水平导航栏中的等长中心对齐列表项

时间:2014-09-01 14:43:28

标签: html css

我希望创建一个延伸100%的导航栏,并为每个列表项具有相同的长度。我现在拥有的代码确实延伸了100%,但有些项目不是中心对齐的,而且#34; home"和"联系"物品有不需要的空白区域。这个问题的最佳解决方案是什么?

此外,如果你有时间,我想边框下拉菜单而不加倍边框。如果查看我的代码,您可以看到它有一个外边框,并且在单个列表项上还有一个左边框(除了第一个项目)。关于这个问题的帮助也将不胜感激。

您需要清除之前nav元素中的ulfloat

.menu{
    margin:0 auto;
    padding:0 ;/* just fine with 0 */
    text-align:center;
    clear:both; /* clear from floats ahead in the flow */
}

GCyrillus以正确的方式做到了。

您还必须从链接中删除宽度:

ul.menu a {
    cursor: pointer;
    display: block;
    color: #22674A;
    line-height: 40px;
    /* width: 140px;   remove !!*/
    text-decoration: none;
    font-weight: 500;
    font-family: 'Bree Serif', serif;
    border-left: solid 1px #22674A;
}

要删除下拉列表中的边框,请添加以下内容:

ul.menu ul a{
    border-left: none;
    border-right: none;
}
