Center Bootstrap Carousel images when window is resized - html

I have seen a lot of similar questions, but the solutions did not apply.
I am trying to make a Bootstrap carousel such that when the window is resized, the image remains centered while also maintaining the required image height and minimum 100% width properties.
This is a little difficult to explain, but you can see a similar concept on http://www.lyft.com
I have replicated a similar issue on codepen which you can see, that if you shrink the window down to the size of a mobile device the image remains fixed and ultimately you're looking at the top left corner of the image (usually clouds or some unrecognizable blur).
I'm trying to have this image move left and remain centered as the horizontal view shrinks so that the image remains relevant.
My additional carousel styles:
/* CUSTOMIZE THE CAROUSEL
-------------------------------------------------- */
/* Carousel base class */
.carousel {
height: 500px;
margin-bottom: 60px;
overflow: hidden;
}
/* Since positioning the image, we need to help out the caption */
.carousel-caption {
z-index: 10;
}
/* Declare heights because of positioning of img element */
.carousel .item {
height: 500px;
background-color: #777;
}
.carousel-inner > .item > img {
position: relative;
top: 0;
left: 0;
min-width: 100%;
max-width: none;
height: auto;
}
.carousel-inner img{
margin: auto;
}
#mycarousel{
position: relative;
top: 0;
}
And the simple carousel:
<div id="mycarousel" class="carousel slide" data-ride="carousel">
<!-- Indicators -->
<ol class="carousel-indicators">
<li data-target="#mycarousel" data-slide-to="0" class="active"></li>
<li data-target="#mycarousel" data-slide-to="1"></li>
<li data-target="#mycarousel" data-slide-to="2"></li>
<li data-target="#mycarousel" data-slide-to="3"></li>
<li data-target="#mycarousel" data-slide-to="4"></li>
</ol>
<!-- Wrapper for slides -->
<div class="carousel-inner" role="listbox">
<div class="item active">
<img src="https://unsplash.it/2000/1250?image=397" data-color="lightblue" alt="First Image">
</div>
<div class="item">
<img src="https://unsplash.it/2000/1250?image=689" data-color="firebrick" alt="Second Image">
</div>
<div class="item">
<img src="https://unsplash.it/2000/1250?image=675" data-color="violet" alt="Third Image">
</div>
<div class="item">
<img src="https://unsplash.it/2000/1250?image=658" data-color="lightgreen" alt="Fourth Image">
</div>
<div class="item">
<img src="https://unsplash.it/2000/1250?image=638" data-color="tomato" alt="Fifth Image">
</div>
</div>
</div>

I made a solution based on the lyft site you linked in your post. I turned your img into div and used a background image then styled appropriately.
<div class="carousel-inner" role="listbox">
<div class="item active">
<div class="item-child" style="background-image: url('https://unsplash.it/2000/1250?image=397');" data-color="lightblue" alt="First Image"></div>
</div>
<div class="item">
<div class="item-child" style="background-image: url('https://unsplash.it/2000/1250?image=689');" data-color="firebrick" alt="Second Image"></div>
</div>
<div class="item">
<div class="item-child" style="background-image: url('https://unsplash.it/2000/1250?image=675');" data-color="violet" alt="Third Image"></div>
</div>
<div class="item">
<div class="item-child" style="background-image: url('https://unsplash.it/2000/1250?image=658');" data-color="lightgreen" alt="Fourth Image"></div>
</div>
<div class="item">
<div class="item-child" style="background-image: url('https://unsplash.it/2000/1250?image=638');" data-color="tomato" alt="Fifth Image"></div>
</div>
Then removed this .carousel-inner > .item > img and added this CSS:
.carousel-inner .item .item-child {
background-position: top center;
background-size: cover;
position: absolute;
bottom:0;
top: 0;
left: 0;
right:0;
width: 100%;
height: auto;
}
You can see the js.fiddle here if you want to play around with it. Hope that helps.

There you go, Easiest fix
instead of min-width use width on images
.carousel-inner > .item > img {
position: relative;
top: 0;
left: 0;
width: 100%;
max-width: none;
height: auto;
}
also throw in a height adjustment for carousel like this
.carousel .item {
height: auto;
background-color: #777;
}

How to always have slide image centered?

current state of my carousel
I'm trying to code the slide carousel of my website, so no matter what image I upload for the slides, images will always be centered no matter what(currently only centers image if it is a specific resolution).
I have tried calling the class in CSS and centering the margin that way, but its still not working. Here is my code so far:
I called specific slide item class in CSS, updated margin, image still not centered.
.carousel-control.left,
.carousel-control.right {
background-image: none;
}
.carousel-control>.fa {
font-size: 40px;
position: absolute;
top: 50%;
z-index: 5;
display: inline-block;
margin-top: -20px;
}
.item {
margin: 0px auto; // center
width: 1100px;
height: 500px;
text-align: center;
}
<div id="carousel-example-generic" class="carousel slide" data-ride="carousel">
<ol class="carousel-indicators">
<li data-target="#carousel-example-generic" data-slide-to="0" class="active"></li>
<li data-target="#carousel-example-generic" data-slide-to="1" class=""></li>
<li data-target="#carousel-example-generic" data-slide-to="2" class=""></li>
</ol>
<div class="carousel-inner">
<div class="item active">
<img src="https://thumbs.gfycat.com/ShallowRawCockatoo-size_restricted.gif" alt="First slide" text-align="center">
</div>
<div class="item">
<img src="https://thumbs.gfycat.com/ShallowRawCockatoo-size_restricted.gif" alt="Second slide" text-align="center">
</div>
<div class="item">
<img src="https://thumbs.gfycat.com/ShallowRawCockatoo-size_restricted.gif" alt="Third slide" text-align="center">
</div>
</div>
<a class="left carousel-control" href="#carousel-example-generic" data-slide="prev">
<span class="fa fa-angle-left"></span>
</a>
<a class="right carousel-control" href="#carousel-example-generic" data-slide="next">
<span class="fa fa-angle-right"></span>
</a>
</div>
First of all, you have an invalid CSS comment, that might cause some trouble as well, the right way to comment in CSS is using /* comment */
Next, lets take a look at your attemp of centering things
.item {
margin: 0px auto; /* center */
width: 1100px;
height: 500px;
text-align: center;
}
In theory, this would work, but we need to know what we are centering, which is in this case the whole slide, not its contents (which you probably want to center)
So the quickest solutions here might be the following
.item img {
margin: 0 auto;
}
This is the same way as you tried, but applied on the correct element that needs to be centered -> the content of your slide.
More 'robust' way of centering would be setting your slide to display: flex and using flexbox to center your stuff.
Try it this way
.item {
width: 1100px;
height: 500px;
display: flex;
justify-content: center; /* horizontal centering */
align-items: center; /* vertical centering */
}
Try those out and let me know!

Resizing Image inside carousel

I created a carousel with images inside. But one of the images appear to be very big while the other is blur but fits well. I tried resizing with CSS but it's not working. What should I do?
Here is what I mean
This First screenshot shows the image fits wellshows image fits well
while in this screenshot, the image is big and it is cut off from the carousel
shows image is cut off from carousel
Here is what I tried
<style type="text/css">
.wrapper{
font-family: Nunito;
background-repeat: no-repeat;
height: 100%;
background-position: center;
background-size: cover;
overflow: hidden;

margin: 0 auto;
}
.carousel-inner {
width: auto;
height: 370px;
max-height: 370px !important;
position: relative;
}
.carousel img {
position: relative;
top: 0;
min-width: 100%;
height: auto;
max-width: 100%;
}
</style>

</a>
<a class="carousel-control-next" href="#carouselExampleIndicators" role="button" data-slide="next">
<span class="carousel-control-next-icon" aria-hidden="true"></span>
<span class="sr-only">Next</span>
</a>
</div>
You are setting the width of 2 images to be 100% of the parent, and the reason it is being cut off is .wrapper class has a style of overflow: hidden, so your images are sizing properly but the overflow is hidden.
See example: https://imgur.com/a/D5Pfw0S
If you want to retain this fixed height, add styling for the .img1 and .img2 classes (Or create 1 img wrapper class which I world recommend more) and define the height on those, that way you can give the img elements a height of 100%, and set the width to be the variable (auto).
.img1, .img2 {
height: 370px;
max-height: 370px !important;
}
/* Or do this and add the class in place of img1 and img2 */
.img-wrapper {
height: 370px;
max-height: 370px !important;
}
.carousel img {
position: relative;
top: 0;
width: auto;
height: 100%;
}
I would however recommend editing your images to be a uniform size. That way there is no major disparities in the design.

How to fit fit carousel images? (HTML/CSS/Bootstrap4)

I'm new in HTML, CSS, and Bootstrap and I'm trying to create a carousel for my page.
The carousel is working, but the images are not fitting to the page. The size is too big (height and width) and I'm trying to fit but it's not working properly.
My codes are:
.carousel-inner img{
width:100%;
height: 40%;
}
.carousel-caption {
position: absolute;
top: 60%;
transform: translateY(-60%);
}
.carousel-caption h1{
font-size:470%;
text-transform: uppercase;
text-shadow:3px 3px 15px #000;
}
.carousel-caption h3{
color: #ffc107;
font-size: 200%;
font-weight: 500;
text-shadow: 3px 3px 10px #000;
padding-botton: 1rem;
}
<!-- Image slider -->
<div id="slides" class="carousel slide" data-ride="carousel">
<ul class= "carousel-indicators">
<li data-target= "#slides" data-slide-to= "0" class="active"></li>
<li data-target= "#slides" data-slide-to= "1"></li>
<li data-target= "#slides" data-slide-to= "2"></li>
</ul>
<div class="carousel-inner">
<div class="carousel-item active">
<img src="/home/susy/Desktop/GIT/vegan-/imagens/feijuca6.jpg">
<div class="carousel-caption">
<h1 class="display-2"> Have you ever tried?</h1>
<h3> Discover the authentic flavour</h3>
<br>
<button type="button" class= "btn btn-outline-light btn-lg"> Click Here</button>
</div>
</div>
<div class="carousel-item">
<img src="/home/susy/Desktop/GIT/vegan-/imagens/pudim.jpg">
</div>
<div class="carousel-item">
<img src="/home/susy/Desktop/GIT/vegan-/imagens/meal.jpg">
</div>
</div>
The first is the CSS (I'm using CSS 3) and the second is the HTML. I'm also using Bootstrap 4.
Does anyone know what am I missing or doing wrong? Or how can I change the sizes to fit the carousel? Please.
As per my knowledge use
.carousel-inner img{
max-width:100%;
height: auto;
display: block;
}
instead of using
.carousel-inner img{
width:100%;
height: 40%;
}
if you want absolute height you can specify height : 300px
.carousel-inner img{
max-width:100%;
height: 300px;
object-fit: cover;
object-position: center;
}
What I think you are searching for is adding class="d-block w-100" in your image tag.

how to remove extra padding covered with carousel controls

Here , I have tried to even give margin:0,padding:0, but still there is some margin on left and right side ,so should I remove or add anything to make it work? I have even tried to remove margin from every component using * . But still it did not give me the same effect.
As you're using Bootstrap, the .container class has padding-left: 15px & padding-right: 15px styles.
Just set padding: 0 to your .container class and it's all done.
However, be careful that in the screenshot below, you can see that bootstrap is loaded after your css. So if you just add padding: 0 to your .container class it will be overrided by bootstrap's.
Try changing the order of stylesheets loading in your <head> so
yours is loaded last.
Or just put a style attribute with padding: 0 directly to your container <div>, but that's not best practice.
Result:
Take a look at your CSS, you have paddings in your .container class located at https://maxcdn.bootstrapcdn.com/bootstrap/3.3.7/css/bootstrap.min.css, precisely
.container{
padding-right: 15px;
padding-left: 15px;
margin-right: auto;
margin-left: auto;
}
Just workaround those lines by overriding them if you really need to use Bootstrap.
Another solution is to use a local instance of that CSS code but customized by you, so just save the CSS file, remove those lines and use that CSS locally.

twitter-bootstrap center carousel image reguardless of screen size

I have the following desires for a twitter bootstrap carousel:
When screen is bigger then carousel, I want the image centered.
When the screen is smaller than the carousel, I want to see just PART of the image. This part of the image should be centered.
At no point should the images be resized or scaled
The transitions should work.
My example below fixed problems 1-3.. but it breaks 4. I can easily fix 4 if I am willing to break 3, but that is no good.

This might help if you want the image to be re-sized according to the screen size of the device. The width = "100%" will do the job.
<img src="http://lorempixel.com/1200/600/abstract/2" width = "100%">
just add this to your css:
.carousel-inner > .item > img, .carousel-inner > .item > a > img {
width: 100%;
}
add this
.carousel .item img {
left: -9999px; /*important */
right: -9999px; /*important */
margin: 0 auto; /*important */
max-width: none; /*important */
min-width: 100%;
position: absolute;
}
And of course one of the parent divs needs to have a position:relative, but I believe it does by default.
