  <li>The first rule sets a sitewide font and a baseline font size of 10px. These are inherited by everything on the page.</li>
  <li>Rules 2 and 3 set relative font sizes for the headings, different list types (the children of the list elements inherit these), and paragraphs. This means that each paragraph and list will have the same font size and top and bottom spacing, helping to keep the vertical rhythm consistent.</li>
  <li>Rule 4 sets the same {{cssxref("line-height")}} on the paragraphs and list items — so the paragraphs and each individual list item will have the same spacing between lines. This will also help to keep the vertical rhythm consistent.</li>
- <li>Rules 5 and 6 apply to the description list — we set the same <code>line-height</code> on the description list terms and descriptions as we did with the paragraphs and list items.
