title: Cutting out half a circle header with an SVG
body: <p>Hey there i am trying to achieve the following fix header shape.</p>
  
  <p>It should be responsive and keep the shape, i figured to use a background SVG but i am struggling to cut out the inner circle part instead of having it black as well as scaling it responsively.</p>
