Add raw HTML to any post/page. In the post/page which needs HTML add a custom field with name: “body”, paste the HTML into the value box, then insert the shortcode [body][/body] where it should appear in the page. To add to the HTML head tag, add a custom field with name: “head” and paste the HTML into the value box. To add multiple [body] tags the syntax [body id=”element1″][/body] can be used, where “element1” is the name of a custom field.
