You can t  Css today simply doesn t allow that   The logical rendering model is this one       If the object is a container element  then the effect is as if the contents of the container element were blended against the current background using a mask where the value of each pixel of the mask is     Reference   css transparency  The solution is to use a different element composition  usually using fixed or computed positions for what is today defined as a child   it may appear logically and visualy for the user as a child but the element doesn t need to be really a child in your code   A solution using css   fiddle   parent       width 500px      height 200px          background-image url  http   canop org blog wp-content uploads 2011 11 cropped-bandeau-cr C3 AAte-011 jpg        opacity  0 2     child       position  fixed      top 0      Another solution with javascript   fiddle

As mentioned by Tom  background-color  rgba 229 229 229  0 85  can do the trick  Place that on the style of the parent element and child wont be affected

You can t do that  unless you take the child out of the parent and place it via positioning   The only way I know and it actually works  is to use a translucid image   png with transparency  for the parent s background  The only disavantage is that you can t control the opacity via CSS  other than that it works

May be it s good if you define your background-image in the  after pseudo class  Write like this    parent      width 300px      height 300px      position relative      border 1px solid red     parent after      content         background url  http   www dummyimage com 300x300 000 fff amp text parent image        width 300px      height 300px      position absolute      top 0      left 0      opacity 0 5     child      background yellow      position relative      z-index 1      Check this fiddle
