Can I set background image and opacity in the same property

Question

I can see in CSS references how to set image transparency and how to set a background image  But how can I combine these two in order to set a transparent background image   I have an image that I d like to use as a background  but it is too bright - I d like to turn the opacity down to about 0 2  How can I do this    main       background-image  url  wp-content uploads 2010 11 tandem jpg

You can use CSS psuedo selector   after to achieve this  Here is a working demo      x000D   x000D   bg-container  x000D    width  100   x000D    height  300px  x000D    border  1px solid  000  x000D    position  relative  x000D    x000D   bg-container  content  x000D    position  absolute  x000D    z-index 999  x000D    text-align  center  x000D    width  100   x000D    x000D   bg-container  after  x000D    content      x000D    position  absolute  x000D    top  0px  x000D    left  0px  x000D    width  100   x000D    height  100   x000D    z-index -99  x000D    background-image  url https   i stack imgur com Hp53k jpg   x000D    background-size  cover  x000D    opacity  0 4  x000D    x000D   lt div class  bg-container  gt  x000D      lt div class  content  gt  x000D        lt h1 gt Background Opacity 0 4 lt  h1 gt  x000D      lt  div gt  x000D   lt  div gt  x000D   x000D   x000D

Simple solution  if you need to set the gradient to background-image only   background-image  url IMAGE URL      fallback for older browsers     background-image  linear-gradient to bottom  rgba 0 0 0 0 6  0  rgba 0 0 0 0 6  100    url IMAGE URL

Two methods      Convert to PNG and make the original image 0 2 opacity    Better method  have a  lt div gt  that is position  absolute  before  main and the same height as  main  then apply the background-image and opacity  0 2  filter  alpha opacity 20

I had a similar issue and I just took the background image with photoshop and created a new  png with the opacity I needed  Problem solved without worrying about if my CSS worked accross all devices  amp  browsers

Solution with 1 div and NO transparent image   You can use the multibackground CSS3 feature and put two backgrounds  one with the image  another with a transparent panel over it  cause I think there s no way to set directly the opacity of the background image    background  -moz-linear-gradient top  rgba 0  0  0  0 7  0   rgba 0  0  0  0 7  100    url bg png  repeat 0 0  url https   cdn sstatic net stackoverflow img apple-touch-icon png  repeat 0 0   background  -moz-linear-gradient top  rgba 255 255 255 0 7  0   rgba 255 255 255 0 7  100    url https   cdn sstatic net stackoverflow img apple-touch-icon png  repeat 0 0   background  -webkit-gradient linear  left top  left bottom  color-stop 0  rgba 255 255 255 0 7    color-stop 100  rgba 255 255 255 0 7     url https   cdn sstatic net stackoverflow img apple-touch-icon png  repeat 0 0   background  -webkit-linear-gradient top  rgba 255 255 255 0 7  0  rgba 255 255 255 0 7  100    url https   cdn sstatic net stackoverflow img apple-touch-icon png  repeat 0 0   background  -o-linear-gradient top  rgba 255 255 255 0 7  0  rgba 255 255 255 0 7  100    url https   cdn sstatic net stackoverflow img apple-touch-icon png  repeat 0 0   background  -ms-linear-gradient top  rgba 255 255 255 0 7  0  rgba 255 255 255 0 7  100    url https   cdn sstatic net stackoverflow img apple-touch-icon png  repeat 0 0   background  linear-gradient to bottom  rgba 255 255 255 0 7  0  rgba 255 255 255 0 7  100    url https   cdn sstatic net stackoverflow img apple-touch-icon png  repeat 0 0    You can t use rgba 255 255 255 0 5  because alone it is only accepted on the back  so you I ve used generated gradients for each browser for this example  that s why it is so long   But the concept is the following   background  tranparentColor  url  myImage       http   jsfiddle net pBVsD 1

I saw this and in CSS3 you can now place code in like this  Lets say I want it to cover the whole background I would do something like this  Then with hsla 0 0  100  0 70  or rgba you use a white background with whatever percentage saturation or opacity to get the look you desire      body      background-attachment  fixed      background-image  url    images Store1 jpeg       display  block      position  absolute      left  0      top  0      width  100       height  100       z-index  1      background-color  hsla 0 0  100  0 70       background-blend-mode  overlay      background-repeat  no-repeat

Well the only CSS way of doing only background transparency is via RGBa but since you want to use an image I would suggest using Photoshop or Gimp to make the image transparent and then using it as the background

I have used the answer of  Dan Eastwell and it works very well  The code is similar to his code but with some additions    granddata       position  relative      margin-left  0 5       margin-right  0 5      granddata after       content           display  block      position  absolute      top  0      left  0      background-image  url   Images blabla jpg        width  100       height  100       opacity  0 2      z-index  -1      background-repeat  no-repeat      background-position  center      background-attachment fixed

A great way to do it for a simple image is to do it using only CSS to set the background of the HTML element like so    x000D   x000D  HTML   x000D      background  url  http   www earthtimes org newsimage eat-lead-by-example-obesity-expert-tells-parents 139 jpg    x000D      width  100   x000D      height  100   x000D    x000D   x000D   x000D    If you want to get fancy  and set its opacity  then  in IE9    you can set a transparent background color of the body  This works by overlaying semitransparent white to make the image whiter  and appear to be brighter  For example  white with 75  opacity  rgba 255 255 255  75   would produce the following effect    x000D   x000D  HTML   x000D    background  url  http   www earthtimes org newsimage

x000D     Tip  notice how  the HTML is position  relative  while the body is position  absolute  This is to prevent the background color of the body from behaving more like a highlighter of the text in the body    This could even be expanded to something comparable to  but still very distinct from  CSS filters by changing around the body s RGBA color background  For example  rgba 0 255 0  75  would create a very green tint as you can see in the code snippet    x000D   x000D  HTML   x000D      background  url  http   www earthtimes org newsimage

I came across this post as I had the same issue then I thought why mess about with css  adjusting values and hitting refresh when you can easily adjust the opacity in Photoshop  Copy the image  paste it as a new layer then move the opacity slider

[css] Can I set background image and opacity in the same property?
