 * I’m italian, and I apologize for my English.
    I use the theme aurelia, and i 
   want to use the filter to make clear the sidebar. I used: `filter: alpha(opacity
   =80);` there:
 *     ```
       #sidebar {
       	background-color:#000000;
       	font: 1em 'Lucida Grande', Verdana, Arial, Sans-Serif;
       	}
       ```
   
 * but it doesn’t work, the opacity is always 100 even if i’m going to 0.
    Can you
   help me? Thank you

 * Thank you, it works, but it hides also the words.
    I used this:
 *     ```
       background: rgb(0, 0, 0);
       5.background: rgba(0, 0, 0, 0.6);
       ```
   
 * and it works, but the widget are also with a black background. I search their
   class or id in the style.css but they aren’t there. Solutions?
    Thank you for
   the help 🙂

 * CSS opacity applied to a parent element means the children elements will inherit
   that opacity style.
    Try using a background image of the opacity you want instead.
 * These sorts of CSS-specific queries should really be asked on CSS forums such
   as [http://csscreator.com/forum](http://csscreator.com/forum) . It’s beyond WordPress.

 * So you advice to remove the background color and replace it with a transparent
   black image already?
