问一个iframe滚动条的问题
<iframe   marginWidth= "0 "   id= "my_iframe "   name= "my_iframe "   scrolling= "yes "   marginHeight= "0 "   src= "welcome.htm "   frameBorder= "0 "   width= "98% "   height= "97% "> </iframe>

这个iframe允许当引用页超出iframe大小时，出现滚动条，但是这样的话，如果引用页没有超出大小，在iframe右侧垂直方向总是有一个虚的滚动条，很难看，怎么样能去掉？
谢谢！

你在把 height= "97% "去掉看看
