this question has answer here:

simple may need create background website container semi-transparent. if add opacity: 0.5; inside of #content end having entire container, widgets , letters going ghost. should apply transparency background image? 1 answer add transparency picture inside of ps still curious.

#content .container {     background:url(images/menu_bar.png) left top repeat-y !important; }

give try:

#content .container {   width: 500px;   height: 100px;   background: url(../images/menu_bar.png) left top repeat-y rgba(0, 0, 0, 0.5) !important; }
