Set opacity of background image without affecting child elements

Question

Is it possible to set the opacity of a background image without affecting the opacity of child elements   Example  All links in the footer need a custom bullet  background image  and the opacity of the custom bullet should be 50    HTML   lt div id  footer  gt       lt ul gt           lt li gt  lt a href     gt Link 1 lt  a gt  lt  li gt           lt li gt  lt a href     gt Link 2 lt  a gt  lt  li gt           lt li gt  lt a href     gt Link 3 lt  a gt  lt  li gt           lt li gt  lt a href     gt Link 4 lt  a gt  lt  li gt           lt li gt  lt a href     gt Link 5 lt  a gt  lt  li gt       lt  ul gt   lt  div gt      CSS   footer ul li       background  url  images arrow png  no-repeat 0 50         What I ve Tried  I tried setting the opacity of the list items to 50   but then the opacity of the link text is also 50  - and there doesn t seem to be a way to reset the opacity of child elements    footer ul li       background  url  images arrow png  no-repeat 0 50          will also set the opacity of the link text                opacity  0 5      I also tried using rgba  but that doesn t have any effect on the background image    footer ul li          rgba doesn t apply to the background image        background  rgba 255  255  255  0 5  url  images arrow png  no-repeat 0 50

Another option is CSS Tricks approach of inserting a pseudo element the exact size of the original element right behind it to fake the opaque background effect that we re looking for  Sometimes you will need to set a height for the pseudo element   div     width  200px    height  200px    display  block    position  relative     div  after     content        background  url image jpg     opacity  0 5    top  0    left  0    bottom  0    right  0    position  absolute    z-index  -1

To really fine-tune things  I recommend placing the appropriate selections in browser-targeting wrappers  This was the only thing that worked for me when I could not get IE7 and IE8 to  play nicely with others   as I am currently working for a software company who continues to support them       color or background image for all browsers  of course                 myBackground       background-color  666        target chrome  amp  safari without disrupting IE7-8     media screen and  -webkit-min-device-pixel-ratio 0         myBackground           -khtml-opacity  50           opacity  50             target firefox without disrupting IE     -moz-document url-prefix          myBackground           -moz-opacity  50          opacity 0 5             and IE last so it doesn t blow up     myBackground       opacity  50      filter alpha opacity 50       filter  progid DXImageTransform Microsoft Alpha opacity 0 5       I may have redundancies in the above code -- if anyone wishes to clean it up further  feel free

This will work with every browser  div    -khtml-opacity  50    -moz-opacity  50    -ms-filter  alpha opacity 50      filter alpha opacity 50     filter  progid DXImageTransform Microsoft Alpha opacity 0 5     opacity  50       If you don t want transparency to affect the entire container and its children  check this workaround  You must have an absolutely positioned child with a relatively positioned parent     Check demo at http   www impressivewebs com css-opacity-that-doesnt-affect-child-elements

Just to add to the above  you can use the alpha channel with the new color attributes eg  rgba 0 0 0 0  ok so this is black but with zero opacity so as a parent it will not affect the child  This only works on Chrome  FF  Safari and    I thin O   convert your hex colours to RGBA

The  filter  property  needs an integer for percentage of opacity instead of double  in order to work for IE7 8   filter  progid DXImageTransform Microsoft Alpha opacity 50     P S   I post this as an answer  since SO  needs at least 6 changed characters for an edit

User · Answer

we can figure out that by not playing with opacity just by using rgba color e g  quot background-color  rgba 0 0 0  0 5  quot  Sample    Previous Css    login-card             others CSS   background-color   121e1b    opacity  0 5     To     login-card                 others CSS       background-color  rgba 0  0  0  0 5

If you have to set the opacity only to the bullet  why don t you set the alpha channel directly into the image  By the way I don t think there is a way to set the opacity to a background image via css without changing the opacity of the whole element  and its children too

I found a pretty good and simple tutorial about this issue  I think it works great  and though it supports IE  I just tell my clients to use other browsers    CSS background transparency without affecting child elements  through RGBa and filters  From there you can add gradient support  etc

You can use CSS linear-gradient   with rgba      x000D   x000D  div   x000D    width  300px  x000D    height  200px  x000D    background  linear-gradient rgba 255 255 255  5   rgba 255 255 255  5    url  https   i imgur com xnh5x47 jpg    x000D    x000D  span   x000D    background  black  x000D    color  white  x000D    x000D   lt div gt  lt span gt Hello world  lt  span gt  lt  div gt  x000D   x000D   x000D

Unfortunately  at the time of writing this answer  there is no direct way to do this  You need to    use a semi-transparent image for background  much easier   add an extra element  like div  next to children which you want the opaque  add background to it and after making it semi-transparent  position it behind mentioned children

User · Answer

Take your image into an image editor  turn down the opacity  save it as a  png and use that instead

If you are using the image as a bullet  you might consider the  before pseudo element    footer ul li       footer ul li before       content  url  images arrow png       filter alpha opacity 50       filter  progid DXImageTransform Microsoft Alpha opacity 0 5       opacity  50
