您必须使用 seamless 属性:

This Boolean attribute indicates that the browser should render the inline frame in a way that makes it appear to be part of the containing document, for example by applying CSS styles that apply to the <iframe> to the contained document before styles specified in that document, and by opening links in the contained documents in the parent browsing context (unless another setting prevents this). In XHTML, attribute minimization is forbidden, and the seamless attribute must be defined as <iframe seamless="seamless">.

问题是浏览器支持目前可以忽略不计。同时，您可以观看Seamless iframes. The future, today! ，一个幻灯片，可以让您了解如何实现这些功能。
