<html><body><div id=div0 style='border:1 solid red'><div id=div1 style='border:1 solid red;margin:10'>---div1</div><div id=div2 style='border:1 solid red;margin:10'>---div2</div><div id=div3 style='border:1 solid red;margin:10'>---div3</div><div id=div4 style='border:1 solid red;margin:10'>---div4</div>...<div id=divn style='border:1 solid red;margin:10'>---divn</div></div></body></html>

有一个div0里面有div1~divn个div，想在div1~divn前面画一条虚竖线，将div1~divn的中间那条线连起来。
这个怎么实现，求解。

回复讨论(解决方案)

<html><body><div id=div0 style='border-left:1px dashed red;margin-left:8px'><div id=div1 style='border:0px  solid red;'>---div1</div><div id=div2 style='border:0px solid red;'>---div2</div><div id=div3 style='border:0px  solid red;'>---div3</div><div id=div4 style='border:0px solid red;'>---div4</div>...<div id=divn style='border:0px  solid red;'>---divn</div></div></body></html>

设置div0的左边框，去掉子div的左边框

忘了说一句，楼上的还挺快的。
我就是像楼上所说的那么干的，但是利用左边框有一个缺点就是“冒头”，不希望左边的竖线超出div1的中线也不能超过divn的中线。

只希望左侧竖线在div1~divn的中线之间出现。

借楼上代码一用。

4楼代码可用。谢谢
