First of all, we must understand that there isn’t any best option of measurement unit for all cases, and that’s why this question is mostly opinion-based. But let’s discuss each of the units.

You can disable form fields by using some CSS. To disable form fields, use the CSS pointer-events property set to “none”.
<!DOCTYPE html>
<html>
<head>
<title>How to Disable Form Fields with CSS</title>
<style>
input[name=yourName] {
pointer-events: none;
}
</style>
</head>
<body>
<input type="text" name="yourName" value="blog it">
</body>
</html>
The <iframe> tag creates an inline frame for embedding third-party content (media, applets, etc.). Although the content of the frame and the web page are independent, they can interact through JavaScript.
<!DOCTYPE html>
<html>
<head>
<title>HTML <iframe> Tag</title>
</head>
<body>
<iframe src="http://blog-it.tn/"></iframe>
</body>
</html>

A basic HTML page always begins with the declaration of the document type or doctype. It is a way to inform browsers about the type of document. The doctype is always the first element at the top of all HTML files. Then we have sections and subsections, each has its title and subtitle. These titles and section elements help the reader to perceive the meaning of the content.
