title: CSS Can't move my images
body: <p>I'm trying to move some images but I can't move them. I moved other images just fine but these ones won't move?</p>
  
  <p><strong>HTML</strong>: (it's a little larger with more images but i can't even move one)</p>
  
  <pre><code>&lt;main&gt; 
    &lt;p class="window1"&gt; Window 1 &lt;/p&gt;
    &lt;img class="uparrow1" src="images/up.png" alt="Up"&gt;
  &lt;/main&gt;
  </code></pre>
  
  <p><strong>CSS:</strong> </p>
  
  <pre><code>.uparrow1 {
    position: absolute;
    top: 300px;
    left: 100px;
  }
  </code></pre>
  
  <p>It doesn't response at any command. </p>
