水平CSS菜单

Question

我是一名网页设计师爱好者，在我目前正在从事的一个项目中，我一直面临着一些编码问题。我的目标是从这个网页中重现菜单样式：http://blueowlcreative.com/wp/aqua/。我希望它是全宽和居中的。这就是我到目前为止所做的：

这是html：

<!-- Menu -->
<div id="menu">

<ul id="menu-bar">
    <li><a href="#">Home</a></li>

    <li><a href="#">Empresa</a>
        <ul>
            <li><a href="#">Nossa história</a></li>
            <li><a href="#">Sustentabilidade</a></li>
            <li><a href="#">Compromisso social</a></li>
        </ul>
    </li>

    <li><a href="#">Produtos</a></li>
    <li><a href="#">Cotação</a></li>

    <li><a href="#">Qualidade</a>
        <ul>
            <li><a href="#">Política da qualidade</a></li>
            <li><a href="#">Certificados</a></li>
        </ul>
    </li>

    <li><a href="#">Parceiros</a>
        <ul>
            <li><a href="#">Clientes</a></li>
            <li><a href="#">Fornecedores</a></li>
        </ul>
    </li>

    <li><a href="#">Contato</a></li>

</div><!-- end menu -->

这是CSS：

html[xmlns] #menu-bar {

* html #menu-bar {

Answer 1

首先，您应该关闭您的</ul>标记。

然后你应该在你的#菜单中添加一些样式。

top: 0;
left: 0;

将您的position:relative;更改为position:fixed;

#menu {
  width: 100%;
  margin: 0;
  padding: 0;
  top: 0;
  left: 0;
  height: 60px;
  line-height: 100%;

  background: #494949;
  background: linear-gradient(top,  #494949,  #353535);
  background: -ms-linear-gradient(top,  #494949,  #353535);
  background: -webkit-gradient(linear, left top, left bottom, from(#494949), to(#353535));
  background: -moz-linear-gradient(top,  #494949,  #353535);
  border: solid 0px #6d6d6d;
  position:fixed;
  z-index:999; 
  }

在#菜单栏中添加float: right;

#menu-bar {
  width: 937px;
  margin: 0 auto;
  height: 60px;
  line-height: 100%;
  float: right;
  }
