title: How do you fill the horizontal space in a line of flex children?
body: <p><div class="snippet" data-lang="js" data-hide="false" data-console="false" data-babel="false">
  <div class="snippet-code">
  <pre class="snippet-code-css lang-css prettyprint-override"><code>.flex {
      flex-direction: row;
      flex-wrap: nowrap;
      justify-content: space-around;
  } </code></pre>
  <pre class="snippet-code-html lang-html prettyprint-override"><code>&lt;div class="flex"&gt;
    &lt;div class="child"&gt;
      &lt;svg&gt;&lt;/svg&gt;1
    &lt;/div&gt;
    &lt;div class="child"&gt;
      &lt;svg&gt;&lt;/svg&gt;2
    &lt;/div&gt;
    &lt;div class="child"&gt;
      &lt;svg&gt;&lt;/svg&gt;3
    &lt;/div&gt;
  &lt;/div&gt;</code></pre>
  </div>
  </div>
  </p>
  <p>Currently the width of the child divs is determined by the size of the svg. I would like them to take up all available room in the row, so that there are three divs each taking 33% width. Can I do this with flexbox?</p>
