好的，所以我已经在 SO 上搜索了大约 50 个左右的线程，但还找不到解决方案。我有一个 1000px 宽 x 47px 高的导航栏。我有一个 135px 高和 167px 宽的标志。我希望此图像位于菜单的中心位置并在其上方延伸。该图像具有我想连接到菜单边缘两侧的倾斜设计。这是我希望它的外观与现在的外观的样机。

margin: 0;在你的CSS.ribbon img取消margin-top: -100px;上面。所以只需像这样删除margin: 0;：

.ribbon img {
    position: relative;
    margin-top: -100px;
    background-color: whitesmoke;
    float: left;
    padding: 0;
    width: 167px;
    height: 117px;
    vertical-align:bottom;
    display: inline-block;
}

看起来您需要在 logo-nav.png 上设置负边距顶部（我个人会在 img 标签上内联），可能还必须设置 z-index 以使图像高于其他一切（如果还没有的话）。
