Info: I have a cropped image used as a background image for the top of my webpage. In CSS I've defined in px the size of a div containing the image - which is cropping the image. (I'm doing this in Squarespace). So when you enter the page you see the background image (and some text) filling the screen and you then scroll down past the image.
The problem: when I reduce the size of the web browser window the div, of course, maintains the same px height. This means the image ends up being background for most of the page - I just want it to be on the top when you enter the page.
The question: how do I make the cropping div responsive in height? As far as I have researched I can only set the value in px which isn't responsive-friendly... The following code is based on my external screen size. So I need that height px for large screens.
My code:
.header-background {
position: absolute;
top: -160px;
left: -335px;
right: -335px;
height: 850px;
z-index: -1;
overflow: hidden;
background-size: cover;
background-position: center;
background-image: img src('/s/Sams-sort.png')
Give it to a free height that takes up the higher space only
height:auto

Struggled for a solution the first time so I am posting again with more info. Thanks in advance for your feedback.
On the website I am building at the moment I have 2 background images set to 2 different divs but they need to line up perfectly on all devices.
At the moment the background images line up at 1920px wide and smaller but once you start going larger than that it starts shifting.
Please could someone help?
Please see an image here that it should resemble
.productTopSection {
background: url("http://mcauliffe.testcre8.co.uk/assets/images/home/mcauliffe-brownfield-experts-homepage-about-image.jpg") no-repeat center;
min-height: 895px;
background-size: auto 100%, cover;
}
.mc-key-points {
background: url("http://mcauliffe.testcre8.co.uk/assets/images/home/mcauliffe-brownfield-experts-homepage-key-points-image.jpg") no-repeat center;
min-height: 895px;
background-size: auto 100%, cover;
}
#media only screen and (min-width: 1921px) {
.productTopSection {
background: url("http://mcauliffe.testcre8.co.uk/assets/images/home/mcauliffe-brownfield-experts-homepage-about-image.jpg") no-repeat center center;
min-height: 895px;
background-size: cover;
}
.mc-key-points {
background: url("http://mcauliffe.testcre8.co.uk/assets/images/home/mcauliffe-brownfield-experts-homepage-key-points-image.jpg") no-repeat center center;
min-height: 895px;
background-size: cover;
}
}
#media only screen and (max-width: 1200px) {
.productTopSection {
background: url("http://mcauliffe.testcre8.co.uk/assets/images/home/mcauliffe-brownfield-experts-homepage-about-image-mobile.jpg") no-repeat center center;
background-size: cover;
}
.mc-key-points {
background: none;
}
}
<div class="productTopSection g-py-200">
<!-- Content Goes Here -->
</div>
<div class="mc-key-points g-py-200">
<!-- Content Goes Here -->
</div>
#media only screen and (max-width: 767px)
.productTopSection {
background-size: cover;
height: 200px;
min-height: auto;
}
since then there is no content i think the above is the way.correct me if i'm wrong
Your example does not work, well, it doesn't matter, I'll try to understand you
First he trumpets to understand how it works
The blue frame is your div in full screen mode (one element for the whole page)
since the div has no height, you give it a min-height or fixed height (height property) in your case it works the same with only a background and until you put something in the div
At this stage, you need to understand that the height you specify does not affect the height of the image itself, that is, the min-height will not change until you put a lot of text in it (this is just an example, you can put whatever you want that has a height)
In the image I have demonstrated the background-size property with 100% auto value.
from the documentation we see that we set 100% width and leave the height on auto also by default the bakcground-image has the same position (background-poistion: 0% 0%)
If you write it all like this:
background-size: 100% auto;
background-position: 0 0; // this is not required as this is the default, I am just using this as an example
we will get the result as in the picture above, where the picture will be stretched in width relative to the screen
well now we reduce the width of screen (div automatically starts changing width and taking the width of the screen)
what do we see? there is an empty space below! In your case you set the height to 100% and the width automatically
background-size: auto 100%;
and yes, you shouldn't use multiple background image syntax in your case
background-size: auto 100%, cover; // you have one background image
This is what your non-working result looks like:
Note that I can see that you are using center positioning, so you have two holes! With what I congratulate you!
What should you do? You must use an image (html img tag) instead of a background
Example:
<img aria-hidden="true" class="bg-fix" src="https://i.picsum.photos/id/767/1200/800.jpg?hmac=lGBpi_Bt_UPPi17TX-TUBQitEe14QlbeSJ-GYhwZBvw" alt="">
<style>
img {
display: block; // Remove inline native space
width: 100%;
}
</style>
or use media to control the div's height (use vh instead of pixels or css media queries)
<style>
div {
/*.....*/
-webkit-background-size: 100% auto;
background-size: 100% auto;
min-height: 60vh;
}
/* OR */
div {
/*....*/
min-height: 875px;
}
#media screen and (max-width: 1024px) {
div {
min-height: 500px;
}
}
</style>
While it's not clear to me if you were planning to crop the image sides on mobile, I think this may help out at least - for something like this I think you can make it much easier by using an <img> tag in HTML instead of background-image in CSS.
The problem is getting the height to scale proportionally to the width so that the images retain their aspect ratio. What's happening in your code is the height is effectively being set to 895px with the min-height, it will not go higher unless you add enough content to the div.
So starting with mobile screens, your height is still 895px and the sides of the images will be cropped less and less until you reach 1920px in width (the image width). Once you go over this the image will start to stretch wider to cover and the top/bottom will start to be cropped. That top/bottom cropping while the images are centered is what causing the edges in the image to not line up. Because you're now lining up say 20% up on the top image to 20% down on the bottom one when you planned for 0% to line up.
So how does the <img> tag make this easier?
It adds content width/height to your container and allows the container to expand to fit the content, or force the content to shrink to fit in it. if you just throw an img in a div you'll see it expands the div out to the dimensions of the img.
But if you set the width to 100% on both the container and the img, it will fill the width of the container. The key being that the height will be proportionally set to maintain the aspect ratio and the div will expand in height to fit the img height needed and you will not have any top/bottom cropping so edges will line up.
Then you just need an absolute positioned container over the img to put your text content wherever you want.
If you were trying to crop the image sizes on small screens (which I think would look better). I'd suggest you use media queries there just to set some breakpoints where maybe the image is 120% width on phones and center - you'll still have that height though so if it's too high and you need to crop to bring the height down, I do have an idea for that but don't want to scope creep too much...
Here's an example with <img> - much less going on here and more straightforward IMO. And you gain more control - you can tweak this a lot to crop however you want at different media queries.
.productTopSection, .mc-key-points {
position: relative;
width: 100%;
}
.responsive-img {
width: 100%;
}
.overlay-content {
position: absolute;
/* just to get started with the content positioning */
top: 50%;
transform: translateY(-50%)
}
<div class="productTopSection g-py-200">
<img class="responsive-img" src="http://mcauliffe.testcre8.co.uk/assets/images/home/mcauliffe-brownfield-experts-homepage-about-image.jpg">

I have few pages where I have included a background image with width 100% and height 100% in every page. That means whenever a page is loaded you'll see an image with 100% screen's size. Everything is perfect when I see these pages in my laptop. I'm facing problems when I view them in mobile screens.
I just want to know how do everyone deal in these situations. I mean how to make changes to my main div with width and height 100% in responsive screens?
The image is getting stretched if I set the background size to 100%.
Some part of the image is cut if I set the background size to contain.
I want the image's clarity should be perfect. Should I make the width of the main div to auto? Or else should I change the image in responsive screens?
Is there anyway to make this div look better in small screens?
I just want my main div to be apt in Responsive screens.
It shouldn't look line there is a defect in the image or in my code.
Here's my code of the main div :
html,
body {
width: 100%;
height: 100%;
}
.main-div {
width: 100%;
height: 100%;
background-image: url('http://vignette4.wikia.nocookie.net/marveldatabase/images/8/8c/Wolverine_Vol_3_73_Variant_Frame_Textless.jpg/revision/latest?cb=20090925123509');
}
<div class="main-div">
</div>
There are many options to make image responsive. Please Google out the approach that best suits your requirement. The solution which you will find helpful depends on the image that you are using. It depends on the size and quality of image.
I find the following links helpful.
https://www.w3schools.com/css/css_rwd_images.asp
https://www.w3schools.com/bootstrap/bootstrap_ref_css_images.asp
For Responsive Image
.class_name{
max-width: 100%,
height: auto,
display:block
}
And Full Screen Responsive Image use individual class like
.class_name{
background-image: url(image path) ;
background-position: center center;
background-repeat: no-repeat;
background-attachment: fixed;
background-size: cover;
background-color: #999;
}
html,
body {
max-width: 2000px;
min-width: 100px;
height: auto;
}
.main-div {
width: 100%;
height: 100%;
background-image: url('http://vignette4.wikia.nocookie.net/marveldatabase/images/8/8c/Wolverine_Vol_3_73_Variant_Frame_Textless.jpg/revision/latest?cb=20090925123509');
}
<div class="main-div">
</div>
this should make it responsive. I don't know what you want the DIV to be like, so I left that alone.
Im trying to design a home page for my website where im using a div to show an illustration.
i want to use an image with the div that covers the entire size of the div.
the image dimensions are 1920x850.
this is the code for the div
<div class="custom-col col-md-12 col-sm-12" id="widget-static-block-1"></div>
the css:
#widget-static-block-1 {
background: url({{ d_banner1.jpg' | asset_url }});
width:100%; }
i want to be able to view the image on different screen sizes , but the it always gets cut off (either height or width)
ive tried playing around with height and width attributes to no luck.
If i set height:850px; then obviously it shows perfectly on a 1080p sceen but gets cut off on a smaller screen.
One thing i want to be clear about is that i want the entire image to show at all times at all browser sizes, i dont want it to be cut off via height or width.
Try background-size: 100% 100% or background-size: 100vw 100vh. If you want to be certain your div suits every media you can use vw and vh units.
It seems like you're asking for the div to fill the parent (height or width). And if you don't want the background image to appear cropped, you need to maintain the aspect ratio.
This looks what you need: Maintain aspect ratio of div but fill screen width and height in CSS?
Working example
Add styles to div with background:
background-repeat: no-repeat;
background-position: center center;
background-size: cover;
You can resize window to see result.
html, body {
position: relative;
height: 100%;
margin: 0;
}
div {
position: absolute;
width: 100%;
height: 100%;
top: 0;
left: 0;
background: url('http://ghk.h-cdn.co/assets/16/09/980x490/landscape-1457107485-gettyimages-512366437.jpg');
background-repeat: no-repeat;
background-position: center center;
background-size: cover;
}
<div>
</div>
I'm writing an html page with parallax using stellar.js.
In CSS I use:
html, body {height: 100%;}
#slide1 {
height: auto;
background-image:url('../images/1.jpg');
background-color:#fff;
background-repeat: no-repeat;
background-size: cover;
background-attachment: fixed; }
But the image is cut and the bottom of the image is not visible.
Is it possible to set the height of the section (#slide1) to show all the image?
Using background-size:cover; will always crop your background image either vertically or horizontally, except when the element has the exact same h/w ratio as the image. The key is to choose and position the background in such manner that it still looks good when it is cut.
Most likely, you want to give your element a min-height, e.g.:
#slide1 {
min-height: 600px;
}
Keep in mind the most popular desktop ratio is 16:9 and most mobile devices are held vertically. If necessary, use #media queries for different device/viewport widths.
If you don't want your slide to have a larger height than the viewport height (deviceScreen|browser height), add max-height: 100vh!important; to the above rule (useful on mobile devices).
Try setting #slide1 height property to 100% instead of using auto.
I'll be working with full-screen banners, just like this one or this other one and for this purpose I'm using a plugin in a Wordpress site.
Now I have set their respective widths to 100% (to avoid an x-axis scrolling and also to make the banners display fully on every screen size). Problem is that if you grab your browser screen to make it smaller or you open the web site on small screens (13 inch or iPads) the images displayed on banners squish.
I need the image to be cutted off while resizing and the only way I know for that is to change the banner's div class from width: 100% to width:the amount of pixels I want but in this way, obviously, if the screen from where you enter the site is smaller you'll get a x-axis scrolling and if it's bigger you'll have the banner cutted of when it reaches the amount of pixels previously set up in it's width.
How can I get the images not to squish, but to get cutted off making it's div width display 100% on any browser?
Banner's actual code:
.bannercustom {
position: relative;
z-index: 11;
left: -2px;
width: 100%;
top: 0px;
float: left;
height: 440px;
}
Do you have the ability to set the banner as a background-image to a div? Then you can set the background-scale to 100% and let the div resize as needed.
Why not just use: width:auto; ?
Should work.
