I want a particular picture to cover the entire background of my site and when the window is resized, I want the picture to be scaled accordingly. What I'm looking for is something like https://www.tumblr.com. Notice the picture in the background scales accordingly to the window size.
Here is my css:
html, body {
height: 100%;
width: 100%;
padding: 0;
margin: 0;
}
#backdrop {
z-index: -999;
min-height: 100%;
min-width: 100%;
width: 100%;
height: auto;
position: fixed;
top: 0;
left: 0;
}
Where #backdrop is the id for the image I'm using.
I've tried numerous things but nothing seems to change the way my image is displayed.
Use object-fit to let an img behave like a background-image. See this working example:
html, body {
height:100%;
margin:0;
padding:0;
}
img {
position: fixed;
top: 0;
left: 0;
width: 100%;
height: 100%;
object-fit: cover;
}
<img src="http://lorempixel.com/g/1100/300">
Two things:
Change the height: auto; to height: 100%, and add background styles.
#backdrop {
z-index: -999;
min-height: 100%;
min-width: 100%;
width: 100%;
height: 100%;
position: fixed;
top: 0;
left: 0;
background: url("image.jpg") center center no-repeat;
background-size: cover;
}
Also, use a HTML 5 Doctype:
<!DOCTYPE html>

How can i fit this video on the whole screen?
I have used the below code
<style>
*{
margin: 0px;
padding: 0px;
}
#sky-video{
position: fixed;
width: 100%;
height: 100%;
z-index: -100;
}
</style>
<body>
<video src="videos/Sky.mp4" autoplay muted loop id="sky-video">You brower does not support vidoes</video>
</body>
Here you can see there is a gap in right and left of the video.
Is this because the video size is too small to fit in the whole screen?
You may also want to add: object-fit
#sky-video {
position: fixed;
width: 100%;
height: 100%;
z-index: -100;
object-fit: cover;
}
You need to set the width and height for the video container first.
Your container now is then:
body {
display: block;
width: 100%;
height: 100vh;
position: relative;
}
body #sky-video {
width: 100%;
height: auto;
object-fit: cover;
}
I'm using the following code to show a background image on my page:
#bg-pic {
top: 0px;
left: 0px;
position: fixed;
z-index: -1;
margin: 0px;
width: 100%;
}
#bg-pic > img {
width: 100%;
display: block;
}
<div id="bg-pic">
<img src="https://images.pexels.com/photos/259915/pexels-photo-259915.jpeg" />
</div>
This works fine once the ratio of the browser window is wide enough. But in case I have a very small window I want the picture still to cover the page so instead of width: 100%; height: 100%; would be correct. How can I fix this?
EDIT: Since the provided answer don't solve my actual problem let's describe it using an example:
Let's assume my picture has dimensions 100x100 and my browser window has dimensions 200x100. Then only the upper 100 pixels are filled with the picture. What I want is that the whole browser window is filled by zooming into the picture (of course then the area on the right and on the left of the picture which corresponds to the right 25 and left 25 pixels of the picture is omitted).
Use the background property instead of an img element.
Demo:
body {
background: url('image.jpg') center center / cover;
}
jsfiddle
In your case:
html, body {
min-height: 100%;
}
body {
margin: 0;
background: url('bg.jpg') center center / cover;
}
You could use the object-fit and object-position properties on the image tag.
Codepen example
#bg-pic{
top:0px;
left:0px;
position: fixed;
opacity: 0.18;
z-index: -1;
margin: 0px;
width: 100%;
height:100%;
}
#bg-pic img {
object-fit: cover;
object-position: 50% 50%;
width: 100%;
height: 100%;
}
You can read more about object-fit at CSS-Tricks : https://css-tricks.com/on-object-fit-and-object-position/
You just have to add height:100vh; in your img style tag,
You can't use height:100% because it won't be applied unless you have specified static height to parent div.
Always a better option to go for vh dimension.
#bg-pic {
top: 0px;
left: 0px;
position: fixed;
z-index: -1;
margin: 0px;
width: 100%;
}
<div id="bg-pic">
<img src="https://images.pexels.com/photos/259915/pexels-photo-259915.jpeg" style="width:100%; height:100vh; display: block;"/>
</div>
body { background-image:url("../images/bg.jpg");
background-repeat: no-repeat;
background-size: 100% 100%; }
Try this
You can try flexbox like this:
#bg-pic {
top: 0;
left: 0;
position: fixed;
opacity: 0.5;
z-index: -1;
width: 100%;
height: 100%;
display: flex;
align-items: flex-start;
justify-content: center;
}
img {
min-width: 100%;
min-height: 100%;
flex-shrink: 0;
}
<div id="bg-pic"><img src="https://picsum.photos/800/800?image=1069" style="" /></div>
Try this, its cross browser compatible:
div {
position:relative;
}
img {
max-height: 100%;
max-width: 100%;
margin: auto;
position: absolute;
top: 0;
left: 0;
bottom: 0;
right: 0;
}
This assumes you have given a size to the div.
You might be looking for background-size: contain. Paired with height: 100vh should give you desired effect.
If you need the image centered horizontally you can add background-position: 50% 0% or background-position: center; for both horizontal and vertical centering.
#container-with-background {
background: url(https://images.pexels.com/photos/259915/pexels-photo-259915.jpeg);
background-repeat: no-repeat;
background-size: contain;
height: 100vh;
}
<div id="container-with-background">
</div>
If you need your images to be inside your <img> tags you can achieve the same effect with max-width: 100% and max-height: 100% on the <img> tag, and fixed height on the container - height: 500px for example. Setting the height to 100vh will make it fullscreen.
#container {
height: 100vh; /* Can be set to fixed value if needed */
}
img {
display: block;
margin: 0 auto;
max-width: 100%;
max-height: 100%;
}
<div id="container">
<img src="https://images.pexels.com/photos/259915/pexels-photo-259915.jpeg">
</div>
I am using this code. It covers the whole background with 1 image. The problem is the upper part of it, which gets cut by browser and the lower part by the taskbar. As i go fullscreen it works fine. I want the image to sit in the browser fully. Is there any method available for that??
#bg {
position: fixed;
top: -50%;
left: -50%;
width: 200%;
height: 200%;
}
#bg img {
position: absolute;
top: 0;
left: 0;
right: 0;
bottom: 0;
margin: auto;
min-width: 50%;
min-height: 50%;
}
<div id="bg">
<img src="images/bg.jpg" alt="">
</div>
You can change your current CSS to:
#bg {
position: fixed;
width: 100%;
height: 100%;
}
#bg img {
position: absolute;
/* display: cover; */
right: 0;
bottom: 0;
min-width: 100%;
min-height: 100%;
}
Here is example 1.
Alternatively, load the image purely with CSS and set it as background. Change your code to:
HTML
<div id="bg">
</div>
CSS
#bg {
position: fixed;
width: 100%;
height: 100%;
background: url(images/bg.jpg);
top: 0;
left: 0;
}
Here is example 2.
Both of them will set the image as background.
Change 1
Remove the
top: -50%;
left: -50%;
on your code. It makes the hiding of both you mentioned.
Change 2
You need to declare the image width and height in the
#bg img{
width:100%;
height:100%;
}
I have a div with background image put inside another div, instead of fit width parent div, it fit full screen. Please take a look my code to know clearly, sorry for bad english.

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

width: 1230px;
I have a cover Image in an html page that is wrapped by a div.
The div size is always width:100% height:33%.
I want any arbitrary image to scale to fill without be stretched on any screen size and ratio.
My CSS looks like this:
.headerImageWrapper{
position: relative;
width: 100%;
height: 33%;
overflow:hidden;
}
.coverImageCentered{
min-width: 100%;
min-height: 100%;
position: absolute;
top: -9999px;
bottom: -9999px;
left: -9999px;
right: -9999px;
margin: auto;
}
My problem is that the image size is not the mimimum possible that satisfy these conditions.
See the image to understand better
I'm an iOS developer, if you now how it works basically like the contentMode : scale aspect to fill
This is what you looking for.. you can test this solution on the device

html, body {

overflow: hidden;
}
.bgd-cover {

min-width: 50%;
min-height: 13%;
}
UPD: i updated my answer
UPD2:
I don't know if I get right your question, but you may try to experiment with background-size: cover (you won't need wrapper with this one).
