Question

我在 wordpress 上使用子主题，出于某种原因，导航栏不适合 div“标题”。我尝试了所有部分的 height: 100% 。

.main-nav {
    float: right;
    border: none;
    position: relative;
    margin: 0px auto;
    padding: 0px;
    clear: none;
    height: 100%;
}
.menu, .menu ul {
    text-decoration: none;
    text-shadow: 0px;
    margin: 0px auto;
    padding: 0px;
    clear: none;
    height: 100%;
}
.menu li a:link {
    border: none;
    color: #353535;
    background-color: white;
    text-transform: lowercase;
    font-family:'Open Sans', sans-serif;
    text-shadow: 0px 0px 0px;
    font-weight: normal;
    font-size: 15px;
    background-image: none;
}
.menu li a:visited {
    border: none;
    color: #353535;
    background-color: white;
    text-transform: lowercase;
    font-family:'Open Sans', sans-serif;
    text-shadow: 0px 0px 0px;
    font-weight: normal;
    font-size: 15px;
    background-image: none;
}
.menu li a:hover {
    border: none;
    color: DeepPink;
    text-transform: lowercase;
    background-color: white;
    font-family:'Open Sans', sans-serif;
    text-shadow: 0px 0px 0px;
    font-weight: normal;
    font-size: 15px;
    background-image: none;
}
.menu li a:active {
    border: none;
    color: DeepSkyBlue;
    text-transform: lowercase;
    background-color: white;
    font-family:'Open Sans', sans-serif;
    text-shadow: 0px 0px 0px;
    font-weight:normal;
    font-size: 15px;
    background-image: none;
}

根据请求，HTML:

<div id="header">       
<div id="logo">
    <a href="http://acjdesigns.com/"><img src="http://acjdesigns.com/wp-content/uploads/2014/01/cropped-copy-Logo-012.png" width="250" height="54" alt="ACJ Designs"/></a>
    </div><!-- end of #logo -->
    <div class="main-nav">
      <ul class="menu">
        <li class="current_page_item"><a href="http://acjdesigns.com/">Home</a></li>
        <li class="page_item page-item-34"><a href="http://acjdesigns.com/bio">bio</a></li>
        <li class="page_item page-item-39"><a href="http://acjdesigns.com/graphics">graphics</a></li>
        <li class="page_item page-item-101"><a href="http://acjdesigns.com/photography-2">photography</a></li>
        <li class="page_item page-item-41"><a href="http://acjdesigns.com/other-works">other works</a></li>
   </ul>
</div>
</div><!-- end of #header -->

我没有将标题 div 设置为高度，所以这可能是问题所在？任何帮助都会很棒。提前致谢!

您有两种通用方法:在 all elements down from body 上设置 height:100%;

html {height:100%;}
body {height:100%;}
...  
#header {height:100%;}

或

使用absolute positioning

#header{
  position: absolute;
  top: 0;
  bottom: 0;
  left: 0;
  width: 400px;
}
/* you must now move your content out of the way of the header, or it will sit on top */

#content{
  margin-left: 420px;
}
