问题
I'm trying to get Iframes to work. I'm running safari, so it is compatible, but when I test it, it comes up blank. Code:
<iframe src="http://www.google.com" width="100%" height="300">
<p>Your browser does not support iframes.</p>
</iframe>
I took the code directly from the w3schools website after using the "try it out" editor so I know it's supposed to work. When I changed the page from a page in their subdirectory to an external page, it shows up blank.
回答1:
The syntax is correct. It's not your fault - Google is blocking iframing using the X-Frame-Options header that newer browsers listen to.
Possible workarounds are explained in this Google forum post.

Follow the instruction in the following Google Developer Site under "IFrame embeds using the IFrame Player API" bullet: https://developers.google.com/youtube/player_parameters
This uses API's JavaScript code to view youtube videos.
Here's the link with a more general instruction https://developers.google.com/youtube/iframe_api_reference#Loading_a_Video_Player
