In 2023, a variety of CSS button hover effects have emerged to enhance user experience by making buttons more interactive and visually appealing. These effects range from simple color changes to complex animations like spinners, glows, and 3D flips, which signal interactivity and improve usability. Examples include gradient animations, border wipes, and neon effects, each serving different purposes like call-to-action buttons, subscription prompts, or social media links. Platforms like LambdaTest allow developers to test these effects across multiple browsers and devices to ensure consistency and responsiveness. The article emphasizes the importance of designing buttons that are both functional and engaging, encouraging designers to experiment with different effects to enhance the user experience on their sites or apps.
