<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.
