    A dialog element is in one of two modes: normal alignment or - centered alignment. When a dialog element is created, it must be placed in - the normal alignment mode. In this mode, normal CSS requirements apply to the - element. The centered alignment mode is only used for dialog elements - that are in the top layer.

    - -

    When an element subject is placed in centered alignment mode, and when - it is in that mode and has new rendering boxes created, the user agent must set up the element - such that its static position of the edge that corresponds to subject's parent's - block-start edge, for the purposes of calculating the used value of the - appropriate box offset property ('top', 'right', 'bottom', - or 'left'), is the value that would place the element's margin edge on - the side that corresponds to subject's parent's block-start side as far - from the same-side edge of the viewport as the element's opposing side margin - edge from that same-side edge of the viewport, if the element's dimension - ('width' or 'height') in subject's parent's block flow - direction is less than the same-axis dimension of the viewport, and otherwise - is the value that would place the element's margin edge on the side that corresponds - to subject's parent's block-start side at the same-side edge of the - viewport.

    - -

    If there is a dialog element with centered alignment and that is - being rendered when its browsing context changes viewport - dimensions (as measured in CSS pixels), or when this - dialog element's parent changes block flow direction, then the user - agent must recreate the element's boxes, recalculating its edge that corresponds to this - dialog element's parent's block-start edge as in the previous - paragraph.

    - -

    This static position of a dialog element's edge with centered - alignment must remain the element's static position of that edge until its boxes are - recreated. (The element's static position is only used in calculating the used value - of the appropriate box offset property ('top', 'right', - 'bottom', or 'left') in certain situations; it's not used, for instance, - to position the element if its 'position' property is set to - 'static'.)

    - -

    User agents in visual interactive media should allow the user to pan the viewport - to access all parts of a dialog element's border box, even if the - element is larger than the viewport and the viewport would otherwise not - have a scroll mechanism (e.g. because the viewport's 'overflow' property - is set to 'hidden').
