This diagram illustrates the fact that the list marker box has no impact on the position of the principal list box.
Two lists are shown, separated by a horizontal line. Each list contains two items with two lines of text each.
For the upper list, the list marker box (which contains a bullet) is outside and to the left of each list item principal box.
For the lower list, the list marker box (which contains a bullet) is the first inline box inside each list item principal box.
Below the second list, an upward-pointing arrow indicates the left edge of all four list item principal boxes. A label reads, "The left sides of the list item boxes are not affected by marker placement."
