How to make background image take full width without cropping? - html

We have set an image as a background image using the following code below and place text on top of it. Is there a way to display the image as a background without the "cropping" regardless of the height of the content on top of the image?
A pattern that occurs is that as the content grows so does the height of the image. If the solution requires that we get rid of that, then I am okay with that.
Note: images will not always be the same size.

By using a percentage value in padding-bottom value, the percentage is calculated from the width of the element, not from height, as one might think.
Which means
padding-bottom: 42.773%; /* (438 × 100 / 1024) */
... will always have a minimum height allowing it to display the uncropped image (which, in your case has 1024px × 438px).
.min-ratio {
padding-bottom: 42.7%; /* (height × 100 / width) */
background-size: contain;
background-position: bottom center;
background-repeat: no-repeat;
width: 100%;
position: relative;

However, you'll need to stop the image from repeating vertically, using background-repeat:no-repeat so that when the div gets too tall (on mobile, for example) it doesn't repeat the image.
The above technique allows you to set a minimal ratio on an element, without having to hard-code width or height values across different #media responsiveness intervals.
Since stack snippets looks down, here's the fiddle: https://jsfiddle.net/websiter/mek0chne/4/

You could use an padding in .banner
.banner {
position: relative;
display: block;
padding : 50px 0;
}

one way to do this if you don't know what's the height of the image is going to be , you can use an image instead of a div with background and set its position to absolute : Fiddle
.banner {
position: relative;
display: block;
}
.banner:after {
content: '';
width: 100%;
height: 100%;
position: absolute;
bottom: 0;
left: 0;
}
.banner__image {
width: 100%;
height: 100%;
background-position: center;
background-size: cover;
position: absolute;
top: 0;
left: 0;
z-index: 1;
}
.banner__content {
padding: 200px;
position: relative;
max-width: 900px;
text-shadow: 0 0 20px rgba(0,0,0,.6);
margin: 0 auto;
padding: 0 15px;
z-index: 2;
color: white;
}
#bg{
position: absolute;
width: 100%;
}
<div class="banner">
<!--
<div class="banner__image" style="background-image: url('https://media.istockphoto.com/vectors/people-large-group-vector-id519533182')"></div>
-->
<img src="https://media.istockphoto.com/vectors/people-large-group-vector-id519533182" id="bg"/>
<div class="banner__content">
<h1>Compellingly seize high-payoff supply chains</h1>
<h2>Compellingly underwhelm extensive technology rather than low-risk high-yield manufactured products. Phosfluorescently brand just in.</h2>
</div>
</div>

You should look at the max and minimum height attributes in css for your class:
.banner
in addition you can also look at the background-repeat css attribute to prevent the image from repeating or alternatively to repeat on both or only on the x or y axis.
I can provide some code if you like but these are very self explanatory, there may be more elegant solutions but this will help you achieve what you're looking for.
Repeat:
https://www.w3schools.com/cssref/pr_background-repeat.asp
Height:
https://www.w3schools.com/cssref/pr_dim_min-height.asp
https://www.w3schools.com/cssref/pr_dim_max-height.asp

Then do not use the image as a background image. Use it as an normal image.
<div class="banner__image">
<img src="url of the image">
</div>
<div class="banner__content">
<!-- Your content here -->
</div>
And for the CSS
.banner__image img{
position:absolute;
width: 100%;
height: 100%;
top: 0;
left: 0;
z-index: 2;
}
.banner__image{
position: absolute;
z-index: 1;
height: 100%;
width: 100%;
}
.banner__content{
z-index: 3;
}
Now this should work

How to use img tag as background of banner with interactable content?

I want to use an img on my page as background-image of an image-slide banner. The reason is to include alt-text for accessibility reasons. To move the img in the background, I have to give it a negative z-index. Otherwise, it always shows on top of the content.
Tag-Lines are included on the banner as h1 titles. These titles can't be selected or interacted with, once the banner is in the negative z-index. So far, there is no problem. However, some of the background-images I want to include on some pages, were not taken by myself, so they need an image credit. The link which leads to the original-photo on the image-credit can't be clicked on. Optically, it's shown above the image and the banner, but it can't be clicked on.
So is there a way to make the content of the banner interactable. I could include the image as background-image, but in this case, how can I include alt-text to the background-image?
.slider {
width: 100%;
position: relative;
height: 600px;
z-index: -1;
}
.banner {
overflow: hidden;
display: flex;
align-items: center;
justify-content: center;
position: absolute;
top: 0;
left: 0;
width: 100%;
height: 100%;
}
.banner-image {
position: fixed;
top: 0;
left: 0;
object-fit: cover;
width: 100%;
height: 640px;
z-index: -2;
}
.image-credits {
background-color: black;
color: white;
padding: 2px 8px;
margin: 10px;
position: absolute;
bottom: 0;
right: 0;
}
.image-credits a {
color: white;
}
<div class="slider">
<div class="banner">
<img class="banner-image" src="https://via.placeholder.com/1280" alt="Description, what you see">
<div class="content">
<h1>Some tagline</h1>
<p class="image-credits">Photo by <a href="image-source" target="blank">Photographer</a\></p>
</div>
</div>
</div>
I tried setting the page up with positive z-values. But then the background-image always shows on top of the rest of the content on the page, and the content remains interactable. Also, I applied pointer-events:none; to all other elements of the slider, except of the image-credits. That also didn't work out.
Seems its not workin when you set z-index both parent and child elements. Try to remove z-index from .slider and it should work.
If you specify z-index on an element, it gonna impacts his descendants too. If you specify a negative z-index, then the corresponding elements are going "behind" <body> element. Then all your click are on <body> element. As <body> have a transparent background, you could have the impression click on your link, but you are not.
To be able to click on your link, it should have no element with greater z-index in front. Below, I have made you an example without z-index on .slider (which is one of the ascendants of your link, so it specifies indirectly z-index for him)
.slider {
width: 100%;
position: relative;
height: 600px;
}
.banner {
overflow: hidden;
display: flex;
align-items: center;
justify-content: center;

width: 100%;
height: 100%;

top: 0;
left: 0;
object-fit: cover;
width: 100%;

z-index: -2;
}
.image-credits {
background-color: black;
color: white;
padding: 2px 8px;
margin: 10px;
position: absolute;
bottom: 0;
right: 0;
}

HTML CSS can't make image fit screen diagonally

I don't have much knowledge about html and css and I couldn't find the answer on the internet so I am here.
Problem:
I am trying to make an image fill top part of the screen but one thing stops me from it and it's the default margin of the <body>. I've managed it by using margin: -10px; But now the image can't fill the screen by 20px, probably because there is no margin, image still thinks screen is that big.
html,body {
width: 100%;
height: 100%;
margin: -10px;
padding: 0;
overflow: hidden;
}
img {
width: 1600px;
height: 300px;
opacity: 70%;
object-fit: cover;
object-position: top 10px;
}
.cont {
position: relative;
text-align: center;
padding: 10px;
}
.main-text {
font-size: 100px;
color: white;
position: absolute;
top: 100px;
left: 70px;
}
<body>
<div class="cont">
<img src="https://i.stack.imgur.com/DWZAk.jpg">
<div class="main-text">Big Ass Title</div>
</div>
</body>
NOTE: If you have any questions or didn't understand anything about the question, please ask because I am ready for any answer. :) Thanks.
If your image is meant to be a decoration(design), then background is fine to use.
.cont can be a flex or grid element, to avoid position absolute and possible unwanted sides effects.
here an example with a background and grid:
body {
margin: 0;
min-height: 100vh; /* optionnal if it does not have a purpose */
}
.cont {
height: 300px; /* guessed from your code */
display: grid; /* default make a single column*/
background: url(https://picsum.photos/id/1015/600/300) 0 0 / cover; /* background covering */
}
.main-text {
margin-block: auto; /* vertical-centering in its row from here */
margin-inline-start:70px;
font-size: 100px; /* from your code */
color: white; /* from your code */
font-weight: normal; /* you looked for this? */
text-shadow: 0 0 1px #000; /*Optionnal increase readability*/
}
<div class="cont">
<h1 class="main-text">Big Ass Title</h1><!-- if that's a title, then make it a title ;) -->
</div>
Generally to eliminate all the margins and paddings you can add:
* {
margin: 0;
padding: 0;
}
By the way I attached a snippet where it's working as you requested. Is better to eliminate the margins than adding a negative margin, if you want to do it that way you must to compensate it in the width to achieve the 100% width intended.
html,
body {
width: 100%;
height: 100%;
padding: 0;
margin: 0;
overflow: hidden;
}
img {
width: 100%;
margin: 0;
height: 300px;
opacity: 70%;
object-fit: cover;
}
.cont {
position: relative;
text-align: center;
}
.main-text {
font-size: 100px;
color: white;
position: absolute;
top: 100px;
left: 70px;
}
<html>
<body>
<div class="cont">
<img src="https://images2.alphacoders.com/941/thumb-1920-941898.jpg">
<div class="main-text">Big Ass Title</div>

How to fix position of the element relative to window size

I have a single image (a checkmark) on the page and I want to fix its position when the user resizes the browser or go fullscreen.
As you can see here the image is moving around the page when I try to resize the browser:(image is the checkmark)
And when I resize the browser again:
The desired result is to fix the position of the image like that play button in the middle of the page that moves relative to the window.
Here is the CSS of the image:
Note: I need those viewport units for some complicated reason! and the absolute positioning is prefered.
#Image{
position: absolute;
max-width:10%;
height: auto;
opacity: 1;
top: 78vh;
left:26.5vw;
z-index: 1000;
}
<img id="Image" src="https://round-arm-authority.000webhostapp.com/test/Changed.png"/>
Update: using this seems to work fine but the image resizes Non-proportional:
#correctImage{
position: absolute;
transform: scale(0.2, 0.2);
height: 100vh;
width: 100vw;
opacity: 1;
z-index: 1000;
}
Update 2: Here is the link to download the zip files to test the code in the browser (Chrome is preferred). The HTML code to modify is in story_html5.html lines 22 - 27 and the CSS code is in correctImageStyle.css.
The desired behavior is just resizing and repositioning of the checkmark image like the play button in the center of the page.
http://s6.picofile.com/d/8381556034/1ef7bc07-eea8-4e9e-8bd8-57214a1e7ef8/Untitled1_Storyline_output.zip
Change the max-width: 10%; to width: 10%
#Image{
position: absolute;
width:10%;
height: auto;
opacity: 1;
top: 78vh;
left:26.5vw;
z-index: 1000;
}
<img id="Image" src="https://round-arm-authority.000webhostapp.com/test/Changed.png"/>
Maybe you should try to force your image to always be on the middle of the screen with:
#Image{
position: fixed;
top: 50%;
left: 50%;
transform: scale(0.2);
height: 100vh;
width: 100vw;
opacity: 1;
z-index: 1000;
}
<img id="Image" src="https://round-arm-authority.000webhostapp.com/test/Changed.png"/>
This should work
html,body,* {
margin: 0;
padding: 0;
box-sizing: border-box;
overflow: hidden;
}
.container {
position: relative;
display: flex;
justify-content:center;
align-items:center;
width: auto;
height: auto;
}
img.image {
width: 80%;
height: 250px;
display: block;
background: grey;
}
.logo {
height: 64px;
width: 64px;
position: absolute;
}
<div class="container">
<img class="image"/>
<img class="logo absolute" id="Image" src="https://round-arm-authority.000webhostapp.com/test/Changed.png"/>
</div>
With ::after
html,body,* {
margin: 0;
padding: 0;
box-sizing: border-box;
overflow: hidden;
}
img {
width: 80%;
height: 250px;
display: block;
background: grey;
}
.container {
position: relative;
display: flex;
justify-content: center;
align-items:center;
}
.container::after {
content: "";
background-image: url("https://round-arm-authority.000webhostapp.com/test/Changed.png");
background-position: center center;
background-size:contain;
background-repeat: no-repeat;
position: absolute;
height: 64px;
width: 64px;
z-index: 1;
}
<div class="container">
<img class="image"/>
</div>

Is it possible to make an image as small as possible while still filling its container, and keeping its aspect ratio?

I have a container of a given size, and I have an image inside it. I want the image to expand to either 100% height or 100% width, depending on whichever comes last, and I want it to keep its aspect ratio, so anything sticking on over the container is cropped off. If it's cropped on the sides, I'd also like it to be centered.
So to be clear, if it's a very wide picture, it would have height: 100%, and if it's a very tall picture, it would have width: 100%.
For example, here's the container and the image, with is neither sized correctly, nor centered:
https://jsfiddle.net/y5px1ch9/1/
<div class="wrapper">
<img src="https://upload.wikimedia.org/wikipedia/commons/thumb/f/f1/S%C3%A4ugende_H%C3%BCndin.JPG/800px-S%C3%A4ugende_H%C3%BCndin.JPG" class="picture">
</div>
.wrapper {
position: relative;
left: 40%;
width: 100px;
height: 200px;
border: 1px black solid;
overflow: hidden;
text-align: center;
}
.picture {
position: relative;
min-height: 100%;
min-width: 100%;
height: auto;
width: auto;
margin: auto;
left: 0;
right: 0;
background-position: center;
}
Anyone know if this is possible to do with CSS?
Since you have a fixed size wrapper, and as object-fit does not have that good browser support, I suggest you use background/background-size on the wrapper
Now, by setting its position, you control where it should get cropped. In below sample I used left top, which means it crops at right/bottom, and in your case, you might want center center, which will crop equally top/bottom or left/right, based on which of the two overflows.
Updated based on a comment
One can also set the image source in the markup, just how one do with the img, here done by setting background-image: url() inline.
.wrapper {
position: relative;
left: 40%;
width: 100px;
height: 200px;
border: 1px black solid;
overflow: hidden;
text-align: center;
background-repeat: no-repeat;
background-position: left top;
background-size: cover;
}
<div class="wrapper" style="background-image: url(https://upload.wikimedia.org/wikipedia/commons/thumb/f/f1/S%C3%A4ugende_H%C3%BCndin.JPG/800px-S%C3%A4ugende_H%C3%BCndin.JPG)">
</div>
And here is the version using object-fit
.wrapper {
position: relative;
left: 40%;
width: 100px;
height: 200px;
border: 1px black solid;
overflow: hidden;
text-align: center;
}
.picture {
position: relative;
height: 100%;
width: 100%;
object-fit: cover;
object-position: left top;
}
<div class="wrapper">
<img src="https://upload.wikimedia.org/wikipedia/commons/thumb/f/f1/S%C3%A4ugende_H%C3%BCndin.JPG/800px-S%C3%A4ugende_H%C3%BCndin.JPG" class="picture">
</div>
It is possible but you have to know the aspect ratio beforehand, knowing this you can reserve space for the image
div {
width: 100%;
overflow:hidden;
position:relative;
}
div::after {
padding-top: 56.25%; /* percentage of containing block _width_ */
display: block;
content: '';
}
div img {
display: block;
width:100%;
height:auto;
position: absolute;
top: -9999px;
bottom: -9999px;
left: -9999px;
right: -9999px;
margin: auto;
}
<div>
<img src="https://placehold.it/200x300"/>
</div>
The main trick is the padding-top: 56.25%;... the aspect ratio
If you define the image as a background-image, then you can use background-size: contain - this does what you want:
.wrapper {
position: relative;
left: 40%;
width: 100px;
height: 200px;
border: 1px black solid;
background: url(https://upload.wikimedia.org/wikipedia/commons/thumb/f/f1/S%C3%A4ugende_H%C3%BCndin.JPG/800px-S%C3%A4ugende_H%C3%BCndin.JPG) no-repeat center center;
background-size: contain;
}
<div class="wrapper">
</div>
try this
vertical
.picture {
position: relative;
height: 100%;
width: auto;
margin: auto;
left: 0;
right: 0;
background-position: center;
}
horizontal
.picture {
position: relative;
width: 100%;
height: auto;
margin: auto;
left: 0;
right: 0;
background-position: center;
}
jsfiddle horizontal case
jsfiddle vertical case
please add height property auto and image width in percentage %, in this property you can manage aspect ratio,
width:50%,
height:auto,

Thank in advance.
The .home div needs to be absolutely positioned in order not to "push" the background div downwards. The background div shouldn't have the fullscreen-img class, since most of those rules should be removed. It only needs height: 100% because divs have width: 100% by default since they're block elements. Of course, move the inline styles into a class or ID rules, I left them there just to show you.
That's all you need basically:
remove the .fullscreen-img class from the background div
set its height to 100% instead
make the .home div absolutely positioned
