👉 JS Fluid is a CSS framework designed for creating fluid, responsive web designs that adapt seamlessly across various screen sizes and devices. It extends the capabilities of traditional CSS by introducing a set of predefined units, such as `fluid` (which represents 100% of the parent element's width), `flex`, and `grid`, to help developers build layouts that scale gracefully. JS Fluid also includes utilities for managing spacing, alignment, and transitions, making it easier to craft responsive designs without writing extensive custom CSS. By leveraging these features, developers can ensure their websites remain visually appealing and functional on desktops, tablets, and mobile phones alike.
