Quick Reference
The background-position property sets the starting position of a background image, which by default is the top-left corner of an element. Unless otherwise specified, the image will repeat both vertically and horizontally to fill the element.
div {
background-image: url("my-background.jpg");
background-positon: right center;
background-repeat: no-repeat;
background-color: red;
}
Note
background-position should not be confused with background-origin. background-position sets the starting position of the background image (e.g., left top, right bottom, center center). background-origin sets the positioning as it applies to the padding, border, and content (see background-clip).

Using JavaScript
The HTML element can also be styled using JavaScript and the element’s id.
document.getElementById('my_div').style.backgroundPosition = 'right center';
<button onclick='my_function()'>Click Here</button>
<script>
function my_function() {
document.getElementById('my_div').style.backgroundPosition = 'right center';
}
</script>
CSS Notes:
- The “inherit”, “initial” and “unset” keywords can be used with any CSS property to set its value
- In CSS there are many ways to express a color value in a property
