问当行内块元素换行符时，父包装不适合新宽度

<!-- parent inline-block -->
<div style='display: inline-block;'>
    <div style='display: inline-block; width:200px;'></div>
    <!--
        If this child line breaks, 
        two 200px wide blocks are stacked vertically.
        That should make the parent width 200px,
        but the parent stays much wider than that

  When the red inline-blocks are forced to line break, how do you make a parent with display:inline-block (the green border) snap to fit? How do you get rid of all the extra horiztonal space in the lower green bordered div?
