hello i wanted to know how can i transparent those (in red) bars and i'm curious how to transparent the white boars to 50%, I use phpBB2 virsion 
(i have already transparent the background as you see)

and this is my forum link: www.theworldofdarkness.forumne.com

Look for this in your CSS Stylesheet:

Code:

th {
    background-color: #069;
    background-image: url("http://2img.net/i/fa/subsilver/back_title.gif");
    color: #FFA34F;
    font-size: 11px;
    font-weight: 700;
    height: 25px;
    padding: 2px 3px;
}

Remove the background image and change the background color to make it transparent.

@SLGray sorry, it is not what i wanted. i want the background i've picked and transparent the bars and the boards

Hi @DarknessGirl,

For a background image, the best solution would be to use the opacity property. Here's the CSS :

Code:

th, .catHead, .catBottom { opacity:0.5 }

Note however, this will also affect the text transparency. If you want only the background to be transparent, I'd recommend editing your background image with a photo editor and adjusting the opacity to what pleases you.
