Template:Deprecated code/doc

Usage
This template (easiest used from its dc redirect) can be used to indicate, e.g. in template documentation or articles
 * on things like HTML specifications, code that has been deprecated and should not normally be used.

On the technical level it is a CSS-styled  that greys out the text (the near-universal sign in computing
 * and computing documentation for "doesn't work", "don't do this", "bad code", "ignore", "option not available", etc.),
 * and removes that element's usual strikethrough (CSS: "line-through") rendering, which makes the content hard to read.

If you really want that line-through, use the dc2 variant ; it is otherwise identical.

Parameters

 * 1  the content to be marked as deprecated
 * 2 or title a mouse-over "tooltip" (in some browsers, anyway), e.g. for briefly explaining the deprecation,
 * e.g. "Deprecated since HTML 3.0" or "Breaks infobox formatting"


 * y  make the text red instead of grey, for indicating dangerous/error/forbidden things
 * class  assign a CSS class
 * id  assign an HTML ID for #linking and other purposes (must be unique on the page and start with an alphabetic letter)
 * style  add additional CSS styling (can be used to add
 * back in if you want that formatting; a shortcut for this is )
