Question

我能够显示所有嵌套的li's内联。我不明白的是为什么About和Our Team li元素之间存在差距。我已尝试将margin和padding元素的ul和li设置为0。

<div ng-show = "buttonDisplay" id = "buttonDisplayContent">
          <ul>
            <li><a href = "#"> Home </a></li>
            <li class = "subLi"><a href = "#"> About </a></li>
              <ul class = "nested">
                <li> <a href = "#"> Our Team </a> </li>
                <li> <a href = "#"> Our efforts </a> </li>
              </ul>
            <li class = "nextToNested"><a href = "#"> Blog </a></li>
            <li class = "subLi"><a href = "#"> Services </a></li>
              <ul class = "nested">
                <li> <a href = "#"> Design </a> </li>
                <li> <a href = "#"> Web </a> </li>
                <li> <a href = "#"> Learn </a> </li>
                <li> <a href = "#"> Invent </a> </li>
              </ul>
            <li class = "nextToNested"><a href = "#"> Portfolio </a></li>
            <li><a href = "#"> Contact </a></li>
          </ul>
</div>

CSS

#buttonDisplayContent ul {
  list-style-type: none;
  padding: 0;
}

#buttonDisplayContent ul ul {
  list-style-type: none;
  padding: 0;
}

#buttonDisplayContent ul a {
  text-decoration: none;
  color: #000;
  font-size: 25px;
  font-weight: bold;
}

#buttonDisplayContent ul ul a {
  text-decoration: none;
  color: lightgray;
  font-size: 15px;
  font-weight: bold;
}

.subLi {
  float: left;
  margin: 0;
  padding: 0;
  list-style-type: none;
}

.nested {
  margin-left: 0;
}

.nested li {
  display: inline-block;
  padding-bottom: 6px;
  padding-right: 1%;
  padding-left: 1%;
  padding-top: 8px;
}

#buttonDisplayContent ul li:hover {
  background-color: black;
}

感谢您的帮助。我更改了我的HTML和CSS，如下所示。 Li个元素仍未根据需要对齐。这是一个小提琴：https://jsfiddle.net/qvq87ke1/2/

Answer 1

您的标记看起来不正确。嵌套未排序或有序列表时，它们应与li一起包含，它们将创建一个子列表。

像这样：

<ul>
    <li>One</li>
    <li>Two
        <ul>
            <li>One - Sub Two</li>
            <li>Two - Sub Two</li>
        </ul>
    </li>
    <li>Three</li>
</ul>

您要在ul：

之间添加li

<li class="subLi"><a href="#">About</a></li>
<ul class="nested">
    <li><a href="#">Our Team</a></li>
    <li><a href="#">Our efforts</a></li>
</ul>
<li class="nextToNested"><a href="#">Blog</a></li>

Answer 2

根据更新的问题更新了答案..

尝试在嵌套display:inside;上设置<ul>，并将嵌套的<ul>放在<li>

内

P.S。屏幕截图或小提琴（或至少是你的普通CSS）真的很有用..

Answer 3

您应该使用您的代码发布JSFiddle，这将更容易为您提供帮助。

否则，作为一种良好做法，UL嵌套嵌套应该在之前的LI中（这应该是父级的）。

<li class = "subLi">
  <a href = "#">About </a>
  <ul class = "nested">
    <li> <a href = "#"> Our Team </a> </li>
    <li> <a href = "#"> Our efforts </a> </li>
  </ul>
</li>

也许这就是问题所在。

Answer 4

“a”元素也可能在浏览器中有一些填充/边距。最佳实践是在项目开始时import a reset.css file清除所有应用浏览器的CSS并自行设置样式或使用框架。

Answer 5

我明白了。我不必要地浮动了li个元素。

<div ng-show = "buttonDisplay" id = "buttonDisplayContent" >
  <ul>
    <li><a href = "#"> Home </a></li>
    <li class = "subLi"><a href = "#">About </a>
      <ul class = "nested">
        <li> <a href = "#"> Our Team </a> </li>
        <li> <a href = "#"> Our efforts </a> </li>
      </ul>
    </li>
    <li class = "nextToNested"><a href = "#"> Blog </a></li>
    <li class = "subLi"><a href = "#"> Services </a>
      <ul class = "nested">
        <li> <a href = "#"> Design </a> </li>
        <li> <a href = "#"> Web </a> </li>
        <li> <a href = "#"> Learn </a> </li>
        <li> <a href = "#"> Invent </a> </li>
      </ul>
    </li>
    <li class = "nextToNested"><a href = "#"> Portfolio </a></li>
    <li><a href = "#"> Contact </a></li>
  </ul>
</div>
