Description

Despite having been defined as far back as 2001, ruby doesn’t enjoy great support in browsers. For a change, Internet Explorer is ahead of the game on this one! Created in light of the fact that not all browsers will understand ruby, the rp element may be used to present content to users who are viewing the ruby text on a browser that doesn’t understand or support ruby, but removes that content for browsers that do support ruby. The content inside the rp element should be an opening or closing parenthesis, although there’s no definitive rule about which character should be used. It’s most likely that you’ll use "(",")","[" or "]".

The effect of using rp can be seen in Figure 1.

Only Internet Explorer offers any support for text marked up using ruby at this time. Other browsers ignore the markup and display the ruby text in the order in which it appears in the source.
