Question

我创建了一个导航栏，您可以在https://jsfiddle.net/atgdLafa/

中查看其代码

并有两个问题：

1-为什么<div>容器的 id name 和<ul>必须相同？如果我更改主容器的id名称，则列表的排列会更改。< / p>

2 - 我如何改变列表之间的差距（假设'家'和'音乐'）

       #navcontainer{
      height: 35px;
      width: 1000px;
      background-color: #ffffff;
      padding-right: 0px;
      margin-top: 0px;
      margin-right: auto;
      margin-left: auto;
      margin-bottom: 0px;
      border:1px solid #f2f2f2;

Answer 1

从id移除ul - 您不需要使用CSS。

更改margin-left规则的#navcontainer ul li以更改标签之间的间距：

#navcontainer {
  height: 35px;
  width: 1000px;
  background-color: #ffffff;
  padding-right: 0px;
  margin-top: 0px;
  margin-right: auto;
  margin-left: auto;
  margin-bottom: 0px;
  border: 1px solid #f2f2f2;
}
/*styling navigation bar*/

#navcontainer ul {
  height: 35px;
  background: #ffffff;
  list-style: none;
  float: right;
  width: 990px;
  background-color: #ffffff;
  font-family: Tahoma;
  margin: auto 0;
  padding-right: 0px;
}
#navcontainer ul li {
  display: inline-block;
  border-top-left-radius: 5px;
  border-top-right-radius: 5px;
  overflow: hidden;
  margin-left: 10px; /* Increase space between tabs */
}
#navcontainer ul li a {
  text-decoration: none;
  float: right;
  text-align: center;
  line-height: 35px;
  font: Tahoma;
}
#navcontainer ul li a:hover {
  color: #ffffff;
}
li.home a {
  color: #ffffff;
  background-color: #0a0a5c;
  font-weight: bold;
  font: Tahoma;
  font-size: 12px;
  height: 35px;
  width: 80px;
}
li.musicarchive a {
  color: #ffffff;
  background-color: #0a0a5c;
  font-weight: bold;
  font-size: 12px;
  height: 35px;
  width: 120px;
}
li.health a {
  color: #ffffff;
  background-color: #0a0a5c;
  font-weight: bold;
  font-size: 12px;
  height: 35px;
  width: 90px;
}
li.artandculture a {
  color: #ffffff;
  background-color: #0a0a5c;
  font-weight: bold;
  font-size: 12px;
  height: 35px;
  width: 120px;
}
li.tech a {
  color: #ffffff;
  background-color: #0a0a5c;
  font-weight: bold;
  font-size: 12px;
  height: 35px;
  width: 110px;
}
li.home a:hover {
  background: #bb0700;
}
li.musicarchive a:hover {
  background: #dd423b;
}
li.health a:hover {
  background: #B3DE83;
}
li.artandculture a:hover {
  background: #dd423b;
}
li.tech a:hover {
  background: #646373;
}

<div id="navcontainer">
  <ul dir="rtl">
    <li class="home"><a href="./index.php">home</a>
    </li>
    <li class="musicarchive"><a href="music/index.php">music</a>
    </li>
    <li class="health"><a href="health/health.php">health</a>
    </li>
    <li class="artandculture"><a href="./artandculture/artandculture.php">art</a>
    </li>
    <li class="tech"><a href="./tech/tech.php">tech</a>
    </li>
  </ul>
</div>
