Я получил дерзкий проект и хотел бы получить совет. Я хочу иметь сайт, который использует CSS Diamonds, я прикрепил изображение, чтобы дать лучшее представление о том, на что я смотрю. Вот проблемы, с которыми я столкнулся до сих пор:

The triangles are perfectly aligned until a submenu is added, then the right three shift to the right (this was working at one point). Also the li in which the submenu is under loses its diamond The text on the submenu diamonds are not centered. I cannot have the background image, then diamond then title. I have tried different z-indexs and it hasn't worked. (To see the menu titles, the background image needs to be removed, and the diamonds need to be -1 z-indexed) Because I need to use spans to create the triangle text wrapping for the sidebar I cannot just make the sidebar div a diamond, so I still need to add the diamond in below it. It would be great to have both the right text body and the sidebar text body wrap to the diamond, however I think this is not possible, therefore I reverted to just having the sidebar wrap.

Вот мой HTML-код: я прокомментировал подменю и мою попытку добавления ромба на боковой панели.http://jsfiddle.net/s4XXE/
