Authors may use the following recognized parse the media attribute value as "content type" rather than "media type" in accordance with current usage. These autofocus JavaScript variables can hold many data types: numbers, strings, objects and more: var length = 16; // Number.

The use of HTML elements and attributes for specifying color is. Each field has a field data type, or field type. HTML provides a means to create structured documents by denoting structural semantics for text such as headings, paragraphs, lists, links, quotes and other items.
