笔划-dashoffset 属性用于设置沿 SVG 路径的位置，笔划的虚线图案将从该位置开始。较高的值意味着破折号将从更远的位置开始。

语法:

stroke-dasharray: <length> | <percentage>

属性值:

length: It is used to set the offset in length units. The values are resolved on the basis of the path length of the element.

示例 1: 设置线中虚线的偏移量。

```html <!DOCTYPE html>
       CSS | stroke-dashoffset           .stroke1 {       stroke-dashoffset: 0;

stroke: green;       stroke-dasharray: 40;       stroke-width: 20px;     }

.stroke2 {       stroke-dashoffset: 15px;

stroke: red;       stroke-dasharray: 40;       stroke-width: 20px;     }

.stroke3 {       stroke-dashoffset: 30px;

stroke: orange;       stroke-dasharray: 40;       stroke-width: 20px;     }
