Change colour of div, that contains label + input, when checkbox is not :checked - without JS? : <p>First of all, thanks for reading. I'm not english-native speaking, but I will try to express clearly.</p>

<p>I have three ckeckboxes in a form, every checkbox with their label inside a div. The last of them is :required, when not :checked it's possible to change background of div without using JS? Only CSS, and without having to use Pure or Bootstrap.</p>

<pre><code>&lt;form&gt;
  &lt;div class="checkbox"&gt;
    &lt;input id="com1" type="checkbox" required&gt;
    &lt;label for="com1"&gt;Bla Bla (...)&lt;/label&gt;
  &lt;/div&gt;  

  &lt;button type="submit"&gt;SEND&lt;/button&gt;
&lt;/form&gt;
</code></pre>
