When the sandbox attribute exists, and it will:

  • treat the content as being from a singular origin
  • It blocks form submission
  • It blocks script execution

  • It also preventing links from targeting other browsing contexts
  • It stop the content to navigate its top-level browsing context
  • block automatically triggered features (such as automatically playing a video or automatically focusing a form control)

The value of the sandbox attribute will either be simply sandboxed (then all restrictions are applied) or a space-separated list of pre-defined values which will take away the actual restrictions.
