title: How to in Jssor full width + height by window size
body: <p>I would like to have fixed height by window height + full width.
  For example picture of size 2600x1800.
  Window size is 950x450.</p>
  <p>I call <code>ScaleSlider()</code> function and inside:</p>
  <ol>
  <li><p>When I use <code>$ScaleWidth(width)</code> height is 1800.</p>
  </li>
  <li><p>When I use <code>$ScaleHeight(height)</code> then height is OK, but width is scaled to cca 800.</p>
  </li>
  </ol>
  <p>I used config param $FillMode: from 0 to 5, but not expected result.</p>
  <p>I don't need aspect ratio or scale. For me is ok, that height of image will be like cutted.</p>
  <p>It works as expected when I harcoded IMG tag with: <code>object-fit: cover;width: 100%;height: 100%;</code> and then up to everything to 100%, then parent class slider_container set to <code>transform: scale(1); height: 450px</code>. After resize browser everything is broken again.</p>
  <p>How to do it with jssor please?</p>
