ルビの揃え方を指定する
ruby-align プロパティは、様々なルビボックスの内容がそれぞれのボックスを正確に満たさない場合(ボックスサイズに対して余白ができる場合)に、テキストがどのように配置されるかを指定します。
ruby-align プロパティに指定可能な値は下記の通りです。
start | 
下記の例の様に、ルビの内容は、ベーステキストの開始辺に揃えられます。![]()  | 
|---|---|
center | 
下記の例の様に、ルビの内容は、ベーステキストの中央に揃えられます。![]()  | 
space-between | 
下記の例の様に、ルビの内容は、ベーステキストに対して両端揃えとなります。もし、両端揃えのためのスペースがない場合は中央揃えとなります。![]()  | 
space-around | 
下記の例の様に、ルビの内容は、ベーステキストのボックスサイズに均等に配置されるよう、スペースが配分されます。![]()  |
