DHTML test

Such test is a simple text variation of the "ABCD" example from figure 6 in

Expected results

There should be one and only one vertical straight, unbroken line under the baseline of the whole word "sample" in all 5 writing-modes.


The position of text decoration lines applying to a parent box must be determined in relation to the same baseline and is not affected by 'vertical-align' applied on its descendants.
