lang="de-DE">
<head>
<meta charset="utf-8"/>
<meta name="viewport" content="width=device-width, initial-scale=1.0"/>
<title>page name</title>
</head>
<body>
</body>
</html>
Can I save this as a template?
