title: How to make an image resize to the screens height with CSS?
body: <p>Unlike many people who want an image to fill out the whole screen, I only care about the image height. How can I use CSS (preferably not JavasScript) to make an image with any size, fill up to 100% of the maximum possible browser window <strong>height</strong> while keeping aspect ratio of the image, the re-sized width of the image in respect to the browser does not matter. </p>
  
  <p>I'm working with this html:   </p>
  
  <pre><code>&lt;div class="images"&gt;
    &lt;img/&gt;
  &lt;/div&gt;
  </code></pre>
  
  <p>Thank you so much!</p>
