如何将导航栏与 css 居中对齐

Question

我需要帮助将我的导航栏对齐到中心 这是我的代码 它有什么问题？ 它不会将菜单与中心对齐。

 #nav { position: absolute; left: 0px; height: 40px; background-color: #2C64B4; width: 100%; margin: 0 auto; } #nav ul { margin: 0; padding: 0; list-style-type: none; } #nav ul li { margin: 0; padding: 0; float: left; } #nav ul li a { text-decoration: none; padding: 10px 20px; display: block; color: #FFF; text-align: center; }

 <div id="nav"> <ul> <li><a href="#">Home</a> </li> <li><a href="#">About Us</a> </li> <li><a href="#">Blah</a> </li> <li><a href="#">exampl</a> </li> </ul> </div>

Answer 1

一种方法是将#nav ul的display设置为inline-block 。 然后将text-align: center添加到父元素以将子元素ul居中：

示例在这里

#nav {
    position: absolute;
    left: 0px;
    height: 40px;
    background-color: #2C64B4;
    width: 100%;
    text-align: center;
}
#nav ul {
    margin: 0;
    padding: 0;
    display: inline-block;
}

或者，您也可以将父元素的display设置为#nav为flex ，然后添加justify-content: center以水平居中子元素。

示例在这里

#nav {
    position: absolute;
    left: 0px;
    height: 40px;
    background-color: #2C64B4;
    width: 100%;
    display: flex;
    justify-content: center;
}

Answer 2

这里没什么大不了的。

只需将text-align:center添加到ul并使li display:inline-block

HTML

<div id="nav">
    <ul>
        <li><a href="#">Home</a>
        </li>
        <li><a href="#">About Us</a>
        </li>
        <li><a href="#">Blah</a>
        </li>
        <li><a href="#">exampl</a>
        </li>
    </ul>
</div>

CSS

#nav {
    position: absolute;
    left: 0px;
    height: 40px;
    background-color: #2C64B4;
    width: 100%;
    margin: 0 auto;
}
#nav ul {
    margin: 0;
    padding: 0;
    list-style: none;
    text-align: center;
}
#nav ul li {
    margin: 0;
    padding: 0;
    display: inline-block;
}
#nav ul li a {
    text-decoration: none;
    padding: 10px 20px;
    display: block;
    color: #FFF;
    text-align: center;
}

将 ul 的 css 更新为

#nav ul {
    margin: auto;
     padding: 0;
     overflow: hidden;
     width: 60%;
}

使用这个 CSS 你会得到解决方案。 添加 Li 相对位置，如果您需要下拉某些类别

}

Answer 6

你可以设置你的 ul 来显示：inline-block; 并设置文本对齐：居中； 到父导航：

#nav {
    position: absolute;
    left: 0px;
    height: 40px;
    background-color: #2C64B4;
    width: 100%;
    text-align:center;
}   
#nav ul {
    margin: 0;
    padding: 0;
    display: inline-block;
}
