HTML5 - New Attribute Syntax


HTML5 allows four different syntaxes for attributes.


This example demonstrates the different syntaxes used in an <input> tag:



Type

Example


Empty

<input type="text" value="John" disabled>


Unquoted

<input type="text" value=John>


Double-quoted

<input type="text" value="John Doe">


Single-quoted

<input type="text" value='John Doe'>



In HTML5, all four syntaxes may be used, depending on what is needed for the attribute.
