Standard HTML

Safari and the Web Kit implement a large subset of the HTML 4.01 Specification defined by the World Wide Web Consortium (W3C). This reference defines every symbol in the specification that Safari implements. If a tag is not listed here or in “ HTML Extensions ” , it is not supported by Safari and the Web Kit. Some tags are also marked as deprecated, which means they are supported by Safari, but since they are no longer supported by the HTML specification are not guaranteed to be supported in the future.
