In the CSS sample, what is the width of the navigation area?

Explanation:
In a layout with a side navigation, the width of the navigation area is determined by the width property applied to the navigation element. The sample fixes the navigation pane at 165px, so it remains that exact width regardless of how wide the page gets. This common approach keeps a stable sidebar while the main content expands to fill the rest of the space. Often you’ll see the content area offset by a matching margin, such as margin-left: 165px, to ensure the two areas don’t overlap. Note that if the box-sizing model is content-box (the default), the width refers to the content area and padding or borders add to the total width; if box-sizing is border-box, the 165px includes padding and borders, so the overall footprint stays 165px.
