正在尝试居中导航栏

Question

我在尝试将导航栏居中放置在网页上时遇到问题。我尝试创建一个包装器div来居中，但似乎不起作用。在这个div中唯一有效的就是更改左边距。这是HTML:

body {
  background: #bf5c71 url('body-bg.jpg');
}
.clearfix:after {
  display: inline-block;
  clear: both;
  align-content: center;
}
/*----- Menu Outline -----*/
.menu-wrap {
  box-shadow: inset 0px 0 0 rgba(255, 255, 255, 0.00);
  -webkit-box-shadow: inset 0px 0 0 rgba(255, 255, 255, 0.00);
  display: inline-block;
  margin: 0px auto;
}
.menu {
  display: inline-block;
  margin: auto;
}
.menu li {
  margin-top: 0px;
  margin-right: 0px;
  margin-left: 0px;
  margin-bottom: 0px;
  list-style: none;
  font-family: 'Century Gothic';
}
.menu a {
  transition: all linear 0.15s;
  color: #FF283B;
}
.menu li:hover > a,
.menu .current-item > a {
  color: #F5F5F5;
}
.menu .arrow {
  font-size: 11px;
  line-height: 0%;
}
/*----- Top Level -----*/
.menu > ul > li {
  float: left;
  display: inline-block;
  position: relative;
  font-size: 18px;
}
.menu > ul > li > a {
  padding-top: 2px;
  padding-right: 2px;
  padding-left: 2px;
  padding-bottom: 2px;
  display: inline-block;
  text-shadow: 0px 0px 0px rgba(0, 0, 0, 0.00);
}
.menu > ul > li:hover > a,
.menu > ul > .current-item > a {
  background: F5F5F5;
}
/*----- Bottom Level -----*/
.menu li:hover .sub-menu {
  z-index: 1;
  opacity: 1;
}
.sub-menu {
  width: 100%;
  padding: 3px 0px;
  position: absolute;
  top: 100%;
  left: 0px;
  z-index: -1;
  opacity: 0;
  transition: opacity linear 0.15s;
  box-shadow: 0px 0px 0px rgba(0, 0, 0, 0.0);
  background: 0;
}
.sub-menu li {
  display: inline-block;
  font-size: 16px;
}
.sub-menu li a {
  padding-top: 10px;
  padding-right: 20px;
  padding-left: 20px;
  padding-bottom: 5px;
  display: inline-block;
}
.sub-menu li a:hover,
.sub-menu .current-item a {
  background: #FF283B;
}
img {
  border: thin solid #FF283B;
  margin-left: 5%;
}
h3 {
  margin-top: 3%;
  font-size: 24px;
}
.wrapper {
  display: inline-block;
  margin: 0px auto;
}

<div class="wrapper">
  <div class="menu-wrap">
    <nav class="menu">
      <ul class="clearfix">
        <li>
          <div align="center"><a href="index.html">Home</a></a>
          </div>
        </li>
        <li>
          <div align="center"><a href="#">Projects <span class="arrow">&#9660;</span></a>
            <ul class="sub-menu">
              <li><a href="iap.html">Image Adaptation</a>
              </li>
              <li><a href="sonic.html">Sonic Memory</a>
              </li>
              <li><a href="documentary.html">Documentary Video</a>
              </li>
            </ul>
          </div>
        </li>
        <li>
          <div align="center"><a href="resume.html">Resume</a>
          </div>
        </li>
        <li>
          <div align="center"><a href="about.html">About</a>
          </div>
        </li>
        <li>
          <div align="center"><a href="contact.html">Contact</a>
          </div>
        </li>
      </ul>
    </nav>
  </div>
</div>

我唯一能做的就是使用左边距向左移动条形图。

Answer 1

这就足够了：

  .content {
    text-align: center;
  }

Answer 2

您需要给菜单一个宽度，并将显示更改为"block"

以下是您需要更改的样式

.menu-wrap {
    box-shadow: 0 0 0 rgba(255, 255, 255, 0) inset;
    display: block;
    margin: auto;
    width: 880px;
}

Answer 3

给导航条100%的宽度是个好主意。菜单上的文本居中对齐就可以了。

 .menu-wrap {
        box-shadow: inset 0px 0 0 rgba(255,255,255,0.00);
        -webkit-box-shadow: inset 0px 0 0 rgba(255,255,255,0.00);
        display: inline-block;
        margin: 0px auto;
        width: 100%;
    }
    .menu {
        width: 100%;
        display: inline-block;
        text-align: center;
    }

Answer 4

您想要的是他们的样式边距：0 auto；看看这个示例代码，你就会得到它。

<style>
.wrapper{
    width:100%;
    height: 30px;
    background: black;
}
.centered_div{
    width: 200px;
    background: red;
    margin:0 auto;
}
</style>
<div class="wrapper">
    <div class="centered_div">
        test
    </div>
</div>
