Customizing Select Element Highlight Color Q: How can I modify the highlight color that appears on the element when the mouse hovers over it within a dropdown? A: The provided information regarding highlighting elements within is unclear. However, it seems that you intend to alter the background color of elements. Attempts to do so have been unsuccessful, as the system color takes precedence even with CSS styling. Alternatively, highlighting the entire element on mouseover can be achieved using the following CSS: select:hover { background-color: red; }Copy after login However, the behavior of this workaround varies across browsers. For instance, Chrome does not highlight the options in the dropdown, while Firefox does but fails to restore the default color when hovering away. It is crucial to note that styling form controls reliably is inherently challenging. For further details on this limitation, refer to the following discussion.
