title: Bootstrap 4 issue with keeping cols in a row on iphone
body: <p>I am a bit puzzled. How can I get this timer here to stay in 1 line on iPhone? On iPhone the "seconds" goes to the next line and looks pretty bad => <a href="https://ibb.co/k2iCfo" rel="nofollow noreferrer">https://ibb.co/k2iCfo</a></p>
  
  <p>Bootstrap 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-html lang-html prettyprint-override"><code>&lt;div class="container text-center"&gt;
    &lt;div class="row text-center"&gt;
      &lt;div id = "timer_frame" class="col-md-12"&gt; 
        &lt;div class="row justify-content-md-center d-flex"&gt;
          &lt;div class="col text-center col_bg"&gt;
            &lt;span class="days display-4 timer_font_color"&gt;&lt;/span&gt;
            &lt;span class="d-block timer_font_color"&gt;Days&lt;/span&gt;
          &lt;/div&gt;
  
          &lt;div class="col text-center timer_font_color col_bg"&gt;
            &lt;span class="hours display-4 timer_font_color"&gt;&lt;/span&gt;
            &lt;span class="d-block timer_font_color"&gt;Hours&lt;/span&gt;
          &lt;/div&gt;
          
          &lt;div class="col text-center timer_font_color col_bg"&gt;
            &lt;span class="minutes display-4"&gt;&lt;/span&gt;
            &lt;span class="d-block timer_font_color"&gt;Minutes&lt;/span&gt;
          &lt;/div&gt;
  
          &lt;div class="col text-center timer_font_color col_bg"&gt;
            &lt;span class="seconds display-4"&gt;&lt;/span&gt;
            &lt;span class="d-block timer_font_color"&gt;Seconds&lt;/span&gt;
          &lt;/div&gt;
        &lt;/div&gt;
      &lt;/div&gt;
    &lt;/div&gt;
  &lt;/div&gt;</code></pre>
