<html>
<head>
<title>How to a refer to the size of the border image area</title><!-- Title of the HTML document -->
<style>
/* CSS styling */
#img1 {
  border: 15px solid transparent; /* Sets a transparent solid border with 15px width for the element with id "img1" */
  padding: 15px; /* Adds 15px padding to the element with id "img1" */

  border-image-repeat: round; /* Sets the border image to be repeated and rounded */
  border-image-slice: 30; /* Sets the size of the border image slices to 30 */
  border-image-width: 10%; /* Refers to the size of the border image area as 10% of the element's width or height */
}

</head>
<body>
<p id="img1">border-image-width: 10%;</p><!-- Displays the text "border-image-width: 10%;" -->
</body>
</html>

Explanation:

This HTML document demonstrates how to refer to the size of the border image area using the border-image-width property.
The element with id "img1" is styled to have a transparent solid border with 15px width and 15px padding.
It also uses a border image sourced from "https://www.w3resource.com/w3r_images/border.png", with the border image slices set to 30 and the border image repeated and rounded.
border-image-width: 10%; specifies that the size of the border image area is 10% of the width or height of the element.
