Answer 1

尝试将内联CSS用作边框颜色。

style="border: 5px solid #333"

Answer 2

I can't recreate your scenario to be sure, but I've had many style issues occur when I've inadvertently "self closed" an iframe element. It is not a self closing element. It's worth trying...

Instead of :

 <iframe frameborder="0" height="768px" width="95%" id="loader" src="" name="loader"/>

Do this:

 <iframe frameborder="0" height="768px" width="95%" id="loader" src="" name="loader"></iframe>
