How can I center a div vertically in bootstrap 5?
It should be aligned in the middle between of content before the div and the screen end.
Tried this:
<div>some content</div>
<div class="d-flex flex-column min-vh-100 justify-content-center align-items-center">
<div>div that should be centered</div>
</div>
It makes the pages longer than it actually is. The div doesn´t looks centered.
You can do it like this:
Wrap everything with one div that has 100% screen width and height.
Use flex-grow-1 for the second div so it takes the remaining height and center everything inside.

Here's how it looks now
Adding a div to cover <input> and <form> with the class d-flex, adding padding or margin to customize the space between textbox and button. For example, I added ms-4 to the button div.

I'm trying to create a website using bootstrap where the title and the search bar is at the center of the screen. I tried adding the my-auto, but that doesn't do anything. It shouldn't be difficult, but I can't make it work. Any ideas?

You can use display:flex; property to center the content.
.container{
display: flex;
flex-direction:column;
align-items: center;
justify-content: center;
text-align: center;
}
<div class="container" style="margin-top: 8%;">
<div class="col-md-6 col-md-offset-3">
<div class="row">
<div id="logo" class="text-center">
<h1>Movie</h1>

<div class="input-group">
<input id="1" class="form-control" type="text" name="search" placeholder="Search..." required/>
<span class="input-group-btn">
<button type="button" class="btn btn-outline-primary">search</button>
<i class="glyphicon glyphicon-search" aria-hidden="true"></i>
</span>
</div>
</div>
</form>
</div>
</div>
<p>movie!</p>
</div>
What youre looking for is flex box,
Try adding to the <div class="row"> the style of
display: flex;
flex-direction: column;
align-items: center;
I'm working on a responsive web app in Bootstrap 4 and use cards with images on one of the pages. Everything works fine through any window resizing on a desktop view; however, when I view them on mobile the card image height is completely off and about half the size of what it should be.
Here's the HTML:
<div class="container">
<header class="jumbotron">
<div class="container">
<h1>By The Numbers.</h1>
<p>View our growing database:</p>
<p>
<a class="btn btn-primary btn-large" href="/players/new">Add New Player</a>
</p>
<p>
<form action="/players" method="GET" class="form-inline">
<div class="form-group">
<input type="text" name="search" placeholder="Player Search..." class="form-control">
<input type="submit" value="Search" class="btn btn-default">
</div>
</form>
</p>
</div>
</header>
<div class="row text-center">
<div class="col-lg-3 col-md-4 col-sm-6 mb-4">
<div class="card">
<img src="https://t3.ftcdn.net/jpg/02/12/43/28/240_F_212432820_Zf6CaVMwOXFIylDOEDqNqzURaYa7CHHc.jpg" id="playerCardImage" class="card-img-top" alt="Name">
<div class="card-body">
<h5 class="card-title">Name</h5>
<h5 class="card-title">Detail</h5>
More Info
</div>
</div>
</div>
</div>
The below CSS was added to ensure the cards all remain the same height, but this seems to cause the issue where the image is extremely small on mobile.
CSS:
#playerCardImage {
width: 100%;
height: 15vh;
object-fit: cover;
}
A codepen with the card example can be found here: https://codepen.io/franchise/pen/MWaoXOp.
Detail:
Cannot replicate sizing issue with Chrome Dev Tools mobile view, it only shows what I would expect the card to look like on mobile
To recreate the issue, view the Codepen on mobile to see the image is about half of the size compared to viewing the Codepen on a desktop
What am I missing here? Thanks in advance for the help.
Instead of creating a style based on id, can try to create the style based on class card-img-top.
.card-img-top {
width: 100%;
height: 150px;
object-fit: cover;
}

You should use height in percent
#playerCardImage {
width: 100%;
object-fit: cover;
}
#media all and (max-width:768px){
#playerCardImage {
width: 100%;
height: 110px;
object-fit: cover;
}
}

I have the folowing code that renders different from what I was expecting when you add the form tag.
Try removing the form tags to see the difference.

With form tag
Without form tag
I want it to look like the second picture, but dont know why the form tag changes the alignment.
Your form tag should has a col-sm-12 class
<form action="" class="col-sm-12">
...
</form>
Change your form code with following code :
<form action="" class="col-sm-12">
<div class="row">
<div class="form-group col-md-12">
<div class="input-group mb-3">
<div class="input-group-prepend">
<span class="input-group-text" id="basic-addon1"><i class="fas fa-link"></i></span>
</div>
<input type="text" class="form-control" placeholder="Upload File">
<div class="input-group-append">
<button class="btn btn-success">Guardar</button>
</div>
</div>
</div>
</div>
</form>
Align it and you should use col class only inside row class.

use this class to make the image responsive in bootstrap 4 class="img-fluid"
if the image is very small in width and still you want to make it to fit the grid then give image width 100%, you can use this class too "w-100" in BS4
have a look on my fiddle and tell me if that's why you are looking for.
<div class="container">

img-fluid is the answer you are looking for. As a side note, as of Bootstrap 4, there is no reason to use "col-sm col-md col-lg col-xl" etc, just use col- and it will adjust to the screen size automatically.
