Prerequisites: A Japanese font.

basic rendering, no rb

same Test passes if the text matches the reference graphic.

これは日本語にほんごです。
reference graphic

Assertion: When simple ruby markup is used without the rb tag, the ruby text appears above the base text at approximately half the font size.

Notes:

The Ruby Annotation spec recommends non-normatively that, in the absence of other style information, simple ruby markup should place the ruby text before (ie. above in this case) the base text. This is also the initial value for the CSS3 Ruby Module draft.

= means you should check that the test and reference graphic look the same, except for font differences.
