Examples

The following two examples show a general approach to using the HTMLMetaElement interface. For specific examples, see the pages for the individual properties as described in the Instance properties section above.

Setting the page description metadata

The following example creates a new <meta> element with a name attribute set to description. The content attribute sets a description of the document and is appended to the document <head>:

const meta = document.createElement("meta");
meta.name = "description";
meta.content =
  "The <meta> element can be used to provide document metadata in terms of name-value pairs, with the name attribute giving the metadata name, and the content attribute giving the value.";
document.head.appendChild(meta);

Setting the viewport metadata

The following example shows how to create a new <meta> element with a name attribute set to viewport. The content attribute sets the viewport size and is appended to the document <head>:

const meta = document.createElement("meta");
meta.name = "viewport";
meta.content = "width=device-width, initial-scale=1";
document.head.appendChild(meta);

For more information on setting the viewport, see <meta name="viewport">.
