Proprietary & Nonstandard Elements
The following elements are not actually deprecated. If something is
deprecated it means that has at some point been defined in a standard but
was removed from a later version of the standard. However, none of the
elements below have ever been defined by any standards, but were rather
added on as ‘features’ by browser vendors. Some never caught on
(wbr, nobr), while others are very
well supported to this day across a wide range of browsers
(embed, marquee). Regardless of
their level of support, their use is discouraged, wherever practically
possible, in favor of using elements that are part of a W3C-approved standard.
