<meta content="Although margins, borders and padding of inline non-replaced elements do not enter into the line box calculation, they are still rendered around inline boxes. This means that if the height specified by 'line-height' (40px in this testcase) is equal to the content height (40px in this testcase) of contained boxes, then background-color of padding-top area and border-top may 'bleed' into the adjoining preceding line box. Since line boxes are rendered in document order, this causes border-top of 2nd line box (the span element in this testcase) to be painted over border-bottom and padding-bottom of inline boxes of previous line and, in this testcase, over the 1st line box." name="assert" />
