大家!!我在codepen中构建一个非常简单的页面，我对这些东西很新。我想将导航栏上的所有选项对齐在同一行中。我甚至不知道为什么他们看起来像这样。我也想对页面末尾的社交媒体图标做同样的事情。这是我的笔https://codepen.io/maria_punchio/pen/mWggYO/。

改变这个：

a {
  overflow: hidden;
  display: inline-block;
  margin-bottom: px;
  width: calc(50% - 4px);
  margin-right: 8px;
}

对此：

a {
  overflow: hidden;
  display: inline-block;
  margin-bottom: px;
  width: calc(33% - 4px);
  margin-right: 8px;
}

并改变这一点：

@media screen and (min-width: 80em) {
  a {
    width: calc(40% - 6px);
  }
  a:nth-of-type(2n) {
    margin-right: 8px;
  }
  a:nth-of-type(4n) {
    margin-right: 0;
  }
}

到此：

@media screen and (min-width: 80em) {
  a {
    width: calc(33% - 6px);
  }
  a:nth-of-type(2n) {
    margin-right: 8px;
  }
  a:nth-of-type(4n) {
    margin-right: 0;
  }
}

.topnav {
background-color: #586882;
overflow: hidden;}

.topnav a {
float: left;
display:block; margin-left: 5px;;
color: #f2f2f2;
text-align: center;
padding:16px;
text-decoration: none;
font-size: 17px;}
  <div class="container-fluid">
    <div class="topnav">
<a href="#div_id">ABOUT</a>
<a href="#div_id2">PORTFOLIO</a>
<a href="#div_id3">CONTACT ME</a>
    </div>

这是代码...... 

   <style>.topnav {
  background-color: #586882;
  overflow: hidden;}

 .topnav a {
  float: left;
   display:block; margin-left: 5px;;
     color: #f2f2f2;
   text-align: center;
    padding:16px;
   text-decoration: none;
        font-size: 17px;}</style>

快速解决方法是添加

width: 33%;
margin: 0;

到你的css中的.topnav a。

但是我建议你看一下flexbox是如何工作的，因为这会更敏感。

我个人非常喜欢this guide。
