Bootstrap Navbar，背景仅在右侧而不是整个宽度

Question

使用引导程序的导航栏，我只使用右侧的下拉切换器图标。我想要一个宽度只覆盖右侧部分而不是整个宽度的背景。任何见解将不胜感激。

尝试 1 和 2：

试图得到：

.menu {
  font-family: header;
  color: white !important;
  font-size: 3rem;
  background-color: rgba(0, 0, 0, 0.3);
}

.menu-bg {
  background-color: rgba(0, 0, 0, 0.3);
}

body {
  background: #333 !important;
}

Answer 1

请尝试

.menu-bg {
    width: 250px;
}

Answer 2

这是一个工作示例。要点是使用position:absolute 并将宽度设置为下拉，以便它会粘在右边。

.menu {
font-family: header;
color: white !important;
font-size: 3rem;
background-color: rgba(0, 0, 0, 0.3);
}

.menu-bg {
    background-color: rgba(0, 0, 0, 0.3);
}
#navbarSupportedContent {
  width:150px;
  position: absolute;
  right:0px;
  top:100%;
}

.dropdown-wrap {
  position: relative;
}

仅：

.menu-bg {
    background-color: rgba(0, 0, 0, 0.3);
    display: inline-block;
}
