function includeHTML() {
var z, i, elmnt, file, xhttp;
/* Loop through a collection of all HTML elements: */
z = document.getElementsByTagName("*");
for (i = 0; i < z.length; i++) {
elmnt = z[i];
/*search for elements with
a certain atrribute:*/
file = elmnt.getAttribute("w3-include-html");
if (file) {
/* Make an HTTP request using the attribute value as the file name: */
xhttp = new XMLHttpRequest();
xhttp.onreadystatechange = function() {
if (this.readyState == 4) {
if (this.status == 200) {elmnt.innerHTML = this.responseText;}
if (this.status == 404) {elmnt.innerHTML = "Page not found.";}
/* Remove the attribute, and call this function once more: */
elmnt.removeAttribute("w3-include-html");
includeHTML();
}
}
xhttp.open("GET", file, true);
xhttp.send();
/* Exit the function: */
return;
}
}
}
</script> Call includeHTML() at the bottom of the page:

w3.js is pretty cool. https://www.w3schools.com/lib/w3.js and we are focus w3-include-html but consider the below case - 🧾 popup.html
- 🧾 popup.js
- 🧾 include.js
- 📂 partials
- 📂 head
- 🧾 bootstrap-css.html
- 🧾 fontawesome-css.html
- 🧾 all-css.html
- 🧾 hello-world.html
<!-- popup.html -->
<head>
<script defer type="module" src="popup.js"></script>
<meta data-include-html="partials/head/all-css.html">
</head>
<body>
<div data-include-html="partials/hello-world.html"></div>
</body>
<!-- bootstrap-css.html -->
<link href="https://...//dist/css/bootstrap.min.css" rel="stylesheet" />
<!-- fontawesome-css.html -->
<link rel="stylesheet" href="https://.../font-awesome/5.15.4/css/all.min.css" />
<!-- all-css.html -->
<meta data-include-html="bootstrap-css.html">
<meta data-include-html="fontawesome-css.html">
<!--
If you want to use w3.js.include, you should change as below
<meta w3-include-html="partials/head/bootstrap-css.html">
<meta w3-include-html="partials/head/fontawesome-css.html">
Of course, you can add the above in the ``popup.html`` directly.
If you don't want to, then consider using my scripts.

<!-- hello-world.html -->
