<meta content="This test checks the rendering process of selecting the middle part of the border-image to be preserved. Since 'border-image-slice' is '50', then the 8 surrounding areas of the border-image area are selecting the white areas of the border-image. The middle part must be filled with red and green area. In which case, only the horizontal center and the vertical center of the border-image must fill the middle area. Therefore, only the green 100x100 area of the border-image must be painted into the middle area." name="assert">
