YUI Library

The YUI Library, or Yahoo User Interface Library, is a collection of open-source JavaScript and CSS tools developed to help web developers create interactive, user-friendly websites. It provides pre-built components, like sliders and modals, simplifying tasks like handling events, managing layouts, and enhancing browser compatibility. By using YUI, developers can save time and effort while ensuring their web applications perform well and look consistent across different devices and browsers. Though less popular today, YUI played a significant role in web development, particularly before modern frameworks like React and Angular became widespread.
