first of all: I‘m not a coder!
I want to inject a dynamic h1 based on page title on a webpage.
Example: <title>Garden</title>
Now I need this as H1 class - I want to include this H1 after a given div class <div class="teaser"></div>
It is may totally simple and I already read some stuff but i don‘t get it…
Fairly trivial
window.addEventListener('DOMContentLoaded', function() {
const h1 = document.createElement('h1')
h1.innerHTML = document.title;
document.querySelector(".teaser").insertAdjacentElement("afterend", h1)
})<!doctype html>
<html>
<head>
<meta charset="utf-8">
<title>Garden</title>
</head>
<body>
<div class="teaser">Teaser</div>
</body>
</html>
