Solution:

HTML Code:

<!DOCTYPE html><!-- Declaration of HTML5 document type -->
<html>
<head>
<title>How to set the a background-image as horizontal and vertical position in percentage of a document</title><!-- Title of the HTML document -->
<style type="text/css">/* CSS style start*/
#xyz1 {
border: 8px solid blue; /* Setting border properties for the element with id "xyz1" */
padding: 40px; /* Setting padding properties for the element with id "xyz1" */
background: url(https://www.w3resource.com/images/w3resource-logo.png); /* Setting background image for the element with id "xyz1" */
background-repeat: no-repeat; /* Preventing the background image from repeating */
background-position: 50% 50%; /* Setting the background image position to 50% from the left and 50% from the top */
}
</style>
<body>
<p>No background-origin (padding-box is default):</p><!-- Paragraph explaining the absence of background-origin -->
<div id="xyz1"><!-- Division element with id "xyz1" -->
<h2>Background image position</h2><!-- Heading inside the division element -->
<p>The background-origin CSS property determines the background positioning area, that is the position of the origin of an image specified using the background-image CSS property.</p><!-- Paragraph explaining background-origin CSS property -->
</div>
</body>
</html>

Explanation:

This HTML document demonstrates how to set a background image to a specific position using percentage values.
The CSS style block defines styling for an element with the id "xyz1".
The background image used in this example is the w3resource logo.
The background image is set not to repeat using background-repeat: no-repeat.
The background position is set to 50% from the left and 50% from the top using background-position: 50% 50%.
This effectively centers the background image both horizontally and vertically within the element.
The HTML content within the div with id "xyz1" explains the concept of background-origin CSS property.
