Prediction: Block or Inline?

Predict, then prove. The boilerplate has three elements and empty predictions in CSS comments. Replace each prediction comment with the property that makes the statement true: 1. Make the .badge keep its padding AND width while flowing beside the text → set display on .badge. 2. Make the span-sized .spacer disappear entirely → set display on .spacer. 3. Keep .para as a block — but prove it by setting display explicitly on .para.
