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。
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：
HTML代码:
XML/HTML Code复制内容到剪贴板这个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：
CSS3代码:
CSS Code复制内容到剪贴板- .page-menu-wrapper > ul > li {
- position: relative;
- float: left;
- border-left: 1px solid #3d61a2;
- border-right: 1px solid #3d61a2;
