Syntax

fill-rule: nonzero | evenodd | inherit

Property values

nonzero

Default. This rule determines where within the canvas a point falls, or the point's insideness, in relation to the canvas. The location of the point by drawing a ray from that point to infinity in any direction and then examining the places where a segment of the shape crosses the ray. Starting with a count of zero, add one each time a path segment crosses the ray from left to right and subtract one each time a path segment crosses the ray from right to left. After counting the crossings, if the result is zero then the point is outside the path. Otherwise, it is inside.

evenodd

This rule determines the "insideness" of a point on the canvas by drawing a ray from that point to infinity in any direction and counting the number of path segments from the given shape that the ray crosses. If this number is odd, the point is inside; if even, the point is outside.

inherit

Indicates that the property takes the same computed value as the property for the element's parent.
