我正在尝试将导航线的宽度扩展到整个宽度,而不仅仅是覆盖链接。我认为第7行(包括)上的代码/样式表正在干扰第12-21行以下的html样式标签。但是,如果我删除此行,那么黑暗的背景就会消失,并且链接将显示为列表。

A
您在a
链接上有一个边框,而不是.navbar-nav
。 a
链接样式将仅覆盖可点击部分,而不覆盖整个导航区域。
要解决此问题,如果按照以下代码从样式中删除a
,则它将覆盖导航的整个宽度。
.navbar-nav {
border-top:3px solid #DB9842;
border-bottom: 3px solid #DB9842;
}
由于.navbar-nav
元素上的ul
样式也处于创建双边框的状态。为了防止这种情况,我添加了以下代码,以便仅将边框应用于导航区域,而不应用于ul
。
.navbar-nav ul {border:none;}
