I have a stack in a section that I want to be centre aligned vertically and horizontally on all view ports. When I do that using the alignment buttons in the inspector, it docks to top of the section for centre alignment (For e.g. vh 25% from top). When I resize the viewport, it still stays as vh 25% as oppose to realigning itself to stay in the centre which in the new size could be at vh 30%. Is there a way to ensure a certain element just stays in the centre in the section regardless of the view port size or width?
