Is is possible to add a break/space here and make a new CSS box?

Hello :wave:

I assume you are using the :cloud: Discourse Air Theme.

Something like this, you can achieve it.

Common CSS

body.archetype-regular,
body.archetype-banner,
body.archetype-private_message {
  #main-outlet {
    margin-top: 30px;
    margin-bottom: 0px;
    background: transparent !important;
    box-shadow: none;
    padding: 0em 0em 5%;
    width: 100% !important;
  
    #topic-title {
      margin-bottom: 0;
      background: var(--secondary);
      padding: 3em 3em 1em;
      border-radius: 1em 1em 0 0;
    }
  
    .container.posts {
      margin-bottom: 0;
      background: var(--secondary);
      padding: 0 3em var(--below-topic-margin);
    }
  
    .topic-above-footer-buttons-outlet.presence {
      margin: 0;
      padding: var(--below-topic-margin) 0;
      background: var(--secondary);
    }
  
    #topic-footer-buttons {
      max-width: 100%;
      background: var(--secondary);
      border-radius: 0 0 1em 1em;
      margin: 0;
      padding: var(--below-topic-margin) 3em 1em;
    }
  
    .more-topics__container {
      border-radius: 1em;
      background: var(--secondary);
      max-width: 100%;
      padding: 3em;
    }
  }
}
