<head>
<title>Document</title>
</head>
- The
head element represents a collection of metadata for the document
-
One or more elements of metadata content, of which exactly one is a
title
element is required in almost all cases.
-
HTML5-compliant browsers automatically create a
head element if its tags are omitted in the
markup
-
If the document is an
iframe srcdoc document or if title
information is available from a
higher-level protocol (such as email), head may contain zero or more elements of metadata
content (W3C)
-
The
title element is a required child in most situations,
but when a higher-level protocol provides title information,
e.g. in the Subject line of an e-mail when HTML is used as an e-mail authoring format,
the title element can be omitted.
