我刚刚在页面中创建了一个导航栏和一个小的主部分，但这里的问题是，在导航栏和主部分之间有一个空间，它们之间没有任何边距或填充。

</html>你说你没有任何页边距。但是你有
main > h1 {
font-size: 60px;
margin: 160px;
}
160px的边距就是你看到的nav和main之间的空白。将其改为margin: 0 160px 160px 160px以将其从'top'移除。
如果您想在main的顶部添加"空格"，请在main上使用padding-top:160px
在main中添加了一个红色。

nav{

position: fixed;
top: 0;
width: 100%;
padding: 10px;
