Answer 1

#cssmenu { 
text-align: center; 
} 

#cssmenu ul { 
    display: inline-block; 
} 

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

#cssmenu ul li a { 
display: block; 
/* Other Link styles here */ 
} 

Answer 2

嗯..如果是好的，您使用的Web框架，我将使用MaterializeCSS framework，因为它使事情变得更加简单。

<html> 
<head> 
    <link rel="stylesheet" href="https://cdnjs.cloudflare.com/ajax/libs/materialize/0.97.3/css/materialize.min.css"> 
</head> 
<body> 
    <nav> 
     <ul class = "center"> 
      <li><a href = "#">Home</a></li> 
     </ul> 
    </nav> 
</body> 
</html> 

如果你运行上面的例子，“home”将居中！

Answer 3

基本上，你需要摆脱你的float: left你的li的，而不是给他们display: inline-block。然后，您可以使用父母ul上的text-align: center来居中菜单。

CodePen

#cssmenu > ul { 
    margin: 0 
    text-align: center; 
} 
#cssmenu > ul > li { 
    display: inline-block; 
    padding: 15px; 
}
