Deprecated
This feature has been removed from the Web standards. Though some browsers may still support it, it is in the process of being dropped. Avoid using it and update existing code if possible; see the compatibility table at the bottom of this page to guide your decision. Be aware that this feature may cease to work at any time.

The HTML <content> element is used inside of Shadow DOM as an insertion point. It is not intended to be used in ordinary HTML. It is used with Web Components.

속성

This element includes the global attributes.

select
A comma-separated list of selectors. These have the same syntax as CSS selectors. They select the content to insert in place of the <content> element.

예제

Here is a simple example of using the <content> element. It is an HTML file with everything needed in it.

참고: For this code to work, the browser you display it in must support Web Components. See Enabling Web Components in Firefox.

<html>
  <head></head>
  <body>
  <!-- The original content accessed by <content> -->
  <div>
    <h4>My Content Heading</h4>
    <p>My content text</p>
  </div>

  <script>
  // Get the <div> above.
  var myContent = document.querySelector('div');
  // Create a shadow DOM on the <div>
  var shadowroot = myContent.createShadowRoot();
  // Insert into the shadow DOM a new heading and 
  // part of the original content: the <p> tag.
  shadowroot.innerHTML =
   '<h2>Inserted Heading</h2> <content select="p"></content>';
  </script>

  </body>
</html>

If you display this in a web browser it should look like the following.

[1] If Shadow DOM is not enabled in Firefox, <content> elements will behave like HTMLUnknownElement. Shadow DOM was first implemented in Firefox 33 and is behind a preference, dom.webcomponents.enabled, which is disabled by default.
