A viewport is the visible area of a web page typically determined by the size of the deviceโ€™s display or browser window.

Itโ€™s important to understand the foundational responsive behaviour of the layouts required, for all device types and sizes.

The narrowest width of a smartphone tends to be 320px and the widest desktop can be more than 2560px.
