title: How to align items to left (header)
body: <p>I'm trying to align some items to the left, but I don't know what I'm doing wrong. 
  I'm making the youtube header, and at this time, I've done this </p>
  
  <p><a href="https://i.stack.imgur.com/3WVup.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/3WVup.png" alt="enter image description here"></a></p>
  
  <p>I got to align the first two items to the right with a simple padding, but when it comes to the left side of the header, nothing works. I've used <em>align-items</em> but they do not move. </p>
  
  <p>this is my html code:</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>header {
    width: 100%;
    padding: 0px;
    /*FLEX*/
    display: flex;
    flex-direction: row;
    border-bottom: 1px solid #000;
  }
  
  header .youtube nav a span {
    color: red;
    padding: 5px;
    line-height: 50px;
  }
  
  header .menu nav a span {
    padding: 30px;
    line-height: 50px;
  }
  
  header .bloque nav a span {
    line-height: 50px;
    align-items: flex-end;
  }
  
  header .bloque nav img {
    line-height: 50px;
    align-items: flex-end;
    width: 50;
  }</code></pre>
  <pre class="snippet-code-html lang-html prettyprint-override"><code>&lt;header&gt;
    &lt;div class="menu"&gt;
  
      &lt;nav&gt;
        &lt;a href="#"&gt;&lt;span class="icon-menu"&gt;&lt;/span&gt;&lt;/a&gt;
      &lt;/nav&gt;
    &lt;/div&gt;
    &lt;div class="youtube"&gt;
      &lt;nav&gt;
        &lt;a href="#"&gt;&lt;span class="icon-youtube"&gt;&lt;/span&gt;YouTube&lt;/a&gt;
      &lt;/nav&gt;
    &lt;/div&gt;
    &lt;form&gt;
      &lt;fieldset&gt;
        &lt;input type="search" placeholder="Search"&gt;
        &lt;button type="submit"&gt;
         &lt;span class="icon-magnifying-glass"&gt;&lt;/span&gt;
        &lt;/button&gt;
      &lt;/fieldset&gt;
    &lt;/form&gt;
    &lt;div class="bloque"&gt;
      &lt;nav&gt;
        &lt;a href="#"&gt;&lt;span class="icon-camera"&gt;&lt;/span&gt;&lt;/a&gt;
        &lt;a href="#"&gt;&lt;span class="icon-grid"&gt;&lt;/span&gt;&lt;/a&gt;
        &lt;a href="#"&gt;&lt;span class="icon-forward"&gt;&lt;/span&gt;&lt;/a&gt;
        &lt;a href="#"&gt;&lt;span class="icon-globe"&gt;&lt;/span&gt;&lt;/a&gt;
        &lt;img src="guía.png" width="100"&gt;
      &lt;/nav&gt;
      &lt;div/&gt;
  &lt;/header&gt;</code></pre>
  </div>
  </div>
  </p>
  
  <p>when I use <em>justify-content:Space-round</em>, the items are placed the way I want to, but not properly spaced between them.  But for some strange reason when I use <em>align-item:flex-end</em> they are arranged like in the pic related. how do I solve this? any advice?</p>
