<p>If you want two <code>div</code> side-by-side then either use <code>float</code> OR use <code>display: inline-block</code>.</p>

<p>In your case I have defined <code>float: left;</code> for <code>#leftNavSection</code></p>

entityMap|blocks|key|5bgn6|text|简单地让你的图像向左浮动。图像是一个内联元素，它占据了整个线条的宽度。您的div是浮动的，导致它自己折叠，但被inline元素阻止上升到顶部。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|btods|删除适用于内联元素的vertical-align:top原因，而不是块级别的原因，如div。|offset|length|style|CODE|ei7ac^0|0|A|I|16|3|0^^$0|$]|1|@$2|3|4|5|6|7|8|J|9|@]|A|@]|B|$]]|$2|C|4|D|6|7|8|K|9|@$E|L|F|M|G|H]|$E|N|F|O|G|H]]|A|@]|B|$]]|$2|I|4|-4|6|7|8|P|9|@]|A|@]|B|$]]]]

<p>As I saw you were already using <code>float:right</code> on your <code>rightNavSection</code>, I went ahead and added <code>float:left</code> to your <code>leftNavSection</code>, fixing the issue. Here's the <a href="https://jsfiddle.net/ynnhcvxL/" rel="nofollow">JSFiddle</a> and here's the CSS, the only thing I changed:</p>

<pre><code>#navbar {
    width: 100%; 
    font-family: Arial; 
    vertical-align: top; 
    background-color: red;
    display: inline-block;
}

#leftNavSection {
  float: left;
}

#rightNavSection {
   float:right;
}
</code></pre>

<p>As you can see, I also added <code>display:inline-block</code> to the <code>navbar</code>'s CSS in order to get it to display properly. Without it, the red background wouldn't show.</p>


entityMap|blocks|key|10vc7|text|我建议使用flex-box，因为这是最简单的方法。|type|unstyled|depth|inlineStyleRanges|offset|length|style|CODE|entityRanges|data|2dcfl|​|4pj8k|#navbar+{

<p>I suggest using <code>flex-box</code> as it's the simplest method to do this.</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>#navbar {
  width: 100%;
  font-family: Arial;
  background-color: red;
  display: flex;

#leftNavSection,
#rightNavSection {
  background-color: yellow;
}</code></pre>
<pre class="snippet-code-html lang-html prettyprint-override"><code>&lt;div id="navbar"&gt;
  &lt;div id="leftNavSection"&gt;
    &lt;img alt="Logo" width="300" src="/assets/main_logo-791a416e4f99d38a339debb8dcebd7361d4172919425ace42ba2ce90336218e2.png"&gt;
  &lt;/div&gt;
  &lt;div id="rightNavSection"&gt;
    Logged in as M. Bison
    &lt;a href="/users/edit"&gt;Edit&lt;/a&gt;
    &lt;a rel="nofollow" data-method="delete" href="/logout"&gt;Log Out&lt;/a&gt;
  &lt;/div&gt;
&lt;/div&gt;</code></pre>
</div>
</div>
</p>


entityMap|blocks|key|3eafp|text|你也可以使用这个|type|unstyled|depth|inlineStyleRanges|entityRanges|data|7jmi6|#leftNavSection,

<p>You can use this one also</p>

<pre><code>#leftNavSection,
#rightNavSection
        {
            display: inline-block;
        }

<p>I’m having trouble getting one of my DIVs to vertically align to the top of what will become a navigation section.  I have this style defined …</p>

<pre><code>#navbar {
    width: 100%; 
    font-family: Arial; 
    vertical-align: top; 
}
</code></pre>

<p>Here is the HTML behind my nav bar …</p>

<pre><code>&lt;div id="navbar"&gt;
    &lt;div id="leftNavSection"&gt;
    &lt;img alt="Logo" width="300" src="/assets/main_logo-791a416e4f99d38a339debb8dcebd7361d4172919425ace42ba2ce90336218e2.png"&gt;        
    &lt;/div&gt;
    &lt;div id="rightNavSection"&gt;
    Logged in as M. Bison 
    &lt;a href="/users/edit"&gt;Edit&lt;/a&gt;
    &lt;a rel="nofollow" data-method="delete" href="/logout"&gt;Log Out&lt;/a&gt;
    &lt;/div&gt;
&lt;/div&gt;
</code></pre>

<p>But as you can see from my Fiddle — <a href="https://jsfiddle.net/msynjppa/" rel="nofollow">https://jsfiddle.net/msynjppa/</a> , the right section is not vertically aligning to the top.  Any help is appreciated,</p>


How do I get my DIVs to vertically align to the top?
