http://www.ashlandmediagroup.com/menu-test/menu.html 最后一个菜单项的悬停状态需要延伸到菜单的末尾，但这会导致菜单在放大和缩小时中断。

我对其他菜单也有同样的问题，想知道是否有解决方案。

这是我的代码：

/* main navbar */

ul#main-menu {
  float: left;
  font-size: 14px;
  font-family: "arial";
  text-transform: uppercase;
  margin: 0;
  width: 100%;
}

ul#main-menu {
  height: 33px;
  list-style: none outside;
  border-radius: 5px;
  -moz-border-radius: 5px;
  -webkit-border-radius: 5px;
  behavior: url(http://www.ashlandmediagroup.com/menu-test/border-radius.htc);
}

ul#main-menu {
  background: url(nav-back.jpg) repeat-x;
}

ul#main-menu li {
  float: left;
  height: 33px;
}

ul#main-menu li a {
  text-decoration: none;
  color: #fff;
  display: block;
  padding: 8px 20px 9px 20px;
  background: url('../images/nav-divider.jpg') no-repeat;
  height: 16px;
}

ul#main-menu li:first-child a {
  padding: 8px 10px 9px 26px;
  background: none;
}

ul#main-menu li:first-child.active {
  border-radius: 5px 0 0 5px;
}

li.wwd span,
li.wwd:hover span {
  display: block;
  background: url('../images/what-we-do-hover.png') no-repeat 135px 0;
  width: 165px;
}

ul#main-menu>li:hover,
ul#main-menu li.active {
  background: url(nav-hover.jpg) repeat-x;
}

ul#main-menu {}

li.wwd:hover {}

ul#main-menu li:last-child {
  /*
        border-radius : 0px 5px 5px 0px;
    	margin-right: 0px;
    */
}

ul#main-menu li:last-child a {}

ul#main-menu li:last-child a:hover {}

/* sub-menu: main categories */

#sub-menu {
  z-index: 100;
}

ul#main-menu ul {
  position: relative;
  left: -9999px;
  background: rgba(255, 255, 255, 0);
}

ul#main-menu ul li {
  /* Introducing a padding between the li and the a give the illusion spaced items */
  float: left;
}

ul#main-menu ul li a {
  height: auto;
}

ul#main-menu ul#sub-menu a {
  white-space: nowrap;
  /* Stop text wrapping and creating multi-line dropdown items */
}

ul#main-menu li:hover ul,
ul#main-menu li.active ul {
  /* Display the dropdown on hover */
  left: 0px;
  /* Bring back on-screen when needed */
}

ul#main-menu li:hover a {
  /* These create persistent hover states, meaning the top-most link stays 'hovered' even when your cursor has moved down the list. */
  text-decoration: none;
}

ul#main-menu li:hover ul a {
  /* The persistent hover state does however create a global style for links even before they're hovered. Here we undo these effects. */
  text-decoration: none;
}

ul#main-menu li:hover ul li a:hover {
  /* Here we define the most explicit hover states--what happens when you hover each individual link. */
}

ul#main-menu ul#sub-menu {
  height: 51px;

  border-radius: 0 0 5px 5px;

您当前的布局目标并不完全清楚，但这是一种解决方案。

  1. 从; id="main-menu" width_ 100%到auto;

  2. id="sub-menu" width从更改700px;为665px;

jsFiddle 演示

编辑：这种替代方法保留了您必须说明的当前宽度，您可以将最后一个导航按钮悬停区域“扩展”到可用的最大宽度。

请注意，在这个 jsFiddle 中，您会看到需要进行调整以“填补空白”，即当前实时 CSS 在使用时使用100%的，但您可以将其更改为您需要的确切像素值。

jsFiddle DEMO v2 100% 宽度

jsFiddle DEMO v3 像素宽度

提醒：v2 和 v3 中使用的边框增加了面包屑的大小。
