Justify-Content: Space Between 工作不正常

Question

我运行我的代码存在一些问题。我的 header 中有一个导航栏，我想在两者之间添加一些 space。我希望我的链接位于 header 的一侧，而我的公司名称位于另一侧。但是，当我执行 space-between 时，它会将我的链接放在页面的中心。我以前在我的 header 中也有一个材料图标，但我将显示设置为 none（直到它满足我的媒体查询的条件），我认为这可以解决问题，但事实并非如此。对解决这个问题有什么建议吗？

在 nav 上指定 margin-left: auto;。

/* Site-wide */

* {
  margin: 0;
  padding: 0;
  box-sizing: border-box;
}

body {
  display: flex;
  flex-direction: column;
  /* height: 100%; */
}


/* Header */

header {
  display: flex;
  flex-direction: row;
  justify-content: space-between;
  background-color: lightgray;
  align-items: center;
  padding: 0px 0px 5px 5px;
  position: fixed;
  top: 0;
  left: 0;
  right: 0;
}

.logo {
  font-size: 2vh;
}

header a {
  text-decoration: none;
  color: white;
  padding-right: 10px;
}

.material-icons {
  display: none;
}


/* Main */

main {
  display: flex;
  padding-left: 5px;
  margin-top: 50px;
  flex-wrap: wrap;
  /* justify-content: space-around; */
}

.card {
  border: 1px solid black;
  height: 350px;
  width: 300px;
  /* margin: 5rem; */
  margin: 0 20px 2rem 5px;
  background-color: rgba(211, 211, 211, 0.251);
}

.card h3 {
  background-color: rgba(185, 44, 185, 0.803);
  padding-left: 3px;
}

.card p {
