我要问的问题是，是否要使该菜单成为产品"按钮的下拉菜单，其样式样式与导航栏的其余部分类似(例如，悬停颜色和背景颜色).我将如何使用CSS来实现这一目标. 有问题的CSS的新HTML正在...
My question to the point is if I was to make this menu a drop down menu for the "The products" button following a similar style pattern (such as hover colours and background colours) to the rest of the navbar. how would I go about with CSS to achieve this. The new HTML for the css in question being...
<div class="navbar">
<ul class="horizontal">
<li><a class="first" href="#">Home</a></li>
<li><a href="#">About Us</a></li>
<li><a href="#">Our Products</a></li>

推荐答案
我不太确定这是否是您的意思，也许它需要一些样式调整.
I am not quite sure if this is what you mean, maybe it needs some style adjustment.
问题是您的子菜单列表应位于主菜单的列表项内.像这样:
The thing is that your submenu list should be inside the list item of the main menu. Like this:
<ul>
<li>Item
<ul>
<li>...</li>
</ul>
</li>
</ul>
在您的代码中(并优化了CSS)，这是我想出的: HTML
Using that in your code (and optimized the CSS), this is what I came up with: HTML
<div class="navbar">
<ul class="horizontal">
<li><a href="#">Home</a></li>
<li><a href="#">About Us</a></li>
<li><a href="#">Our Products</a>
<ul>
<li><a href="#">Apple</a></li>
<li><a href="#">HTC</a></li>
<li><a href="#">Nokia</a></li>
<li><a href="#">Samsung</a></li>
</ul>
</li>
<li><a href="#">Environment</a></li>
<li><a href="#">Latest News</a></li>
<li><a href="#">Contact Us</a></li>
</ul>
</div>
CSS:
.horizontal {
list-style-type:none;
margin:40 auto;
width:640px;
padding:0;
overflow:hidden;
}
.horizontal > li {
float:left;
}
.horizontal li ul {
display: none;
margin: 0;
padding: 0;
list-style: none;
position: relative;
width: 100%;
}
.horizontal li:hover ul {
display: block;
}
.horizontal li a {
display: block;
text-decoration:none;
text-align:center;
padding:22px 10px;
font-family:Arial;
font-size:8pt;
font-weight:bold;
color:#FFFFFF;
text-transform:uppercase;
border-right:1px solid #607987;
background-color:#300000;
letter-spacing:.08em
}
.horizontal li a:hover {
background-color:#680000;
color:#a2becf
}
.horizontal li:first-child a { border-left:0; }
.horizontal li:last-child a { border-right:0; }
就像说的那样，您可能需要更改某些样式！
Like said, you may need to change some of the styles!
