Description: The viewport height refers to the vertical measurement of the visible area of a web page on a device, such as a computer, tablet, or mobile phone. This concept is fundamental in responsive web design, as it determines how content is displayed on different screen sizes. The viewport height can be adjusted using CSS and JavaScript, allowing developers to create smoother and more adaptive user experiences. Technically, it is measured in pixels and can vary depending on the screen resolution and device orientation. Understanding viewport height is crucial for optimizing the display of elements such as images, text, and menus, ensuring they are presented correctly without excessive scrolling. Additionally, it influences how features like grid design and user interface element layout are implemented. In summary, viewport height is an essential aspect of modern web design that directly impacts the usability and accessibility of web pages.
