flex Css doesn't support in Safari , iPhone 5 and mobile Browser Webviews
<p>Those are HTML:</p>

<pre><code>&lt;div class="btn-toolbar text-center" role="toolbar"&gt;
      &lt;a href="#" class="btn btn-success"&gt;Link 1&lt;/a&gt;
      &lt;a href="#" class="btn btn-success"&gt;Link 11&lt;/a&gt;
      &lt;a href="#" class="btn btn-success"&gt;Link 111&lt;/a&gt;
      &lt;a href="#" class="btn btn-success"&gt;Link 1111&lt;/a&gt;
      &lt;a href="#" class="btn btn-success"&gt;Link 11111&lt;/a&gt;
      &lt;a href="#" class="btn btn-success"&gt;Link 111111&lt;/a&gt;
      &lt;a href="#" class="btn btn-success"&gt;Link 11111&lt;/a&gt;
      &lt;a href="#" class="btn btn-success"&gt;Link 1111&lt;/a&gt;
      &lt;a href="#" class="btn btn-success"&gt;Link 111&lt;/a&gt;
      &lt;a href="#" class="btn btn-success"&gt;Link 111&lt;/a&gt;
      &lt;a href="#" class="btn btn-success"&gt;Link 11&lt;/a&gt;
      &lt;a href="#" class="btn btn-success"&gt;Link 111&lt;/a&gt;
      &lt;a href="#" class="btn btn-success"&gt;Link 1111111&lt;/a&gt;
      &lt;a href="#" class="btn btn-success"&gt;Link 111111111&lt;/a&gt;
      &lt;a href="#" class="btn btn-success"&gt;Link 111&lt;/a&gt;
      &lt;a href="#" class="btn btn-success"&gt;Link 11111&lt;/a&gt;
      &lt;a href="#" class="btn btn-success"&gt;Link 11&lt;/a&gt;
      &lt;a href="#" class="btn btn-success"&gt;Link 11111111111&lt;/a&gt;
      &lt;a href="#" class="btn btn-success"&gt;Link 11111&lt;/a&gt;
      &lt;a href="#" class="btn btn-success"&gt;Link 1&lt;/a&gt;
    &lt;/div&gt;

<p>Those are CSS:</p>

<pre><code>.btn-toolbar{
    display: -webkit-box;
    display: -webkit-flex;
    display: -moz-box;
    display: -ms-flexbox;
    display: flex;
  -webkit-flex-wrap: wrap;
      -ms-flex-wrap: wrap;
          flex-wrap: wrap;
}
.btn-toolbar .btn{
  -webkit-box-flex: 1;
  -moz-box-flex: 1;
  -webkit-flex: 1;
      -ms-flex: 1;
          flex: 1;
}
</code></pre>

<p>flex Css doesn't support in Safari , iPhone 5, IOS 6  and mobile Browser Webviews. I use browser support but it's still not working. Any kind of solution please. I don't want to use any fixed width.</p>
