Can I set background image and opacity in the same property?
241
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);

Two methods:
- Convert to PNG and make the original image 0.2 opacity
- (Better method) have a
<div>that isposition: absolute;before#mainand the same height as#main, then apply the background-image andopacity: 0.2; filter: alpha(opacity=20);.

Yeah, the big problem with a PNG is the size. It is likely going to be really large. Now that we can specifyopacity: ...in all browsers, it way better!

You'd be surprised what you can squeeze out of PNG. For instance, at 0.2 opacity, you're probably not going to be picking out many details, so you can convert to Indexed-PNG. I actually use this on my own website, and it squashes a 1920x1080 background image to just under 250kb in size.

You better add z-index: -1 to that position:absolute, in order to allow using bottoms above the overlay. Good answer.

I added a "z-index: -1" to the CSS. That way the background image is affected by the opacity, not the rest of the contents of #main

I use:beforeinstead of:afterand then I don't have to tamper with thez-indexbecause:beforeends up below the main contents automatically. (Currently tested in Chrome and FF.)

@KajMagnus If you do that, then everything after that doesn't get shown. Try having an opacity of 1.0, and you'll see what I mean.

If you are getting a repeated background image, you may want/need to addbackground-repeat: no-repeat; background-attachment: fixed; background-position: center;within #main:after ....

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");

This will only work if the background is a solid color, if you have PNG24 which is a background and you want it to have opacity (on hover for example) then this will not work, and you will have to use the pseudo-element method, which is actually better since it could be used in IE 8 and up.

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);

You can also use RGBA 255,255,255 background-image: linear-gradient(to bottom, rgba(255,255,255,0.6) 0%,rgba(255,255,255,0.6) 100%), url(IMAGE_URL);

Sep 11 '16 at 15:22
@Roman You may set the rgba color component to the value used as background-color in the element or its embedding parent (tested on Chrome 58.0.3029.81, Edge 38.14393.0.0).

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;

You can use CSS psuedo selector ::after to achieve this. Here is a working demo.
.bg-container
width: 100%;
height: 300px;
border: 1px solid #000;
position: relative;
.bg-container .content
position: absolute;
z-index:999;
text-align: center;
width: 100%;
.bg-container::after
content: "";
position: absolute;
top: 0px;
left: 0px;
width: 100%;
height: 100%;
z-index:99;
background-image: url(https://i.stack.imgur.com/Hp53k.jpg);
background-size: cover;
opacity: 0.4;
<div class="bg-container">
<div class="content">
<h1>Background Opacity 0.4</h1>
</div>

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;

In your CSS add...
filter: opacity(50%);
In JavaScript use...
element.style.filter='opacity(50%)';
NB: Add vendor prefixes as required but Chromium should be fine without.

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.
HTML
background: url('http://www.earthtimes.org/newsimage/eat-lead-by-example-obesity-expert-tells-parents_139.jpg');
width: 100%;
height: 100%;
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.
HTML
background: url('http://www.earthtimes.org/newsimage/eat-lead-by-example-obesity-expert-tells-parents_139.jpg');
width: 100%;
height: 100%;
position: relative;
body
width: 100%;
min-height: 100%;
position: absolute;
top: 0;
left: 0;
margin: 0;
background: rgba(255, 255, 255, .75);

Tip: notice how the HTML isposition: relative, while the body isposition: 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.

Tip: RGBA corresponds to RedGreenBlueAlpha. So, the browser interpretsrgba(0,255,0,.75)as something exemplified byred:0, green:255, blue:0, alpha:'75%'.
*A full compatibility table can be found at Can I Use. However, please also note that you need to click the "Show All" to see that IE9 supports it.
Addendum
Since I have already answered the question but I have more I want to add, I am titling this section addendum and having it add some potentially helpful information. So, to extrapolate even further on the content above, you could use an SVG as a background image to do wicked awesome things. For example, you could create a loading screen background featuring a cool website icon as you can see in the example of a base64 encoded SVG below.

Tip: Thebackground-size: coverCSS causes the SVG logo in the background to be resized to the size of the HTML element.

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.

This is not correct, there is a CSS3 declaration:opactiy: 1;, not just RGBa.

What he is saying is setting thebackground-imagestyle on a container and then setting anopacitystyle on the same element. That would also make the text and other contents of that element transparent. Try this out if you don't believe me: w3schools.com/Css/tryit.asp?filename=trycss_transparency

I just added position=absolute,top=0,width=100% in the #main and set the opacity value to the #background
#mainheight:100%;position:absolute; top:0;width:100%
#background//same height as main;background-image:url(image URL);opacity:0.2
I applied the background to a div before the main.

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.

ArtB got it right w/ the last note. This is a perfectly fine solution for another problem. There are times when this isn't the right solution and this is one of them.

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 & browsers

Two methods:
- Convert to PNG and make the original image 0.2 opacity
- (Better method) have a
<div>that isposition: absolute;before#mainand the same height as#main, then apply the background-image andopacity: 0.2; filter: alpha(opacity=20);.

Yeah, the big problem with a PNG is the size. It is likely going to be really large. Now that we can specifyopacity: ...in all browsers, it way better!

You'd be surprised what you can squeeze out of PNG. For instance, at 0.2 opacity, you're probably not going to be picking out many details, so you can convert to Indexed-PNG. I actually use this on my own website, and it squashes a 1920x1080 background image to just under 250kb in size.

You better add z-index: -1 to that position:absolute, in order to allow using bottoms above the overlay. Good answer.

I added a "z-index: -1" to the CSS. That way the background image is affected by the opacity, not the rest of the contents of #main

I use:beforeinstead of:afterand then I don't have to tamper with thez-indexbecause:beforeends up below the main contents automatically. (Currently tested in Chrome and FF.)

@KajMagnus If you do that, then everything after that doesn't get shown. Try having an opacity of 1.0, and you'll see what I mean.

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");

This will only work if the background is a solid color, if you have PNG24 which is a background and you want it to have opacity (on hover for example) then this will not work, and you will have to use the pseudo-element method, which is actually better since it could be used in IE 8 and up.

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);

@Roman You may set the rgba color component to the value used as background-color in the element or its embedding parent (tested on Chrome 58.0.3029.81, Edge 38.14393.0.0).

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;

You can use CSS psuedo selector ::after to achieve this. Here is a working demo.
.bg-container

border: 1px solid #000;
position: relative;
.bg-container .content
position: absolute;
z-index:999;

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

.granddata:after

In your CSS add...
filter: opacity(50%);
In JavaScript use...
element.style.filter='opacity(50%)';
NB: Add vendor prefixes as required but Chromium should be fine without.

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.
HTML
background: url('http://www.earthtimes.org/newsimage/eat-lead-by-example-obesity-expert-tells-parents_139.jpg');
width: 100%;
height: 100%;
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.
HTML
background: url('http://www.earthtimes.org/newsimage/eat-lead-by-example-obesity-expert-tells-parents_139.jpg');
width: 100%;
height: 100%;
position: relative;
body
width: 100%;
min-height: 100%;
position: absolute;
top: 0;
left: 0;
margin: 0;
background: rgba(255, 255, 255, .75);
<p>Lorem ipsum dolor sit amet, et id, maecenas a convallis, elit facilisi congue augue id ac. Suscipit luctus egestas rutrum, amet tincidunt porttitor ante convallis magna, vivamus amet at turpis, ante lacinia blandit vel metus mauris rutrum. Ipsum nam adipiscing.

Tip: notice how the HTML isposition: relative, while the body isposition: 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.

Tip: RGBA corresponds to RedGreenBlueAlpha. So, the browser interpretsrgba(0,255,0,.75)as something exemplified byred:0, green:255, blue:0, alpha:'75%'.
*A full compatibility table can be found at Can I Use. However, please also note that you need to click the "Show All" to see that IE9 supports it.
Addendum
Since I have already answered the question but I have more I want to add, I am titling this section addendum and having it add some potentially helpful information. So, to extrapolate even further on the content above, you could use an SVG as a background image to do wicked awesome things. For example, you could create a loading screen background featuring a cool website icon as you can see in the example of a base64 encoded SVG below.

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.
HTML
background: url('http://www.earthtimes.org/newsimage/eat-lead-by-example-obesity-expert-tells-parents_139.jpg');
width: 100%;
height: 100%;
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.
HTML
background: url('http://www.earthtimes.org/newsimage/eat-lead-by-example-obesity-expert-tells-parents_139.jpg');

body

min-height: 100%;

Tip: notice how the HTML isposition: relative, while the body isposition: 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.

Tip: RGBA corresponds to RedGreenBlueAlpha. So, the browser interpretsrgba(0,255,0,.75)as something exemplified byred:0, green:255, blue:0, alpha:'75%'.

Addendum
Since I have already answered the question but I have more I want to add, I am titling this section addendum and having it add some potentially helpful information. So, to extrapolate even further on the content above, you could use an SVG as a background image to do wicked awesome things. For example, you could create a loading screen background featuring a cool website icon as you can see in the example of a base64 encoded SVG below.

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.
HTML
background: url('http://www.earthtimes.org/newsimage/eat-lead-by-example-obesity-expert-tells-parents_139.jpg');

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.

Tip: notice how the HTML isposition: relative, while the body isposition: 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.

Tip: RGBA corresponds to RedGreenBlueAlpha. So, the browser interpretsrgba(0,255,0,.75)as something exemplified byred:0, green:255, blue:0, alpha:'75%'.
*A full compatibility table can be found at Can I Use. However, please also note that you need to click the "Show All" to see that IE9 supports it.
Addendum
Since I have already answered the question but I have more I want to add, I am titling this section addendum and having it add some potentially helpful information. So, to extrapolate even further on the content above, you could use an SVG as a background image to do wicked awesome things. For example, you could create a loading screen background featuring a cool website icon as you can see in the example of a base64 encoded SVG below.

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.

This is not correct, there is a CSS3 declaration:opactiy: 1;, not just RGBa.

What he is saying is setting thebackground-imagestyle on a container and then setting anopacitystyle on the same element. That would also make the text and other contents of that element transparent. Try this out if you don't believe me: w3schools.com/Css/tryit.asp?filename=trycss_transparency

I just added position=absolute,top=0,width=100% in the #main and set the opacity value to the #background
#mainheight:100%;position:absolute; top:0;width:100%
#background//same height as main;background-image:url(image URL);opacity:0.2
I applied the background to a div before the main.

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.

ArtB got it right w/ the last note. This is a perfectly fine solution for another problem. There are times when this isn't the right solution and this is one of them.
