👉 The Preview Fluid is a CSS property used to create smooth, animated transitions between different states of an element, such as hover or focus effects. It allows developers to define how an element's appearance changes over time, providing a more interactive and visually appealing user experience. By specifying keyframes and timing functions, Preview Fluid enables the gradual transition of properties like opacity, color, or position, resulting in a fluid and dynamic visual effect that can enhance the overall design of a webpage. This property is particularly useful for creating engaging user interfaces and improving usability through subtle animations that draw attention to specific elements without overwhelming the user.
