问题:

line after IFRAME is not visible in both IE and FF. refer the below code and let me know whether I am doing anything wrong. 

<html>
<body>
line before iframe <br />
<iframe src="about:blank" />
<br /> line after iframe
</body>
</html>

回答1:

you need to close the iframe tag. otherwise the content that comes after it is considered "things to show" when iframe is not supported.

(by the way, i think if you use XHTML to write the <iframe ... /> then IE will take it as HTML instead. IE doesn't understand XHTML as XHTML. It understands it as HTML.)



回答2:

create the iframe with a separate close tag:

<html>
<body>
line before iframe <br />
<iframe src="about:blank"></iframe>
<br /> line after iframe
</body>
</html>

There are some tags (iframe and textarea come to mind) which don't like it when you use their compact form.

I was integrating Facebook Connect in my webpage via iFrame tag, like this:

<iframe src="..." style="..."></iframe>

It worked in all browsers except IE8.

Now I found out, that YOU HAVE to provide a text as content of the tags. Then it works perfectly!

Example:

<iframe src="..." style="...">Your browser does not support iFrames</iframe>

or what I am using now is the following (display just a space):

Solution:

<iframe src="..." style="...">&#160;</iframe>
