The {{tlx|deprecated code}} template (easiest used from its {{tltlx|dc}} redirect) can be used to indicate, e.g. in template documentation or Wikipedia articles on things like HTML specifications, code that has been [[Deprecation|deprecated]] and should not normally be used. It can also be used to indicate other deleted or deprecated material. On the technical level it is a CSS-styled {{tag|del}} 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 {{tl|dc2}} variant {{dc2|to do this}}; it is otherwise identical.
{{strong|Note: This template does not apply a monospaced font.}} This is so that it can be used inside an existing code (or non-code) block and inherit its font style. If necessary, wrap the template in one of {{tag|code}} (source code), {{tag|kbd}} (example input), or {{tag|samp}} (example output) as [[Semantic HTML|semantically]] appropriate.
