How to set the width of an iframe in iOS6?

问题

I have an iframe that must be embedded on some websites and it is not well displayed on iPhones. This is because the width attribute (probably height as well) is ignored by mobile Safari.

Is there any workaround?

Thanks!

回答1:

Although width is ignored, min-width isn't. So something like this has the same effect as width:100%:

iframe {
  width: 1px;
  min-width: 100%;
}

回答2:

The width parameter of the iframe is ignored in mobile Safari so the width must be set in px with CSS.

I fixed the problem by checking the user agent with JavaScript. If it's an iOS device, I set the width of the iframe in px with CSS to be the exact size as the container.
