Hi Gérard, These two tests are based on the example given in the CSS 2.1 spec at http://www.w3.org/TR/CSS2/visuren.html#clearance. However the example there is a bit limited in that the elements in question only have a margin-top. I believe that if they had a margin-bottom that both margin-top and margin-bottom would collapse and it would be that collapsed value that would be used to calculate the clearance. There's nothing in the description of collapsing margins (http://www.w3.org/TR/CSS2/box.html#collapsing-margins) to suggest that margin-top should be considered in its uncollapsed state in this context. The two tests in the title have margin-top and margin-bottom but only margin-top is considered when computing the clearance - I believe this is mistaken and that the tests are invalid. Can anyone comment? Have I got the wrong end of the stick? Thanks, Robert
