In order to create a mask in QGIS that can focus the map readers' attention, I will be demonstrating the use of The shape digitalization tool, move feature using advanced digitalization, Inverted polygons style, Shapeburst style and finally Color ramps. I will demonstrate a series of solutions ranging from a simple borderline to a complex colourramp controlled shape burst styling
