Description

The rtc (ruby text container) element groups a collection of rt elements that hold the annotations related to the contents of the rbc container. The example above contains four Japanese characters (the more complex Kanji symbols), each with its own rb element, while the ruby annotations inside the related rt elements are written in hiragana syllables (known as furigana when used for this purpose). In the example shown above, which was taken from the W3C documentation, there are two rtc elements that provide Japanese and English annotations.

The intended rendering of this code is shown in Figure 1. However, only the first image in the example is behaving—and that’s because it’s a suggested rendering in the W3C documentation. The code’s true rendering is shown in the following two images, which are taken from Internet Explorer and Firefox, respectively.
