我的网站顶级菜单遇到了一些麻烦：当我设置一个保证金顶部时，我div中的一个正在移动身体的位置。
背景： 今天我决定对它实施基金会，并注意到他们将身体位置设置为相对的，没有什么大不了解一个小的可理解的问题。 我的顶级菜单由导航栏下方的2个主要div，导航栏和徽标组成。我的导航栏位置是绝对的，而徽标设置为相对位置，因此我网站的元素可以相对于我的徽标位置定位。
当我设置30px的上边距到我的header-logo时会发生什么，并且你可以看到导航栏也从30px移动，因为事实上当我身体被移动了30px实际上只将它设置为header-logo（我知道它因为页面可以向下滚动到这个精确的30px以弥补缺失体积的30px）

<div id="header-logo">
<a href="/"><img src="/style/img/apatikgg_logo.png" width="331" height="96" alt=""/></a>
</div>
如果我没有为此header-logo设置保证金，则身体不会移动。
此时我更痴迷于理解这里发生了什么，而不是解决它，它没有意义，也许它会对你有用吗？
我的代码肯定有问题，特别是边界问题解决了我无法解释的问题。
我还会问一个相关的问题：为什么基金会将身体的位置设定为亲戚？我在网络开发方面相当新，到目前为止总是使用默认的静态位置，所以我想知道它的优点是什么？
无论如何，感谢阅读本文，任何帮助都会非常感激，我希望我已经足够准确，即使这很难描述，我的网站也在本地
谢谢！
