How Can I Change the Background Color of Selected Options in an HTML `` Element?

Customizing Background Color of Selected Options in HTML <select> Using CSS

The HTML <select> element provides a list of options that users can select from. By default, when a user selects an option, it appears with a blue background. This default behavior may not always align with the desired design. Hence, it becomes necessary to find a solution to override this default and customize the background color of selected options.

CSS offers limited options for directly styling selected options within a <select> element. For instance, setting a CSS property like selected-background-color is not supported.

However, JavaScript offers a workaround to achieve this customization. Here is an example that changes the background color of selected options to red using JavaScript:

In this example, the JavaScript code iterates through the available options within the <select> element and sets the background color of the selected option to red, while all other options have a white background. The change event listener is triggered whenever the user selects an option, allowing the background color to be dynamically updated.

Using JavaScript, it becomes possible to customize the appearance of selected options in a <select> element, offering more control over the visual design.
