title: How to apply disabled style of ASP.net dropdownlist
body: <p>Suppose that I have a dropdownlist in ASP.net like that:</p>
  
  <pre><code>&lt;asp:DropDownList ID="ddOwnershipDocumentType" class="msbdd" runat="server"&gt;
  &lt;/asp:DropDownList&gt;
  </code></pre>
  
  <p>Here is the definition of msdbdd:</p>
  
  <pre><code>.msbdd {
      font-family: WMitraBold;
      font-weight: normal;
      color: #000;
      font-size: 12px;
      text-align: right !important;
      direction: rtl;
      width: 100%;
      border: 1px solid #aaa;
      outline: none;
      box-sizing: border-box;
      background-color: rgba(255,255,255,0.7);
  }
  </code></pre>
  
  <p>I'm trying to apply style to this dropdownlist whenever its disabled. I tried <code>.msbdd select[disabled]</code>, <code>.msbdd select:disabled</code> , <code>.msbdd select[readonly]</code>, <code>.msbdd select:read-only</code> but none of them Worked (in Chrome).</p>
  
  <p>How can I achieve selecting a disabled dropdownlist in CSS?</p>
