CSS information

Standards information

There are no standards that apply here.

Remarks

In vertical layout, text lines are rotated 90° clockwise. Images are not rotated, but tables are. Box layout in vertical orientations is exactly analogous to layout in the horizontal orientation: width, height, top, bottom, right, and left do not rotate with the text.

Only one block progression is active at a time; these values cannot be combined. See IHTMLCurrentStyle2::writingMode for additive block progression values.

This property is based on the block-progression property of the CSS3 Text Layout module.
