如何使用bootstrap创建带有CSS形状的navbar？

Question

我需要像下面那样创建导航栏。

我使用了导航栏的背景图片，但它会显示在标签和移动视图中，例如this

FYI， 标签和移动响应将如下所示（仅设计不是文字）...

我需要在没有背景图片的情况下创建它。你能帮帮我吗...

Answer 1

表示我使用skewX

的形状

body {
  padding-top: 50px;
  background: url(https://images.pexels.com/photos/74775/pexels-photo-74775.jpeg?w=940&h=650&auto=compress&cs=tinysrgb);
  background-size: cover;
}

.navbar.navbar-inverse {
  background: rgba(0, 0, 0, 0.45);
  border: none;
}

.navbar-brand {
  position: relative;
}

.navbar-brand:after {
  content: '';
  position: absolute;
  right: -100%;
  background: #fff;
  left: -500px;
  height: 100%;
  top: 0;
  z-index: -1;
  transform: skewX(-45deg);
}

.navbar-collapse .navbar-nav {
  float: right;
}

@media (max-width: 767px) {
  .navbar-collapse .navbar-nav {
    float: none;
  }
}
