<p>The list items are wrapping because you're using percentage margins.</p>

<p>When you give the items horizontal margins of 2%, the browser calculates the length of that 2% <em>after</em> the size of the container has been determined. In other words, the percentages are not factored into the container width.</p>

<p>Therefore, when the 2% length is added to the items, the total length exceeds that of the container and wrapping occurs.</p>

<h2>Solution #1: <code>white-space: nowrap</code></h2>

<p>One way to fix the problem is by suppressing line breaks in the container using <a href="https://developer.mozilla.org/en-US/docs/Web/CSS/white-space" rel="nofollow noreferrer">the <strong><code>white-space</code></strong> property</a>. This forces all items to stay on the same line, overflowing the container if necessary.</p>

<p><div class="snippet" data-lang="js" data-hide="false" data-console="true" data-babel="false">
<div class="snippet-code">
<pre class="snippet-code-css lang-css prettyprint-override"><code>nav {
  display: flex;
  align-items: center;
  justify-content: space-between;
  border: 1px dashed black;   /* for demo only */
}

nav img {
  height: 60px;
}

.links {
  margin: auto;
  white-space: nowrap;     /* NEW */
  padding: 0;              /* optional; remove default indentation on list elements */
  border: 1px dashed red;  /* for demo only */
}

nav ul li {
  display: inline-block;
  list-style: none;
  margin: 0 2%;
}</code></pre>
<pre class="snippet-code-html lang-html prettyprint-override"><code>&lt;nav&gt;

  &lt;/ul&gt;
&lt;/nav&gt;</code></pre>
</div>
</div>
</p>

<hr>

<h2>Solution #2: Don't use percentage values</h2>

<p>If you use any value other than percentages, the list items won't wrap because, unlike percentage values, they can expand the container for accommodation.</p>

<p><div class="snippet" data-lang="js" data-hide="false" data-console="true" data-babel="false">
<div class="snippet-code">
<pre class="snippet-code-css lang-css prettyprint-override"><code>nav {

  border: 1px dashed red;  /* for demo only */
}

nav ul li {
  display: inline-block;
  list-style: none;
  margin: 0 1em;            /* adjustment */

  &lt;/ul&gt;
&lt;/nav&gt;</code></pre>
</div>
</div>
</p>

<hr>

<h2>Solution #3: Use flexbox</h2>

<p>An initial setting of a flex container is <code>flex-direction: row</code> and <code>flex-wrap: nowrap</code>. This means that flex items will line up horizontally and cannot wrap.</p>

<p><div class="snippet" data-lang="js" data-hide="false" data-console="true" data-babel="false">
<div class="snippet-code">
<pre class="snippet-code-css lang-css prettyprint-override"><code>nav {
  display: flex;
  align-items: center;
  justify-content: space-between;
  border: 1px dashed black;   /* for demo only */
}

nav img {
  height: 60px;
}

.links {
  margin: auto;
  padding: 0;              /* optional; remove default indentation on list elements */
  border: 1px dashed red;  /* for demo only */
  display: flex;           /* new */
}

nav ul li {
  display: inline-block;
  list-style: none;
  margin: 0 1em;            /* adjustment; avoid percentage margins on flex items;
                               see this post:
                               https://stackoverflow.com/q/36783190/3597276 */

<pre class="snippet-code-html lang-html prettyprint-override"><code>&lt;nav&gt;

<p>I'm trying to create a navigation bar, a logo at the left and the links centered in the remaining space. I followed the instructions in this thread:
<a href="https://stackoverflow.com/questions/32551291/in-css-flexbox-why-are-there-no-justify-items-and-justify-self-properties/33856609#33856609">In CSS Flexbox, why are there no &quot;justify-items&quot; and &quot;justify-self&quot; properties?</a>
and used <code>margin:auto;</code> for the <code>ul</code> in order to get it centered. This worked fine so far but when I add <code>margin</code> or <code>padding</code> anywhere inside the <code>ul</code> the list of links wraps. I tried <code>box-sizing:border-box;</code> for the <code>ul</code> but no success. How can I fix this?
