如何删除水平固定导航栏中列表项之间的“间隙”

Question

所以我创建了一个导航栏，我已经开始使用水平导航了。 但是我在导航栏之间有这些“间隙”，如下图所示，但我仍然可以在这些间隙之间点击。

这是JSFiddle（SCSS无法工作所以我使用编译的CSS）：

这是我正在使用的导航代码，变量只是我正在使用的颜色：

HTML：

<nav id="nav">
    <span class="brand">Brand Name</span>
    <ul>
        <li><a href="about.html">About <i class="fa fa-angle-down"></i></a></li>
        <li><a href="portfolio.html">Portfolio</a></li>
        <li><a href="contact.html">Contact Us</a></li>
    </ul>
    <a class="nav-bars"><i class="fa fa-bars"></i></a>
</nav>

SCSS（Sass）：

Answer 1

这应该可以解决问题，你可以在下面更改CSS

更新了codepen： http ：//codepen.io/anon/pen/QKKbyZ

nav ul li {
  /* display: inline-block;       remove, not needed as you use flex on its parent  */
  list-style: none;
  cursor: pointer; }
  nav ul li a {
    color: #444;
    text-decoration: none;
    padding: 22.5px 20px;
    /* margin: 10px 0;             remove, creates additional gaps    */

Answer 2

从'nav ul li'中删除边距并从'a.nav-bars'中删除display：inline-block
