First you need to get the element and then you need to set the backgroundImage property to that element like
var goldElement = document.getElementById('gold');
goldElement.addEventListener('mouseover'), (event)=> { `goldElement.style. backgroundImage = "url('path_to_image')" ` }
And change the background to normal when mouse leave.
goldElement.addEventListener('mouseleave', (event)=> { `goldElement.style. backgroundImage = "url('')" ` });

</html>If you want to stay on the color just hovered, then remove the leave function from the above code and from the Tags too.
CodePudding user response：
You can use the :hover property in CSS to add styles only whenever the mouse is over the specific HTML element; and to add an image you can use the CSS property background: url(URL_HERE);
For example, your gold ID can be set to display a background by creating a specific :hover property as such:
#gold:hover {
background: url(" https://via.placeholder.com/600x200.png/FFFF00/");
}

</html>For every image, you would need to provide a separate class - if you don't want this behaviour, consider using JavaScript instead to dynamically adjust the background image.
