targeting css class under element with id
<p>My html page structure is like this</p>

<pre><code>&lt;div id="myPage"&gt;
   &lt;div class="input-group bootstrap-touchspin"&gt;
       &lt;input id="784069" class="form-control my-class touchspin" type="text" value="0" name="784069" default-field="True" style="display: block;"&gt;
   &lt;/div&gt;
&lt;/div&gt;
</code></pre>

<p>I tried to fetch this element with css like this</p>

<pre><code>#myPage .input-group .bootstrap-touchspin {
}
</code></pre>
