【问题讨论】：

请查看您的最后一段。有很多重复。

标签： javascript java html css navbar

【解决方案1】：

navbaritems

您的导航栏项目在那里，它们只是白色文本。 (#FFF)。

我更改了以下内容，它们更加明显。

.navbar-links ul li a {
    text-decoration: none;
    display: block;
    color:#01C7F5;
    padding: 35px 20px;
    font-family: GentiumBookBasic;
    font-size:21px;
}

【讨论】：

因为我上传到codepen没有背景，不是这样
我看了你的codepen。将屏幕最小化到启用汉堡导航栏菜单的位置。更改文本颜色后，您的菜单项现在会显示。
