Pure-CSS解决方案： Fiddle
使用.main_navigation>li:hover .balloon代替.main_navigation>li a:hover + .balloon，即使鼠标悬在气球上，也可确保气球保持打开状态。
然后添加，
.balloon:before {
display: block;
content: "";
width: 100%;
height: 10px;
position: absolute;
top: -10px;
left: 0;
}
在菜单和气球之间添加一个不可见的块。

当你的鼠标命中时，你的菜单和下拉菜单之间会有间隙。
如果您想保持视觉感受，请使用https://github.com/briancherne/jquery-hoverIntent
或者，如果您只想尝试较小的js，请调整How to delay hiding of a menu with Jquery Dropdown Menu?，如下所示（您可以将1000更改为更大或更小的值）。
$('.main_navigation a').bind('mouseout', function()
{
var menu = this;
setTimeout(function()
{
$(menu).parents('li').children('ul').hide();
}, 1000);
});
