解释
我正在尝试放置我的 SVG Bootstrap 导航栏中的 Logo ，但由于某种原因，它不起作用。我试过使用 <object> (如 CSS Tricks 所推荐)，内联 svg 和 <img> ，如您在下面的代码中所见，但没有任何效果。

您可以保存 SVG与 <object> 一起使用的 Logo 来自 Bootstrap's site或 download here .

最佳答案
您的主要问题是您没有指定 SVG 的大小。如果 SVG 没有 width 或 height 属性，它们默认为“100%”——即 100% 宽度(父容器的)。
下面我刚刚在 CSS 中设置了宽度，现在它是一个更合理的尺寸。您需要添加更多样式以使其位于标题栏中您想要的位置。
#navigation {

.logo {
margin: 0;
}
svg {
width: 50px;
height: 50px;
