Box shadows take up no space. Box shadows do not affect or influence normal flow of boxes. Therefore, box shadows can 'collide' with other boxes and can overlap other boxes (inline box or line box) or be overlapped by other boxes. This test checks that the background of the following line box overlaps the box-shadow of an inline non-replaced box whose box-shadow expands onto and over the following line box. In this test, the box shadow of div#outer-box-shadow is red and protudes out and below onto the following line box.
