+ 11 The perspective-origin Property
perspective-origin-001 = perspective-origin - 0px center('center' computes to '50%' in vertical position)
  • The 'perspective-origin' property set 'center' computes to 50% for the vertical position.
perspective-origin-002 = perspective-origin - center 0px('center' computes to '50%' in horizontal position)
  • The 'perspective-origin' property set 'center' computes to 50% for the horizontal position.
perspective-origin-003 = perspective-origin - 50% bottom('bottom' computes to '100%' in vertical position)
  • The 'perspective-origin' property set 'bottom' computes to 100% for the vertical position.
perspective-origin-004 = perspective-origin - 50% top('top' computes to '0%' in vertical position)
  • The 'perspective-origin' property set 'top' computes to 0% for the vertical position.
perspective-origin-005 = perspective-origin - left 50%('left' computes to '0%' in horizontal position)
  • The 'perspective-origin' property set 'left' computes to 0% for the horizontal position.
perspective-origin-006 = perspective-origin - right 50%('right' computes to '100%' in horizontal position)
  • The 'perspective-origin' property set 'right' computes to 100% for the horizontal position.
perspective-origin-x = perspective property
  • Asserts that origin 'x1' visually moves the objects '-x1*d/(d-1)'
perspective-origin-xy = perspective property
  • Asserts that origin '<x,y>' visually moves the objects '<-x,-y>*d/(d-1)'
regions-transforms-019 = Ahem CSS Regions: 3D transform on named flow (text) content with perspective property set on region
  • Test checks that the 3D transform is applied named content flow, that the perspective set on the region is applied, and that the content is not clipped when the perspective is shifted
transform3d-perspective-009 = 'perspective-origin' and translate()
  • This tests that 'perspective' and 'perspective-origin' have the same effect as an appropriately calculated sequence of translate() and perspective(). The reference file's body has a width of 400px and a height of 100px, so the perspective-origin should be (200, 50). The transform-origin is 'top', which works out to (50, 0). Thus we translate by (150, 50) to get the right origin.
transform3d-perspective-origin-001 = perspective-origin
  • This tests that 'perspective-origin: 0 0' is the same as 'perspective-origin: top left', different from no 'perspective-origin', and different from no perspective or no transform.
