feature: iframe[seamless] status: caution tags: none kind: html polyfillurls: moreurl:

This attribute instructs browsers to treat the iFrame's content more like inline markup than it would otherwise. Specifically, this means:

  • Hyperlinks navigate the parent context
  • The parent's stylesheets cascade in (importantly, the inverse is not true)
  • More "neutral" rendering, roughly equivalent to declaring: scrolling="no" marginwidth="0" marginheight="0" frameborder="0" vspace="0" hspace="0"

Because the user experience of following hyperlinks is so drastically altered in supporting browsers, use this attribute with caution.

Also see more about implementing iframe[seamless] responsibly on Bocoup's blog.
