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ul
或float
:
.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;
}
