Template:Deprecated code/doc

Usage
This template (easiest used from its dc redirect) can be used to indicate, e.g. in template documentation or TechInfoDepot 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 )
