Question

我在中间做了Bootstrap Navbar徽标。这是结果的图片：

但是我有1个问题：调整浏览器大小时，导航链接似乎相互重叠。

我正在寻找的是当我调整浏览器的大小时，链接保持相对彼此并且直到重叠在引导切换按钮中折叠才重叠。这里的解决方案是什么？

这是HTML和CSS

html,
body {
  height: 100%;
  width: 100%;
  font-family: 'Arial', 'Poppins', sans-serif;
  background-color: #2d2d2d;
  margin: 0;
}

.navbar {
  width: 100%;
  z-index: 999;
  background: #2d2d2d;
  ;
  margin-top: 0;
  padding: 2em;
  /* display: flex; */
}

.navbar .nav-link:hover {
  color: rgba(255, 185, 197, 0.986) !important;
}

.navbar-brand {
  transform: translateX(-50%);
  left: 50%;
  top: .1%;
  position: absolute;
}

.navbar-nav li {
  padding-right: 40px;
  font-family: 'Myriad Pro';
  font-weight: bold;
  /* display: inline-block; */
}

#mt-nav-left {
  position: absolute;
  transform: translateX(60%);
  right: 60%;
}

#mt-nav-right {
  position: absolute;
  transform: translateX(-65%);
  left: 65%;
}

#banner {
  overflow: auto;
  z-index: 998;
}

#banner img {
  width: 100%;
  object-fit: cover;
}

@media (max-width: 1024px) {
  #mt-nav-right {
    position: static;
  }
}

@media (max-width: 991px) {
  #mt-nav-left {
    position: relative;
  }
  #mt-nav-right {
    position: relative;
  }
}

Answer 1

您可以使用flex-box解决它。想法是在两个具有以下属性的列表之间放置一个空框

flex-shrink: 0;
flex-basis: 100px //(not less then the width of your logo);

看看我的片段。

.navbar-brand {
  position: absolute;
  left: 50%;
  transform: translateX(-50%);
}

.menu {
  width: 100%;
}
.menu .navbar-nav {
  flex-grow: 1;
}


/*
  THIS CLASS PREVENTS OVERLAPING
*/

.menu .separator {
  flex-grow: 1;
  flex-shrink: 0;
  flex-basis: 100px;
  max-width: 250px;
  
  background: orange;
}

<nav class="navbar navbar-expand-sm navbar-light bg-light">
      <a class="navbar-brand" href="#">Navbar</a>
      <button class="navbar-toggler" type="button" data-toggle="collapse" data-target="#navbarSupportedContent" aria-controls="navbarSupportedContent" aria-expanded="false" aria-label="Toggle navigation">
        <span class="navbar-toggler-icon"></span>
      </button>
    
      <div class="collapse navbar-collapse" id="navbarSupportedContent">
        <div class="d-flex menu">
          <ul class="navbar-nav mr-auto justify-content-end">
            <li class="nav-item active">
              <a class="nav-link" href="#">Home <span class="sr-only">(current)</span></a>
            </li>
            <li class="nav-item">
              <a class="nav-link" href="#">Link</a>
            </li>
          </ul>
          <!-- Box that prevents overlaping -->
          <div class="separator">
          </div>
          <ul class="navbar-nav mr-auto">
            <li class="nav-item active">
              <a class="nav-link" href="#">Home <span class="sr-only">(current)</span></a>

    </nav>

Answer 2

这是我使用Bootstrap 4使用导航栏指定规格的方法。

1）有两个 navbars-collapse 项目，第一个项目的两端对齐，第二个项目的默认端对齐（我们将分别称为 A 和 C 。

2）品牌（称为 B ）将使用类 mx-auto 居中，接近导航栏的效果使用下一种样式（仅在非折叠模式下使用）：

@media (min-width: 768px) {

  .navbar {
    max-height: 75px;
  }

  .navbar-brand {
    bottom: -30px;
    position: relative;
  }
}

3）我们使用Order classes管理项目（ A，B和C ）的顺序，在小屏幕设备上，该顺序为 B-> A-> C ，在大屏幕设备上将为 A-> B-> C 。我们还使用Spacing utilities p classes在项目之间添加一些填充。

这只是我的主意，您可以检查下一个示例（在全屏模式下）并使用浏览器的宽度播放。希望对您有帮助...
