title: Set height on all images in list with specific class
body: <p>I need to ask, how to set height on all images which are on specific list and class. </p>
  
  <p>I have HTML:</p>
  
  <pre><code>&lt;li class="product-category product first"&gt;
  &lt;a href="#"&gt;&lt;img src="url-to-image"&gt;&lt;/a&gt;&lt;/li&gt;   
  </code></pre>
  
  <p>And I tried to do it with this code sample, but without working:</p>
  
  <pre><code>li.product-category product&gt;img {
  </code></pre>
  
  <p>height: 10px !important;
  }</p>
  
  <p>Where is the problem? How to change CSS to work it properly? I need to change height on all images with class <strong>product-category</strong>.</p>
  
  <p>Thank you for help, I think, it will be small improvement, but I do not know, which.</p>
  
  <p>Have a nice day!</p>
