what is jquery.scrollto fr?

jQuery.scrollTo is a jQuery plugin that adds animated scrolling to webpages. Instead of a page jumping instantly to a new position when a user clicks a link or a button triggers a scroll, this plugin makes the page glide smoothly to the destination. It works on the whole browser window as well as on individual scrollable elements within a page, such as a div with its own scrollbar. The plugin accepts many formats for specifying where to scroll: a fixed pixel number, a percentage of the container's size, a relative offset (scroll 50 pixels from the current position), the word "max" to jump to the very bottom, or a CSS selector or DOM element to scroll to. The scroll can move horizontally, vertically, or both, and you can control the speed and the easing curve the animation follows. Several settings let you adjust behavior: you can stop the animation if the user manually scrolls during it, add an offset so the target element lands slightly below the top edge of the screen, or scroll one axis before the other. A callback function runs when the animation finishes, allowing you to trigger other effects afterward. The plugin is designed to behave like jQuery's built-in animation system, and any animation it creates can be stopped using jQuery's standard stop and finish methods. It can be installed from npm, Bower, or a CDN, and requires jQuery 1.8 or higher. Two companion plugins from the same author build on this one: jQuery.localScroll simplifies anchor-link navigation, and jQuery.serialScroll makes scrolling slideshows. The license is MIT.
