It affects the width and height properties.contentbox: The width and height properties specify the size of the element including the padding. borderbox: The width and height properties specify the size of the element including the padding and border. paddingbox: The width and height properties specify the size of the element. The padding, border and margin are added outside of this size. mozimageregionFor elements that have an image, this property sets the area of the image that is used. You can set multiple elements to use the same image but use a different region of the image, reducing the amount of memory required. You can change this property to simulate animation.

This should be set to a numeric value indicating the amount of rounding to use. You must use a unit (usually px for pixels). A higher number makes the outline rounder.mozoutlineradiusbottomleftSets the rounding of the lower left corner of the outline.mozoutlineradiusbottomrightSets the rounding of the lower right corner of the outline.mozoutlineradiustopleftSets the rounding of the upper left corner of the outline.mozoutlineradiustoprightSets the rounding of the upper right corner of the outline.mozoutlinestyleSets the style of the border, which can have the same values as the borderstyle property.mozoutlinewidthSets the width of the outline.mozuserfocusUsed to indicate whether the element can have the focus.
