How to make a full width image responsive - html

I have an image that is my header. Here is my simple HTML:
<html>
<body>
<div class="wrapper" />
</body>
</html>
It fills the full width of the page, but I had to specify a height for it show up. Here is the css:
.wrapper {
background-image: url(../assets/bridge.jpg);
background-repeat: no-repeat;
background-size: 100%;
width: 100%;
height: 250px;
}
How do I make this image responsive? Right now when I expand the page it gets to the point where the pic is unrecognizable.

Didn't got your question quiet well, but I think you are missing a value here
background-size: 100%; /* 1 value is not wrong but you'll probably need 2 */
--^---
CSS
.wrapper {
background-image: url(http://images.google.co.in/intl/en_ALL/images/logos/images_logo_lg.gif);
background-repeat: no-repeat;
background-size: 100% 100%;
width: 100%;
height: 250px;
}
Demo
As ralph.m suggested, if you are using this image as your website background, than use the background property on body element instead of div
You need to use following CSS to make the background responsive
body {
background: url(bg.jpg) no-repeat center center fixed;
-webkit-background-size: cover;
-moz-background-size: cover;
-o-background-size: cover;
background-size: cover;
}

You need to think carefully about how you want/expect this to work. Without some actual content in the div, it will have zero height, which is why you needed to set a height on it; but in general, try to avoid setting heights. Presumably, if this is a "wrapper", it will be wrapping some content that will hold it open without you having to set a height.
As for the background image, you need to think about how it will behave. Do you just want it to appear in a strip along the top? If you use Mr Alien's solution, be aware that the image will stretch wider and wider and start to look odd. So we need some more information on what you are trying to do here.

Make background image fill background

This seems to be a common question but the existing answers I see do not seem to work for me. I have a background image that is much taller than it is wide. I would like the height to be 100% of the height of body. So far I have tried:
body, html {
height: 100%;
min-height: 100%;
}
body {
background:url("NewLogo.png") no-repeat center center;
background-size: 100% auto;
}
I have also tried changing background-size: cover; but this also just makes the image large but cuts off the top and bottom.
Use contain. This will guarantee that the entire image appears in the container, and nothing is cut off:
body {
background:url("NewLogo.png") no-repeat center center;
background-size: contain;
}
Please note that if you want to have a background image which is cover and has got it's own height (without just being large, as wide as your browser but loosing the top & bottom as you said), you can try giving an appropriate height in vh to your background image.
body {
margin: 0;
}
#image {
background-image: url(https://images.unsplash.com/photo-1504387103978-e4ee71416c38?auto=format&fit=crop&w=2134&q=60&ixid=dW5zcGxhc2guY29tOzs7Ozs%3D);
background-repeat: no-repeat;
height: 293vh;
background-size: cover;
}
<div id="image">
</div>
Otherwise if you just want to make your background image cover, or if you want make it contain(though your image wouldn't fit the browser wide, it would be in it's real height), you can visit the following link:

I can't figure out why 100% width doesn't work with a background image

I'm trying to create a webpage. I'm having a little difficulty
with getting my background picture to show up. I had it up and running, but I decided I wanted to give it a responsive design, and I can't figure it out. This is my code for the image:
<style>
body .title_img {
background-image: url("SplashScreen.jpg");
height: auto;
width: 100%;
background-position: center;
z-index: -1;
}
</style>
<div class="title_img">
<!-- Background Splash Screen -->
</div>
If I give the height/width a definitive size (pixels) it shows up. I don't understand why 100% width with auto height wouldn't give me a picture that is 100% the size of the body (which I THINK i have made sure it was the 100% of the html document) and a height that is automatically proportional to the width. Can someone explain what I'm doing wrong?
EDIT- Added the HTML code.
Full-Page Background Images
I think what you are trying to create, is a full-page background image for your website. Based off of reading the code you provided, I believe you want something that does the following:
Fills entire page with image, no white space
Scales image as needed
Retains image proportions (aspect ratio)
Image is centered on page
Does not cause scrollbars
As cross-browser compatible as possible
Isn't some fancy shenanigans like Flash
If that is what you are trying to create, then I found a few lines of code that could help. Here is an example of how you could go about doing this with your image using css:
CSS File (That's where the magic happens):
html {
background: url("SplashScreen.jpg") no-repeat center center fixed;
-webkit-background-size: cover;
-moz-background-size: cover;
-o-background-size: cover;
background-size: cover;
}
Just make sure your html file is setup correctly to use the css file, and it should create a cool background image you can use for your websites.
You can read more into this here and learn more about what makes this work.
Try setting height: 100% in body and html in your css:
html, body {
height: 100%;
}
And then put background-size: cover in body .title_img:
body .title_img {
background-image: url("SplashScreen.jpg");
height: 100%;
background-position: center;
background-repeat: no-repeat;
background-size: cover;
z-index: -1;
}
See reference here.
Use
background-size: cover
or
background-size:100% 100%.
with
background-repeat: no-repeat
That will set it to 100% of its container.

How to create a full screen div on landing page

I am creating a website, however I would like the website to have a full screen div (Like this: http://peet.io)
However I do not know what is wrong with my code, I have tried googling several times, but still no help.
This is my code:
http://jsfiddle.net/6p3dk2yo/
.introduction {
height: 100%;
width: 100%;
background: url('../images/header.jpg') no-repeat center center;
-webkit-background-size: cover;
-moz-background-size: cover;
-o-background-size: cover;
background-size: cover;
background-position: absolute;
}
That is my introduction css code.
However it only show's my test div and not my introduction div which is what I need the most, is not showing, the 'test' div is making it hidden.
If anyone knows how i can fix this then please say:)
That is because setting height: 100% simply means "stretch to the height of element's content". And since it is an empty <div> element, a height of 100% simply computes to 0px.
What you can do though, is to use vw or vh units when it comes to dimensions (see browser compatibility and support) that have to be calculated relative to the viewport size:
.introduction {
height:100vh;
width: 100%;
background: url('../images/header.jpg') no-repeat center center;
-webkit-background-size: cover;
-moz-background-size: cover;
-o-background-size: cover;
background-size: cover;
position: relative;
}
http://jsfiddle.net/teddyrised/6p3dk2yo/3/
Even better, is that you can also use max-height or min-height to control how big the element should be when it comes to smaller, mobile viewports through the #media conditional statement.
Your introduction div has a height: 100%; but it's 100% of nothing.
If you put some content in your div, like in this JS Fiddle then you'll be able to see the background image.
If you don't want any content in the div, then you should change height to a fixed pixel amount, like height: 500px;.
Your div technically has no content, so it is in fact 100% of 0px (content size). If you want to stick with the percentages and keep things responsive as you are, why not throw an actual image in that div containter? Check out this Jfiddle. -> http://jsfiddle.net/6p3dk2yo/
<body>
<section class="introduction"></section>
<section class="test"><img src='../images/header.jpg' alt='header' /></section>
<script src="javascript/smoothscroll.js"></script>
</body>

HTML/CSS background-image not displaying?

I am just trying to set my background but this image will not work. It is between 15 to 20MB in size so I tried to turn it into 5MB. Still no luck. I made a really small image, 25KB size, and that worked but just repeated. My localhost will not show big images either. Is there some limit? What do I need to do to get a full image page?
body {
background-image:url(background.jpg);
}
Do this to avoid repeating the image:
body
{
background-image:url(background.jpg);
background-repeat:no-repeat;
}
You can also experiment with background-size: cover like this:
body
{
background-image: url("http://www.google.com/doodle4google/images/carousel-winner2012.jpg");
background-repeat: no-repeat;
background-position: center center;
-moz-background-size: cover;
-webkit-background-size: cover;
-o-background-size: cover;
background-size: cover;
background-attachment: fixed;
}
Here's a demo at JS Bin with a beautiful Doodle 4 Google as the background image to test the behavior:
http://jsbin.com/ivexah/2
you need to assign a width and height to body.
for example:
html, body {
width: 100%;
height: 100%;
}
You can use the shorthand background css property:
background: url(background.jpg) no-repeat;
Also your body might not have a height of 100% because there's no content on your page. Either give your html and body a height of 100% or add more content to your page.
To make a background image cover its entire container use background-size:
background-size: cover;
IE8 and lower don't support this. For those browsers you need a javascript fallback. There's an excellent article on css-tricks.com that shows different techniques.
You shouldn't have any "size" limitation on your background image. More than likely, you're file is so large that you are not waiting long enough for it to load OR you have not set a width and height. Without the dimensions, the element tahat you are trying to load the background image will essentially have a size of 0px x 0px. See the following jsfiddle example:
http://jsfiddle.net/GymxW/1/
The HTML:
<div class="container"></div>
The CSS:
.container {
width: 400px;
height: 100px;
background-image: url(http://dummyimage.com/400x100/4d494d/686a82.gif&text=background+image);
background-repeat: none;
background-position: 0 0;
}
IMPORTANT: If you are wanting to have an image that is "stretched" to the full size of the viewport, a simple solution is to use a plugin, such as Backstretch.

Background size issue?

I have a giant background image that I need 100% 100% scale. But my problem is if the webpage is say 150% height that of the browser (so browser is say 1000x1000, and my website is 1000x1500) when you scroll down to see the rest of the website the background repeats and doesn't get scaled down.
My css is
html,body { width: 100%; height 100%; }
body { background: url(blah) no-repeat; background-size: 100% 100%; }
Any idea of how I can fix that?
Here is a great resource on that topic.
http://css-tricks.com/perfect-full-page-background-image/
Hope it helps.
Like the CSS-Tricks article explained, you could change the CSS to:
html {
background: url(images/background.jpg) no-repeat center center fixed;
-webkit-background-size: cover;
-moz-background-size: cover;
-o-background-size: cover;
background-size: cover;
}
This will make sure your background image covers the whole page, but is only supported in CSS3. Like above, you need to include specific code for each major browser.
Alternatively, try just using:
height: 100%;
or
width: 100%
depending on the image size in relation to your page, but this should let the image resize to the right height/width of your page, while nicely maintaining aspect ratio.
Try applying the background image to the html instead.
Just set 100% on the width if its smaller then the height otherweise set the height 100%. You could probably fix that with javascript.
