我有一个大胆的项目，想要一些建议。我想要一个使用 CSS Diamonds 的网站，我附上了一张图片，以便更好地了解我在做什么。以下是我到目前为止遇到的问题：
- 三角形完全对齐，直到添加一个子菜单，然后右三个向右移动（这在某一点起作用）。子菜单所在的 li 也会丢失其菱形
- 子菜单菱形上的文本未居中。
- 我不能有背景图片，然后是钻石，然后是标题。我尝试了不同的 z-index，但没有奏效。（要查看菜单标题，需要移除背景图片，菱形需要 -1 z-indexed）
- 因为我需要使用 spans 为侧边栏创建三角形文本环绕，所以我不能只将侧边栏 div 设置为菱形，所以我仍然需要在其下方添加菱形。
- 将正确的文本正文和侧边栏文本正文都包裹到菱形会很棒，但是我认为这是不可能的，因此我恢复为仅使用侧边栏包裹。
到目前为止，这是我的 HTML：我已经注释掉了子菜单和我的侧边栏菱形尝试。http://jsfiddle.net/s4XXE/
