The HTML <address> tag is used for indicating an address, usually related to authorship of the current document, or a section of the document.
If the tag applies to the body element, then it applies to the document as a whole.
The <address> tag must not be used to represent arbitrary addresses (e.g. postal addresses), unless those addresses are contact information for the section. To display postal addresses, simply use the <p> tag.
The <address> tag cannot contain <article>, <aside>, <nav>, <section>, <header>, <footer>, <hgroup>, <h1>-<h6> or other <address> elements.
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.
The following attributes are standard across all HTML 5 tags.
For a full explanation of these attributes, see HTML 5 global 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.
Here are the standard HTML 5 event handler content attributes.
