<!DOCTYPE html ><!--This test passes if the pages generated are identical for both vertical - lr and horizontal - tb writing - modes by means of making the size of the content we are printing equal to exactly the same number of pages being generated in each writing mode . This sizing is calculated like so : 1 . It is important to note that irrespective of the writing - mode , the print UI always lays out printed pages vertically . Therefore , it is possible to equate the printed content of two different writing modes if both cases generate the exact same number of pages ( and of course no text on the pages , which is why we use background color since it is independent of writing mode ) . 2 . To avoid an unnecessary vertical scrollbar ( since scrolled content will be clipped anyway in the reftest snapshot ) , the maximum number of 5 X3in pages that we should generate for the reftest snapshot are equal to 3 . 3 . Considering a margin of 0 . 5 in on each side of the 5 X3in page , we get the size of the page content area to be 4 X2in per page and to generate exactly 3 printed pages from this in horizontal - tb writing mode , we need a printable area of 4 X6in ( as used below ) . Similarly , the size for the test case printable area is calculated , only considering a vertical - rl writing mode . It is important to note here that when printing this test outside of the test harness , the background color will not show since we omit printing and previewing of background colors by default via the browser printing path . html class="reftest-paged" >body style ="margin:0;" >div style ="background: teal; width:4in; height:6in;" >div >body >html >
