Make your window an inch or two bigger than than the width of one inline-block. All inline-blocks should be the same size. Try resizing the window so that inline-blocks wrap in one or two columns.

The first line is indented. Therefore, the first block on the first line, if the line is short enough, should end up wrapping onto two lines internally. The other boxes should be the same size as they were without the indent.
