如何集中对齐浮动:左侧ul / li导航菜单与css?

[英]How to centrally align a float: left ul/li navigation menu with css?

So I have the following CSS in place to display a horizontal navigation bar using: 所以我有以下CSS来显示水平导航栏使用:

.navigation ul {
  list-style: none;
  padding: 0;
  margin: 0;
}

.navigation li {
  float: left;
  margin: 0 1.15em;
  /*    margin: 0 auto;*/
}

.navigation {
  /*    width: auto;*/
  /*    margin: 0 auto;*/
  text-align: center;
}

My question is: how do I align the navigation bar centrally above the title? 我的问题是:如何将标题上方的导航栏对齐?

Give your .navigation ul a width and use margin:0 auto; 给你的.navigation ul一个宽度并使用margin:0 auto;

.navigation ul 
{
  list-style: none;
  padding: 0;
  width: 400px;
  margin: 0 auto;
}

Well, to use margin:0 auto on something, it must have a defined width. 好吧,要使用margin:0 auto on margin:0 auto ,它必须有一个定义的宽度。 Probably the best workaround is: 可能最好的解决方法是:

ul li {
  display: inline;
  list-style-type: none;
}
ul {
  text-align:center;
}

There are few settings like float, margin which may affect this code to work properly. 有一些设置,如float,margin,可能会影响此代码正常工作。 It works in IE7 too. 它也适用于IE7。 I got this code from an article over at CSS Wizardry . 我从CSS Wizardry的一篇文章中得到了这段代码。

.navigation ul 
{
    list-style: none;
    padding: 0;
    margin: 0;
    text-align: center;/*make this change*/
 }
.navigation li
 {
    float: none;/*make this change*/
    display:inline;/*make this change*/
    margin: 0 1.15em;
 /* margin: 0 auto; */
 }
 .navigation li a {
    display:inline-block;/*make this change*/
 }
 .navigation 
 {
  /*width: auto;*/
  /*margin: 0 auto;*/
    text-align: center;
 }

You could set the <li> 's to be display: inline , then set text-align: center on the <ul> . 您可以将<li>设置为display: inline ,然后在<ul>上设置text-align: center Doing that, you can remove the float: left from the list items and you don't need to have a fixed width for the navigation bar as you would if you used margin: 0 auto . 这样做,您可以从列表项中删除float: left ,并且您不需要像使用margin: 0 auto使用导航栏的固定宽度。

<html>
  <head>
    <style>
      ul { 
        list-style: none;
        text-align: center;
      }

      li {
        display: inline;
        margin: 0 1.15em;
      }
    </style>
  </head>

  <body>
    <ul>
      <li>Option 1</li>
      <li>Option 2</li>
      <li>Option 3</li>
    </ul>
  </body>
</html>

This one works great with me! 这个适合我! (if I'm correct: IE7+) (如果我是对的:IE7 +)

.nav{list-style:none; text-align:center;}
.nav ul{list-style:none;}
.nav li{display:inline;}
.nav a{text-decoration:none; font-size:20px; line-height:20px; display:inline-block;}

<nav class="nav" role="navigation" aria-label="main navigation">
  <ul>
    <li><a href="#">Home</a></li>
    <li><a href="#">Menu</a></li>
    <li><a href="#">Onze producten</a></li>
    <li><a href="#">Impressie</a></li>
    <li><a href="#">Media</a></li>
    <li><a href="#">Contact</a></li>
  </ul>
</nav>
ul {
 display: inline-block;
 text-align: center;
}
.navigation ul 
{
  list-style-type: none;
  padding: 0px;
  width: 200px;
  margin: 0 auto;
}

If you want to keep using your floated LI in your code, you can use this: 如果您想在代码中继续使用浮动LI ,可以使用:
