Question

我有一个菜单如下，但我有一些问题。例如，在全尺寸屏幕中，菜单选项不在其所在部分的中间顶部。另一个问题是，当屏幕处于手机大小和汉堡包时，我不知道如何移除黑条图标是可见的。

Answer 1

不确定中间顶部，但另一部分应该有效。

.navbar-inverse .navbar-nav > li > a:hover, .navbar-inverse .navbar-nav > li > a:focus, .navbar-inverse .navbar-nav > li > a{
  padding: 10px !important;
} 

.navbar-header {
    background-color: white; //or inherit whatever you like
}


.navbar-toggle.collapsed {
    background-color: black;
}

Answer 2

中间对齐菜单的

使用像

这样的CSS

.navbar-inverse .navbar-nav > li > a:hover, .navbar-inverse .navbar-nav > li > a:focus, .navbar-inverse .navbar-nav > li > a{
  padding: 10px !important;
}
.navbar-inverse {
  position: absolute;
  top:50%;
  width:100%;
  left: 0
}

如果要删除背景颜色，请使用css

        @media only screen and (max-width : 480px) {
.navbar-inverse{
  background: transparent;
}
  .navbar-inverse .navbar-toggle:hover, .navbar-inverse .navbar-toggle:focus{
    background: transparent;
  }
  .navbar-inverse .navbar-toggle{
    border: 0px none;
  }
    .navbar-inverse .navbar-toggle .icon-bar {
    background: #666;
}
}

希望这会对你有所帮助

我在桌面上显示时将菜单项目放在中心，然后当最小化到手机大小时，背景栏变为白色，然后汉堡包图标将变为黑色

我已经使用bootstrap工作了很多，所以我建议你用你自己的课程扩展他们原来的风格而不是覆盖everthing。我的sugestion基于flexbox，并使用自定义类作为根据需要使事情工作的方式。

检查一下，希望它有所帮助。（：

JSFiddle Link：https://jsfiddle.net/ce7L0nez/

CSS：

<script>
    var num = 0;
    var count = 0;

    while (count != 20) {
        num++;
        count = 0;

        for (var i = 1; i <= 20; i++) {
            if (num % i == 0) {
                count++;
            }
        }
    }

    console.log(num);
    console.log(count);
</script>

HTML：

.center-md-content {
    display: flex!important;
    align-items: center;
    justify-content: center;
}
.center-md-content .navbar-nav {
    float: none;
}

@media only screen and (max-width : 768px) {
    .sm-no-background {
        background-color: transparent;
    }
    .sm-no-background .navbar-header {
        margin-left: auto;
    }
    .sm-no-background .navbar-toggle .icon-bar {
        background-color: #333;
    }
    .sm-no-background .navbar-toggle {
        border: 0;
    }
    .sm-no-background .navbar-toggle:hover .icon-bar {
        background-color: #FFF;
    }
}

如何只显示菜单的汉堡包图标而不是背景栏并在中上方显示菜单选项？
