Documentation is at its best when it's consistent. The MDN style guide describes our writing and layout standards...
Note: This page is not yet written, as we are updating our style rules at present. Please review our older style guide for the time being.
- On MDN, the term obsolete marks an API or technology that is not only no longer recommended, and which is no longer implemented in the browser. For Mozilla-specific technologies, the API is no longer implemented in Mozilla code; for Web standard technology, the API or feature is no longer supported by current, commonly-used browsers.
- On MDN, the term deprecated marks an API or technology that is no longer recommended, but is still implemented and may still work. These technologies will in theory eventually become obsolete and be removed, so you should stop using them. For Mozilla-specific technologies, the API is still supported in Mozilla code; for Web standard technology, the API or feature has been removed or replaced in a recent version of the defining standard.
