title: UIWebView's content background color not transparent
body: <p>I'm using an UIWebView to load some HTML text from a plist. </p>
  
  <p>I managed to make its background transparent using</p>
  
  <pre><code>webView.opaque = NO;
  webview.backgroundColor = [UIColor clearColor];
  </code></pre>
  
  <p>but the content, which is the text loaded from the plist, is shown with a disturbing white background. </p>
  
  <p>I'm loading it using </p>
  
  <pre><code>NSString *descr = [NSString stringWithFormat:@"&lt;html&gt;&lt;head&gt;&lt;style&gt; body{font-size:16; font-family: Helvetica; color: black;} strong{font-family: Arial; font-weight: bold; font-size:16} .bg{background:transparent;}&lt;/style&gt;&lt;/head&gt;&lt;body&gt;&lt;div class='bg'&gt;%@&lt;/div&gt;&lt;/body&gt;&lt;/html&gt;",[item valueForKey:@"description"]];
  [webView loadHTMLString:descr baseURL:nil];
  </code></pre>
  
  <p>I've tried setting the <code>.bg</code> class background color to <code>rgba(255,0,0,0.0)</code>, but nothing worked.</p>
  
  <p>Also tried setting <code>webView.scrollView.backgroundColor : [UIColor clearColor];</code></p>
  
  <p>Any advice on how to get the UIWebView's content background transparent?</p>
