How can I add multiple layers of SVG polygons in the same SVG? For example, I have a drawing of a car (see snippet) over here, what if I want to add a window on it? If I write the new window markup below the car markup (see snippet) it is not visible. If I write it above the car markup is overwritten.
<svg heght="100" width="100">
<!--bil-->
<polygon points="0,100 0,70 5,65 20,65 30,40 70,40 80,65 95,65 100,70 100,100 90,100 80,90 70,100 30,100 20,90 10,100" style="fill:#777; stroke:#444; stroke-width:3px;">
<!--window-->
<polygon points="30,30 50,30 50,50 30,50" style="fill:blue; stroke:#444; stroke-width:3px;">
</svg>
