Viewport

A viewport is the visible area of a webpage or application on your device screen. Think of it as the window through which you see the content; anything outside this window isn't visible until you scroll. The size of the viewport depends on your device's screen size and window dimensions. Web designers often tailor content to fit various viewports to ensure a good user experience across devices. Essentially, the viewport determines what part of the digital content you see at any moment without scrolling.
