title: After opening modal the sidebar gets "cut". How to make the height of the sidebar responsive?
body: <p>After opening the modal my sidebar looks like that:</p>
  
  <p><a href="https://i.stack.imgur.com/fUBjh.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/fUBjh.png" alt="enter image description here"></a></p>
  
  <p>I wonder what can I do about that? 
  Modals are located outside the body tag (cause I blur all the stuff located in div named "blur-container2"). So all things except of modals are located in "blur-container2".</p>
  
  <p>The simplified structure looks like that:</p>
  
  <pre><code>&lt;html&gt;
  &lt;body&gt;
  &lt;div class="blur-container2"&gt;&lt;/div&gt;
  &lt;/body&gt;
  //Modals are here//
  &lt;/html&gt;
  </code></pre>
  
  <p>My body and html css code: </p>
  
  <pre><code>body, html {
      height: 100%;
      color: black;
  }
  </code></pre>
  
  <p>The container where the sidebar located in: </p>
  
  <pre><code>.blur-container2 {
      background-image: url(http://southernhoopsreport.com/wp-content/uploads/2018/11/156689-download-white-gradient-background-2447x1468-1080p.jpg);
      background-repeat: no-repeat;
      background-attachment: fixed;
      background-size: cover!important;
      background-position: center;
      display: block;
      overflow: auto;
      height: 100%!important;
  }
  </code></pre>
  
  <p>Modal css:</p>
  
  <pre><code>.modal {
  
  
     border-radius: 17px;
      background-color: rgb(255, 255, 255)!important;
      backdrop-filter: blur(15px);
      color: rgb(0, 0, 0);
          overflow-y: auto;
      width: 55%;
      max-height: 70%;
      margin: auto;
      padding: 0;
      border-radius: 2px;
      background-color: #fafafa;
      will-change: top,opacity;
  }
  </code></pre>
  
  <p>Model overlay:</p>
  
  <pre><code>.modal, .modal-overlay {
      position: fixed;
      left: 0;
      display: none;
      right: 0;
  }
  </code></pre>
