verge

The "viewport" is the visible area of a page, what gets shown on the user's screen when viewing a website.

The "viewport" property is a dynamic variable, ranging in value based on the user's device, platform, and browser size.

That's why a JavaScript library that can properly detect viewport values is quite important in today's varied Internet market.

verge allows developers to perform various operations involving the viewport. This includes detecting its size, determining if an element is visible or not on the viewport, detect the scrolled viewport area, and many other more.

The verge library works with client-side (browsers, vanilla JS, jQuery or Ender) and server-side (Node.js) environments.
