HTML 5 <header> Tag

The HTML <header> tag represents a group of introductory or navigational aids.

Headers can contain headings, subheadings, version information, navigational controls, etc.

According to the HTML5 specification:

The <header> element is intended to usually contain the section's heading (an <h1>-<h6> element or an <hgroup> element), but this is not required. The <header> element can also be used to wrap a section's table of contents, a search form, or any relevant logos.

The <header> tag cannot be placed within a <footer>, <address> or another <header> element.

Also see the <hgroup> tag.

The <header> tag was introduced in HTML 5.

Attributes

HTML tags can contain one or more attributes. Attributes are added to a tag to provide the browser with more information about how the tag should appear or behave. Attributes consist of a name and a value separated by an equals (=) sign, with the value surrounded by double quotes. Here's an example, style="color:black;".

There are 3 kinds of attributes that you can add to your HTML tags: Element-specific, global, and event handler content attributes.

The attributes that you can add to this tag are listed below.

Element-Specific Attributes

The following table shows the attributes that are specific to this tag/element.

Global Attributes

The following attributes are standard across all HTML 5 tags (although the tabindex attribute does not apply to dialog elements).

For a full explanation of these attributes, see HTML 5 global attributes.

Event Handler Content Attributes

Event handler content attributes enable you to invoke a script from within your HTML. The script is invoked when a certain "event" occurs. Each event handler content attribute deals with a different event.

For a full list of event handlers, see HTML 5 event handler content attributes.
