标签: html css menu menuitem

我想将菜单项置于中心位置。目前,菜单项位于左侧

HTML:

<ul id="menu">
  <li><a href="#home">Home</a></li>
  <li><a href="#news">News</a></li>
  <li><a href="#contact">Contact</a></li>
  <li><a href="#about">About</a></li>
</ul>

的CSS:

ul#menu{
    list-style-type: none;
    margin: 0;
    padding: 0;
    overflow:hidden;
    background-color: #000000;
}
ul#menu li {
    float: left;
}
ul#menu li a {
    display: block;
    color: white;
    text-align: center;
    font-family: verdana;
    font-size: 24px;
    padding: 30px;
    text-decoration: none;
}

ul#menu li a:hover {
    background-color: #222222;
}
ul#menu li a:active {
    background-color: #222222;
}

我现在有这个: menu left side

我想要这个: menu middle

您的项目保持不变是因为每个li(菜单项)都有float: left;

解决方案1:在父(容器)中使用带有以下内容的flexbox:

  display: flex;
  align-items: center;
  justify-content: center;
  flex-wrap: wrap;

您需要flex-wrap: wrap;,因为默认情况下,flexbox会将其设置为nowrap,当您的屏幕尺寸很小时,它不会移动响应。

ul#menu {
  list-style-type: none;
  margin: 0;
  padding: 0;
  overflow: hidden;
  background-color: #000000;
  display: flex;
  align-items: center;
  justify-content: center;
  flex-wrap: wrap;
}

ul#menu li {
  float: left;
}

ul#menu li a {
  display: block;
  color: white;
  text-align: center;
  font-family: verdana;
  font-size: 24px;
  padding: 30px;
  text-decoration: none;
}

ul#menu li a:hover {
  background-color: #222222;
}

ul#menu li a:active {
  background-color: #222222;
}
&#13;
<ul id="menu">
  <li><a href="#home">Home</a></li>
  <li><a href="#news">News</a></li>
  <li><a href="#contact">Contact</a></li>
  <li><a href="#about">About</a></li>
</ul>

解决方案2:在父容器上使用text-align: center;,然后在子容器上使用display: inline-block;,删除float: left

ul#menu {
  list-style-type: none;
  margin: 0;
  padding: 0;
  overflow: hidden;
  background-color: #000000;
  text-align: center;
}

ul#menu li {
  display: inline-block;
}

&#13;
&#13;
ul#menu {
  list-style-type: none;
  margin: 0;
  padding: 0;
  overflow: hidden;
  background-color: #000000;
  text-align: center;
}

ul#menu li {
  display: inline-block;
}

ul#menu li a {
  display: block;
  color: white;
  text-align: center;
  font-family: verdana;
  font-size: 24px;
  padding: 30px;
  text-decoration: none;
}

ul#menu li a:hover {
  background-color: #222222;
}

ul#menu li a:active {
  background-color: #222222;
}
&#13;
<ul id="menu">
  <li><a href="#home">Home</a></li>
  <li><a href="#news">News</a></li>
  <li><a href="#contact">Contact</a></li>
  <li><a href="#about">About</a></li>
</ul>
