Answer 1

一种方法是将display的{{1}}设置为#nav ul。然后将inline-block添加到父元素，以便将孩子text-align: center：

居中

Example Here

ul

或者，您也可以将父元素的#nav { position: absolute; left: 0px; height: 40px; background-color: #2C64B4; width: 100%; text-align: center; } #nav ul { margin: 0; padding: 0; display: inline-block; }，display设置为#nav，然后添加flex以使子元素水平居中。

Example Here

justify-content: center

Answer 2

这里没什么大不了的。

只需将text-align:center添加到ul并制作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;
}

更新您的ul css 如

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

您可以将ul设置为：inline-block;并设置text-align：center;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;
}

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

我是这样做的，它确实有效，但您也应该上课并安排移动设备和桌面设备。我也用于引导程序。
