How to hide the sidebar from published pages

We will, at some point, add an easy option to hide the sidebar from a published page. For now you will need to use this bit of CSS (in the "Customization" tab in "Design"):

.rendered-page {
  .MuiDrawer-root {
    display:none
  }
  .page-container {
    margin-left: 0;
  }
  .navigation-header {
    display: none;
  }
  .page-title {
    max-width: 100%;
  }
}
