This document does not discuss a number of elements. They fall into two classes:
Deprecated elements. These elements are relics of the earlier days of HTML, and there are better and more modern techniques to replace them.
Unrecommended elements: parts of XHTML that, in the author's opinion, represent bad practices and techniques.
If you need to use any of these features, refer to the XHTML 1.1 standard.
These features are officially part of XHTML, but may disappear in future versions.
This element meant “line break here.”
Instead, use a
div element to put
each line into its own block.
These presentational elements were used to get specific font
presentations: typewriter type, italic, boldface,
and strikeout type. Use structural elements
instead, such as
strong, or use
span elements that are linked to CSS rules
as described in Section 5, “Separating content and presentation with CSS”.
These attributes could be used to change the horizontal or vertical alignment of headings, paragraphs, and other elements. Because it is good practice to separate structure from presentation, alignment should be handled in a stylesheet. See Section 5, “Separating content and presentation with CSS”.
