Question

我在使用HTML，CSS和JavaScript创建两行导航栏时遇到问题。

这就是我希望导航栏显示的样子：

但是，徽标似乎重叠了右侧的链接，而这并不是我想要的。

我的HTML：

<div id="top-bar">
    <div class="container">
      <ul>
        <li><a href="#"><i class="fab fa-facebook"></i>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; <i class="fab fa-twitter"></i> &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;<i class="fab fa-instagram"></i></a> </li>
        <li style="padding:0;"><a href="#" style="position: absolute; z-index:1; top:0;"><img src="https://via.placeholder.com/250x115" alt=""  width="100%"></a>
          <li><a href="#">01283 575 671</a></li>
          <li><a href="#">Join Now </a></li>
      </ul>
    </div>
  </div>
  <div class="nav-bg">
  <div class="container">
    <ul id="nav">
      <li><a href="#" class="nav_first">Facilties</a></li>
      <li><a href="#">Timetable</a></li>
      <li><a href="#">Blog</a></li>
      <li><a href="#" class="nav_blank"></a></li>
      <li><a href="#">The Team</a></li>
      <li><a href="#">Events</a></li>
      <li><a href="#" class="nav_last">Contact Us</a></li>
    </ul>
  </div>
    </div>

我的CSS：

* { box-sizing:border-box }

body {
    margin: 0px;
  font-family: 'Montserrat', sans-serif;
}

.container {
  padding-right: 15px;
  padding-left: 15px;
  margin-right: auto;
  margin-left: auto;
}
@media (min-width: 768px) {
  .container {
    width: 750px;
  }
}
@media (min-width: 992px) {
  .container {
    width: 970px;
  }
}
@media (min-width: 1200px) {
  .container {
    width: 1170px;
  }
}

#top-bar {
    float: left;
    -webkit-border-radius: 5px;
    -moz-border-radius: 5px;
    border-radius: 0px;
    overflow: hidden;
    width:100%;
    min-width: 650px;
    min-height: 50px;
  background: #FFDE00;
}

#top-bar div ul {
    margin:0;
    padding:0;
    list-style:none;
}

#top-bar div ul li {
    float:left;
    padding: 15px 15px;
    width: 20%;
  background: #FFDE00;
    font-weight:500;
  text-transform:uppercase;

}

#top-bar div ul li:first-child{
  width:40%;
}

#top-bar div ul li:last-child{
  background:#081F2D;
}


#top-bar div ul li a {
    display: block;
    color:#081F2D;
    text-decoration:none;
    text-align: center;
    font-size:17px;
}

#top-bar > div > ul > li:nth-child(4) > a{
  color:#FFDE00;
}

#nav {
  text-align: justify;
  min-width: 500px;
  font-size: 0;
  padding-left:0;
}

.nav-bg{
  background-color: #EEEEEE;
}
#nav:after {
  content: '';
  display: inline-block;
  width: 100%;
}
#nav li {
  display: inline-block;

  background-color: #ccc;
}
#nav a {
  padding: 15px 40px;
  display: block;
  font-size: 1rem;
  text-align: center;
  color:#081F2D;
  text-transform:uppercase;
  font-weight:600;
  text-decoration: none;
  background-color: #EEEEEE;
}
#nav .nav_blank { width: 250px; padding: 15px 0; }
#nav .nav_first { padding-left: 0; }
#nav .nav_last { padding-right: 0; }

通过实现CSS网格，按如下所示重做您的结构

CSS部分：

 #parent_column
{
  grid-template-columns:1fr 0.61fr 1fr;
  display: grid;
  width: 100vw;
  height: 20vh;
}

#first_column
{
  grid-column: 1;
  display:grid;
  grid-template-rows: 1fr 1fr;
}

#second_column
{
  grid-column: 2;
}

#third_column
{
  grid-column: 3;
  display:grid;
  grid-template-rows: 1fr 1fr;
}

HTML为

<div id="parent_column">
  <div id="first_column">
    <div style="background-color: rebeccapurple;">Top Bar Content on Left</div>
    <div style="background-color: gold;">Bottom Bar Content on Left</div>
  </div>
  <div id="second_column">
    <a href="#" style="position: absolute; z-index:1; top:0;"><img src="https://via.placeholder.com/250x115" alt=""
        width="100%"></a>
  </div>
  <div id="third_column">
    <div style="background-color: red;">Top Bar Content on Left</div>
    <div style="background-color: pink">Bottom Bar Content on Left</div>
  </div>
</div>

结果：现在87.85％的浏览器都支持CSS-Grid，对于IE浏览器，您需要添加前缀ms-

除了使用grid模板或将导航吐到左右两个区域之外，我看不到其他任何选择。

我建议使用div和span而不是ul和li。另外，将所有内容分为3部分-左，中和右。这将使您的任务更容易完成，如下所示。

HTML：

<body>
  <div id="top-bar">
    <div class="container">
      <div class="left-right-container">
        <div class="left-container">
          <span><a href="#"><i class="fab fa-facebook"></i>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; <i class="fab fa-twitter"></i> &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;<i class="fab fa-instagram"></i></a> </span>
        </div> 
        <div class="right-container">
          <span><a href="#">01283 575 671</a></span>
          <span><a href="#">Join Now </a></span>
        </div>
      </div> 
      <div class="center-container">
        <span style="padding:0;"><a href="#" style="position: absolute; z-index:1; top:0;"><img src="https://via.placeholder.com/250x115" alt=""  width="100%"></a></span>
      </div>
    </div>
  </div>
  <div class="nav-bg">
  <div class="container">
    <div class="left-right-nav">
      <div class="left-nav">
        <div>
          <span><a href="#" class="nav_first">Facilties</a></span>
          <span><a href="#">Timetable</a></span>
          <span><a href="#">Blog</a></span>
        </div>
      </div>
      <div class="right-nav">
        <div>
          <span><a href="#">The Team</a></span>
          <span><a href="#">Events</a></span>
          <span><a href="#" class="nav_last">Contact Us</a></span>

    <div class="center-nav">
