# iframes

- An [[iframe]] is an easy way to implement [[transclusion]].
- Web content embedded this way must allow it using either [[x-frame]] or [[content security policy]].
  - [[go]] https://support.mozilla.org/en-US/kb/xframe-neterror-page?as=u&utm_source=inproduct
  - please allow [[iframes]] whenever this doesn't carry a [[security risk]]
    - [[embed]] and [[compose]] for the [[greater good]].
    - follow the example of [[wikipedia]].
  - sites that allow iframes are by default [[stoas]].
