 * 1) Inspect Element
 * 2) Hover over elements until the relevant bit is highlighted (Chrome does that).
 * 3) Select the class "header-container".
 * 4) Expand and hover over inner elements to try and narrow down where the line is.
 * 5) Determine it's in the header-container itself.
 * 6) Look at the CSS and see there is a border-bottom.
