This article addresses the common technical challenge of disabling CSS :hover pseudo-class effects through JavaScript. Traditional methods, such as using event.preventDefault() or return false, fail to directly prevent the triggering of CSS :hover states. The paper proposes an elegant solution based on CSS class control: by adding specific class names to HTML elements to limit the application scope of :hover styles and removing these classes when JavaScript is available, dynamic disabling of :hover effects is achieved. This approach avoids the tedious task of overriding individual CSS properties, offers cross-browser compatibility, and adheres to the principles of progressive enhancement.
