if a “box” using transparent border color like “10%” then click “Genarate HTML Files”, Axure9 will genarated a SVG file instead CSS stylesheet, and if you change border color to RGB like “#DDDDDD”, it will revert to CSS stylesheet, I think it’s a problem. Because it will genarate tons of SVG files when you’re using transparent border color in different sizes, including hover style, disabled style , etc.
