This tutorial is about a very useful CSS unit. The CSS viewport unit is giving you the possibility, to make your webpage responsive to the viewport of the device, it is viewed with.
In this tutorial we are talking about two of these viewport units: vw, vh
vw: 1/100 (1%) of the current viewport width
vh: 1/100 (1%) of the current viewport heigth
To get a more practical idea of these units, this tutorial will show you an easy example, using these units.
