Any online resource for Chinese grammar written in Bopomofo(注音) and traditional characters(正體字)?

Hi all,

I'm learning Chinese grammar from this website, and while it's so far great, it's bothering me that the website uses Pinyin and simplified characters all the way through, with no option to convert them into Taiwanese equivalents.

I have nothing against the mainland convention, but since I liked Bopomofo a lot and decided to pick up traditional characters for maximum accessibility to East Asian classic literature and history, I want to find a learning resource written in Bopomofo and traditional characters, if there is any.

Does anyone know such a resource for Chinese grammar? So far, all I could find were some pdfs written by Taiwanese people in traditioanl characters for Taiwanese audiences with no English explanations.
