【中文标题】导航栏没有变成汉堡或响应【英文标题】:Navbar not turning into a burger or being responsive 【发布时间】:2018-05-10 13:17:58 【问题描述】:我已经尝试自定义我的导航栏,我已经从引导站点复制了 3.0 的基本导航栏。现在,我的导航没有变成汉堡导航,我用于导航棒的自定义背景图像,标志棒,但导航按钮消失了。我假设它们会在背景图像下方或屏幕外变成汉堡。

【问题讨论】:
检查this可能有帮助 那是什么?</button>max-width: 100%
【参考方案1】:
您的 html 存在很多问题。一些元素被注释掉了,多余的结束标签如</li>
或</ul>
,你的html中还有max-width:100%
。那里没有生意。
关于您的问题,问题在于您设置了.navbar width:980px
,因此当您在小于980px
的屏幕上时,并非所有.navbar
都可见(导航栏的右侧不适合在屏幕内)所以汉堡菜单在那里但不可见,因为navbar
比屏幕大
如果您希望您的 .navbar 为 980 像素但也具有响应性(屏幕较小时缩放),请使用 max-width:980px
见下文

【讨论】:
谢谢,汉堡现在出现了,小问题你知道如何将我的自定义背景图像更改为更小的纯色背景吗? 您可以为此使用媒体查询。例如@media only screen and (max-width: 767px) .navbar background-image:none;background-color:red;
接受!我已将其添加到我的 CSS 中,但没有任何改变。
@LukeSciberras 很好。您希望您的背景在多大的屏幕尺寸下从图像变为颜色?【参考方案2】:
我也遇到了同样的问题。我的解决方案是在 css 中为图标栏设置背景颜色:
.icon-bar
background-color: black;
