I have a background image in the following div, but the image gets cut off:
<div style='text-align:center;background-image: url(/media/img_1_bg.jpg);background-repeat:no-repeat;width:450px;height:900px;' id="mainpage" align="center">
Is there a way to show the background image without cutting it off?
You can achieve this with the background-size property, which is now supported by most browsers.
To scale the background image to fit inside the div:
background-size: contain;
To scale the background image to cover the whole div:
background-size: cover;
JSFiddle example or runnable snippet:
#imagecontainer {
background: url("http://3.bp.blogspot.com/_EqZzf-l7OCg/TNmdtcyGBZI/AAAAAAAAAD8/KD5Y23c24go/s1600/homer-simpson-1280x1024.jpg") no-repeat;
width: 100px;
height: 200px;
border: 1px solid;
background-size: contain;
}
<div id="imagecontainer"></div>
There also exists a filter for IE 5.5+ support, as well as vendor prefixes for some older browsers.
If what you need is the image to have the same dimensions of the div, I think this is the most elegant solution:
background-size: 100% 100%;
If not, the answer by #grc is the most appropriated one.

You can use this attributes:
background-size: contain;
background-repeat: no-repeat;
and you code is then like this:
<div style="text-align:center;background-image: url(/media/img_1_bg.jpg); background-size: contain;
background-repeat: no-repeat;" id="mainpage">
background-position-x: center;
background-position-y: center;
you also use this:
background-size:contain;
height: 0;
width: 100%;
padding-top: 66,64%;
I don't know your div-values, but let's assume you've got those.
height: auto;
max-width: 600px;
Again, those are just random numbers.
It could quite hard to make the background-image (if you would want to) with a fixed width for the div, so better use max-width. And actually it isn't complicated to fill a div with an background-image, just make sure you style the parent element the right way, so the image has a place it can go into.

try any of the following,
background-size: contain;
background-size: cover;
background-size: 100%;
.container{
background-size: 100%;
}
The background-size property specifies the size of the background images.
There are different syntaxes you can use with this property: the keyword syntax ("auto", "cover" and "contain"), the one-value syntax (sets the width of the image (height becomes "auto"), the two-value syntax (first value: width of the image, second value: height).
percentage - Sets the width and height of the background image in percent of the parent element.
cover - Resize the background image to cover the entire container, even if it has to stretch the image or cut a little bit off one of the edges
contain - Resize the background image to make sure the image is fully visible
For more: https://www.w3schools.com/cssref/css3_pr_background-size.asp
Alternative:
background-size: auto 100%;
you can also try this, set background size as cover and to get it look nicer also set background position center like so :
background-size: cover;
background-position: center ;
This question is very similar to another question, but is not exactly the same in that the code does not have the background shortcut code, but uses the individual rules.
Notes about the layers
Layer 1 is an inline style created by PHP
Layer 2 is my attempt to add the contain value to the layer in the child theme without overriding the PHP.
Layer 3 is the parent theme assigning the cover value to the layer. In Firefox Inspector, the background-size rule shows as being crossed out.
Layer 4 is also part of the parent theme.
element
{
background-image: url(https://montanawebmaster.com/wp-content/uploads/2018/11/Bug.jpg);
}
#masthead .header-image
{
background-size: contain;
}
#masthead .header-image
{
display: block;
width: inherit;
max-width: 100%;
margin: 0 auto;
background-size: cover;
background-position: 50% 50%;
background-attachment: fixed;
}
.kahuna-cropped-headerimage div.header-image
{
height: 100%;
}
This is affecting several sites using the parent theme, but here is an example: https://montanawebmaster.com/images/why-is-the-wordpress-kahuna-theme-messing-with-my-images/ The bug image in the banner should be contained as opposed to cover.
The issue is the background-attachment: fixed.
You'll need to update your css to:
#masthead .header-image {
background-repeat: no-repeat;
background-attachment: unset;
}
With this new change, you may or may not want to set it back to cover.
I use ionic 3.
How to add an id to my background?
ion-content {
background-image: url('../assets/imgs/back.png');
background-size: 100%;
background-repeat: no-repeat; }
So I think you're a bit confused, in CSS classes and IDs both act as selectors and can both use the same CSS properties. Meaning it's not usually necessary to have both on an object. There is nothing wrong with having an ID and a class (or multiple classes) it's just not usually necessary.
See this example: https://codepen.io/samandalso/pen/zaPpve
In it we are using an ID and a class on the same div, but you could easily move all of the CSS rules to one or the other and get the same result. The last selector is a child selector, which is saying and div that is a child of a parent with the class "ion-content" give 100px of padding on all four sides and make the color red. Does that help?
/* Individual selectors */
#myID {
background-size: cover;
width: 100vw;
height: 100vh;
}
.ion-content {
background: url(http://via.placeholder.com/100x100) center center;
text-align: center;
}
/* Child selector */
.ion-content div {
color: red;
padding: 100px;
}
Is there a way in CSS to include a background without using url()
Ex, I can't do this:
#blah {
background:url("either image or image data");
}
Is there a workaround where I can achieve the same thing but not using the keyword "url" (The word "url" is prohibited.
You can use an <img> tag as your background image, no URL in the CSS is necessary. Something like this:
HTML
<img src="image.jpg" class="bg">
<div id="page-wrap">
</div>
CSS
img.bg {
min-height: 100%;
min-width: 1024px;
width: 100%;
height: auto;
position: fixed;
top: 0;
left: 0;
}
#media screen and (max-width: 1024px) {
img.bg {
left: 50%;
margin-left: -512px;
}
}
See here for more information and a demo: http://css-tricks.com/perfect-full-page-background-image/
No, you cannot. That is the way CSS works when including external content. To prohibit the keyword url on the web is a rather strange thing.
No need to make it so complicated !!!
Here is the explanation :
When using the url() value, you have three choices:
relative path based on the root domain of the CSS file — begin with a slash (/) as shown above
relative path based on the immediate directory of the CSS file — no slash (url(path/to/image.png) )
absolute URL, if you are linking to an external resource — url(http://example.com/path/to/image.png)
Source: https://html.com/attributes/body-background/
So basically, if you have your image in the folder image, next to to the foler styles (in which you css file might be), here is what you need to do :
background: url(../images/Chat.jpg)
../ means you go back one level above your current folder/workplace.
Here is what I used:
background: url(../images/Chat.jpg) no-repeat center center fixed;
-webkit-background-size: cover;
-moz-background-size: cover;
-o-background-size: cover;
background-size: cover;
I want that my background image stretch and scale depending on the browser viewport size.
I've seen some questions on Stack Overflow that do the job, like Stretch and scale CSS background for example. It works well, but I want to place the image using background, not with an img tag.
In that one an img tag is placed, and then with CSS we tribute to the img tag.
width:100%; height:100%;
It works, but that question is a bit old, and states that in CSS 3 resizing a background image will work pretty well. I've tried this example the first one, but it didn't work out for me.
Is there a good method to do it with the background-image declaration?
CSS3 has a nice little attribute called background-size:cover.
This scales the image so that the background area is completely covered by the background image while maintaining the aspect ratio. The entire area will be covered. However, part of the image may not be visible if the width/height of the resized image is too large.
You could use the CSS3 property to do it quite nicely. It resizes to ratio so no image distortion (although it does upscale small images). Just note, it's not implemented in all browsers yet.
background-size: 100%;
Using the code I mentioned...
HTML
<div id="background">
<img src="img.jpg" class="stretch" alt="" />
</div>
CSS
#background {
width: 100%;
height: 100%;
position: fixed;
left: 0px;
top: 0px;
z-index: -1; /* Ensure div tag stays behind content; -999 might work, too. */
}
.stretch {
width:100%;
height:100%;
}
That produces the desired effect: only the content will scroll, not the background.
The background image resizes to the browser viewport for any screen size. When the content doesn't fit the browser viewport, and the user needs to scroll the page, the background image remains fixed in the viewport while the content scrolls.
With CSS 3 it seems this would be a lot easier.
CSS:
html,body {
background: url(images/bg.jpg) no-repeat center center fixed;
-webkit-background-size: cover; /* For WebKit*/
-moz-background-size: cover; /* Mozilla*/
-o-background-size: cover; /* Opera*/
background-size: cover; /* Generic*/
}
background-size: 100% 100%;
stretches the background to fill the entire element on both axes.
The following CSS part should stretch the image with all browsers.
I do this dynamically for each page. Therefore I use PHP to generate its own HTML tag for each page. All the pictures are in the 'image' folder and end with 'Bg.jpg'.
<html style="
background: url(images/'.$pic.'Bg.jpg) no-repeat center center fixed;
-webkit-background-size: cover;
-moz-background-size: cover;
-o-background-size: cover;
background-size: cover;
filter: progid:DXImageTransform.Microsoft.AlphaImageLoader(src=\'images/'.$pic.'Bg.jpg\', sizingMethod=\'scale\');
-ms-filter: \"progid:DXImageTransform.Microsoft.AlphaImageLoader(src=\'images/'.$pic.'Bg.jpg\', sizingMethod=\'scale\')\
";>
If you have only one background picture for all pages then you may remove the $pic variable, remove escaping back-slashes, adjust paths and place this code in your CSS file.
html{
background: url(images/homeBg.jpg) no-repeat center center fixed;
-webkit-background-size: cover;
-moz-background-size: cover;
-o-background-size: cover;
background-size: cover;
filter: progid:DXImageTransform.Microsoft.AlphaImageLoader(src='images/homeBg.jpg', sizingMethod='scale');
-ms-filter: progid:DXImageTransform.Microsoft.AlphaImageLoader(src='images/homeBg', sizingMethod='scale');
}
This was tested with Internet Explorer 9, Chrome 21, and Firefox 14.
Use this CSS:
background: url('img.png') no-repeat;
background-size: 100%;
You can actually achieve the same effect as a background image with the img tag. You just have to set its z-index lower than everything else, set position:absolute and use a transparent background for every box in the foreground.
You can add this class into your CSS file.
.stretch {
background: url(images/bg.jpg) no-repeat center center fixed;
-webkit-background-size: cover;
-moz-background-size: cover;
-o-background-size: cover;
background-size: cover;
}
It works in:
Safari 3 or later
Chrome Whatever or later
Internet Explorer 9 or later
Opera 10 or later (Opera 9.5 supported background-size, but not the keywords)
Firefox 3.6 or later (Firefox 4 supports non-vendor prefixed version)
It is explained by CSS tricks: Perfect Full Page Background Image
Demo: https://css-tricks.com/examples/FullPageBackgroundImage/progressive.php
Code:
body {
background: url(images/myBackground.jpg) no-repeat center center fixed;
-webkit-background-size: cover;
-moz-background-size: cover;
-o-background-size: cover;
background-size: cover;
}
In order to scale your images appropriately based on the container size, use the following:
background-size: contain;
background-repeat: no-repeat;
I use this, and it works with all browsers:
<html>
<head>
<title>Stretched Background Image</title>
<style type="text/css">
/* Remove margins from the 'html' and 'body' tags, and ensure the page takes up full screen height. */
html, body {height:100%; margin:0; padding:0;}
/* Set the position and dimensions of the background image. */
#page-background {position:fixed; top:0; left:0; width:100%; height:100%;}
/* Specify the position and layering for the content that needs to appear in front of the background image. Must have a higher z-index value than the background image. Also add some padding to compensate for removing the margin from the 'html' and 'body' tags. */
#content {position:relative; z-index:1; padding:10px;}
</style>
<!-- The above code doesn't work in Internet Explorer 6. To address this, we use a conditional comment to specify an alternative style sheet for IE 6. -->
<!--[if IE 6]>
<style type="text/css">
html {overflow-y:hidden;}
body {overflow-y:auto;}
#page-background {position:absolute; z-index:-1;}
#content {position:static;padding:10px;}
</style>
<![endif]-->
</head>
<body>
<div id="page-background"><img src="http://www.quackit.com/pix/milford_sound/milford_sound.jpg" width="100%" height="100%" alt="Smile"></div>
<div id="content">
<h2>Stretch that Background Image!</h2>
<p>This text appears in front of the background image. This is because we've used CSS to layer the content in front of the background image. The background image will stretch to fit your browser window. You can see the image grow and shrink as you resize your browser.</p>
<p>Go on, try it - resize your browser!</p>
</div>
</body>
</html>
I wanted to center and scale a background image, without stretching it to the entire page, and I wanted the aspect ratio to be maintained. This worked for me, thanks to the variations suggested in other answers:
INLINE IMAGE: ------------------------
<div id="background">
<img src="img.jpg" class="stretch" alt="" />
</div>
CSS ----------------------------------
html {
height:100%;
}
#background {
text-align: center;
width: 100%;
height: 100%;
position: fixed;
left: 0px;
top: 0px;
z-index: -1;
}
.stretch {
margin: auto;
height:100%;
}
Thanks!
But then it was not working for the Google Chrome and Safari browsers (stretching worked, but the hight of the pictures was only 2 mm!), until someone told me what lacks:
Try to set height:auto;min-height:100%;
So change that for your height:100%; line, gives:
#### #background {
width: 100%;
height: 100%;
position: fixed;
left: 0px;
top: 0px;
z-index: -1;
}
.stretch {
width:100%;
height:auto;
min-height:100%;
}
Just before that newly added code I have this in my Drupal Tendu themes style.css:
html, body{height:100%;}
#page{background:#ffffff; height:auto !important;height:100%;min-height:100%;position:relative;}
Then I have to make a new block within Drupal with the picture while adding class=stretch:
< img alt="" class="stretch" src="pic.url" />
Just copying a picture with the editor in that Drupal block doesn't work; one has to change the editor to non-formatted text.
I agree with the image in absolute div with 100% width and height. Make sure you set 100% width and height for the body in the CSS and set margins and padding to zero. Another issue you will find with this method is that when selecting text, the selection area can sometimes encompass the background image, which has the unfortunate effect of making the full page have the selected state. You can get round this by using the user-select:none CSS rule, like so:
<html>
<head>
<style type="text/css">
html,body {
height: 100%;
width: 100%
margin: none;
padding: none;
}
#background {
width: 100%;
height: 100%;
position: fixed;
left: 0px;
top: 0px;
z-index: -99999;
-webkit-user-select: none;
-khtml-user-select: none;
-moz-user-select: none;
-o-user-select: none;
user-select: none;
}
#background img {
width: 100%;
height: 100%;
}
#main{ z-index:10;}
</style>
</head>
<body>
<div id="main">
content here
</div>
<div id="background"><img src="bg.jpg"></div>
</body>
</html>
Again, Internet Explorer is the bad guy here, because it doesn't recognise the user-select option - not even Internet Explorer 10 preview supports it, so you have the option of either using JavaScript to prevent background image selection (for example, http://www.felgall.com/jstip35.htm ) or using CSS 3 background-stretch method.
Also, for SEO I would put the background image at the bottom of the page, but if the background image takes too long to load (that is, with a white background initially), you could move to the top of the page.
I used a combination of the background-X CSS properties to achieve the ideal scaling background image.
background-size: cover;
background-repeat: no-repeat;
background-position: center;
background-attachment: fixed;
This makes the background always cover the entire browser window and remains centered when scaling.
Use the Backstretch plugin. One could even have several images slide. It also works within containers. This way for example one could have only a portion of the background been covered with an background image.
Since even I could get it to work proves it to be an easy to use plugin :).
The following worked for me.
.back-ground {
background-image: url("../assets/background.png");
background-size: 100vw 100vh;
}
that worked to cover the entire background on different dimensions
If you want to have the content centered horizontally, use a combination like this:
background-repeat: no-repeat;
background-size: cover;
background-position: center;
This will look beautiful.
Use this CSS:
background-size: 100% 100%
You can use the border-image : yourimage property to scale the image up to the border. Even if you give the background-image, the border image will be drawn over it.
The border-image property is very useful if your style sheet is implemented somewhere which doesn't support CSS 3. If you are using Google Chrome or Firefox, then I recommend the background-size:cover property itself.
Do you want to achieve this just using one image? Because you can actually make somewhat similar to a stretching background using two images. PNG images for instance.
I've done this before, and it's not that hard. Besides, I think stretching would just harm the quality of the background. And if you add a huge image it would slow down slow computers and browsers.
