title: How to change content of a modal window
body: <p>I am to create modals for ~20 charts. These charts must run permanently, as they record insulation values. They should be accessible by clicking on the controller(These are Displayed on the HTML).</p>
  <p>All modals I found were specifically adapted to 1 element. Since I can't create an endless CSS, I don't know what to do.</p>
  <p>My exact question now: How do I create a modal that can display different elements during runtime?</p>
