CSS3实现多功能下拉菜单 带分享按钮菜单

今天要分享的这款菜单是基于CSS3的下拉菜单,功能非常强大,下拉菜单中不仅拥有背景色渐变的菜单项,而且还带有分享按钮的菜单项,为了让菜单更加美观,每一个菜单项都带有非常漂亮的小图标,而且在下拉菜单中还有鼠标滑过缩进的动画特效,具体可以点击DEMO查看。

接下来我们来具体解说一下实现这款CSS3下拉菜单原理和过程,代码主要是HTML和CSS。

首先是HTML代码,主要是两部分,左侧的下拉菜单项和右侧的分享按钮菜单,分别用了一个ul li列表:

<ul class=”menu-function”>
<li>
<a href=”" title=”">CATEGORIES</a>
<ul class=”dropdown-menu categories”>
<li><a href=”" title=”">Design</a></li>
<li><a href=”" title=”">Freebies</a></li>
<li><a href=”" title=”">Tutorials</a></li>
<li><a href=”" title=”">Coding</a></li>
<li><a href=”" title=”">Inspiration</a></li>
<li><a href=”" title=”">WordPress</a></li>
<li><a href=”" title=”">Resources</a></li>
</ul>
</li>
<li><a href=”" title=”">SHOP</a></li>
<li id=”search”>
<a href=”#search” title=”">SEARCH</a>
</li>
<li id=”search-hidden”>
<input type=”text” name=”" id=”"><a href=”#search-hidden” title=”"></a>
</li>
</ul>
<ul class=”menu-share”>
<li>
<a href=”" title=”">FOLLOW US</a>
<ul class=”dropdown-menu follow”>
<li><a href=”" title=”">RSS</a></li>
<li><a href=”" title=”">Twitter</a></li>
<li><a href=”" title=”">Facebook</a></li>
<li><a href=”" title=”">Google+</a></li>
<li><a href=”" title=”">Dribbble</a></li>
</ul>
</li>
<li>
<a href=”" title=”">SHARE</a>
<ul class=”dropdown-menu share”>
<li><a href=”" title=”">Facebook</a></li>
<li><a href=”" title=”">Twitter</a></li>
<li><a href=”" title=”">Google+</a></li>
</ul>
</li>
</ul>

这个ul结构支撑了下拉菜单的基本骨架,应该还算普通。

接下来是CSS3代码,是实现这款CSS3下拉菜单的关键:

.page-menu-wrapper > ul > li {
position: relative;
float: left;
border-left: 1px solid #3d61a2;
border-right: 1px solid #3d61a2;
margin-right: -1px;
}
.menu-function {
float: left;
}
.menu-share {
float: right;
}
.page-menu-wrapper > .menu-function > li:first-child {
border-left: none;
}
.page-menu-wrapper > .menu-share > li:last-child {
border-right: none;
}
.page-menu-wrapper a {
position: relative;

padding: 0 15px;

}
.page-menu-wrapper > ul > li:hover > a {

}
.page-menu-wrapper > ul > li:hover .dropdown-menu {

.dropdown-menu.categories a {

}
#search:target a[href="#search"] {

}
