Vh and vw: how and why to use them in Webflow

Modern web design increasingly relies on relative units such as viewport height (vh) and viewport width (vw) to achieve responsive layouts that adapt to various screen sizes, moving away from traditional pixel-based measurements. These units allow for dynamic scaling of elements and typography, providing a consistent and aesthetically pleasing user experience regardless of the device used to access the website. While percentage-based units are tied to the parent element, vh and vw are based on the viewport, making them ideal for maintaining flexibility and independence from base font sizes. Browser support for these units is robust across major versions, although using vw for full-width settings may require caution due to potential issues with scrollbar width in certain browsers. Webflow and other platforms facilitate the implementation of vh and vw values, offering designers an effective method to ensure their content remains appropriately scaled to fit the viewing area.
