How resize filed input datetime in bootstrap-datetimepicker?
<p>I decided to change dashboard selected period rage datetime.
I chose bootstrap-datetimepicker.</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-js lang-js prettyprint-override"><code>$(function () {              
                $("#datetime_input").datetimepicker({
                    locale: 'ru'
                });
                $("#datetime_output").datetimepicker({
                    locale: 'ru'
                });
   });</code></pre>
<pre class="snippet-code-html lang-html prettyprint-override"><code>&lt;div class="row"&gt;
        &lt;span&gt;C&lt;/span&gt;
        &lt;div class='col-xs-3'&gt;
            &lt;div class="form-group"&gt;
                &lt;div class='input-group date' id='datetime_input'&gt;
                    &lt;input id="INPUT_DATETIME" type='text' class="form-control" value="${INPUT_DATETIME}"/&gt;
                    &lt;span class="input-group-addon"&gt;
                        &lt;span class="glyphicon glyphicon-calendar"&gt;&lt;/span&gt;
                    &lt;/span&gt;
                &lt;/div&gt;
            &lt;/div&gt;
        &lt;/div&gt;

        &lt;span&gt;По&lt;/span&gt;
        &lt;div class='col-sm-3'&gt;
            &lt;div class="form-group"&gt;
                &lt;div class='input-group date' id='datetime_output'&gt;
                    &lt;input id="OUTPUT_DATETIME" type='text' class="form-control" value="${OUTPUT_DATETIME}"/&gt;
                    &lt;span class="input-group-addon"&gt;
                        &lt;span class="glyphicon glyphicon-calendar"&gt;&lt;/span&gt;
                    &lt;/span&gt;
                &lt;/div&gt;
            &lt;/div&gt;
        &lt;/div&gt;
&lt;/div&gt;</code></pre>
</div>
