I have a page where only form exists and I want form to be placed in the center of the screen.
<div class="container">
<div class="row justify-content-center align-items-center">
<form>
<div class="form-group">
<label for="formGroupExampleInput">Example label</label>
<input type="text" class="form-control" id="formGroupExampleInput" placeholder="Example input">
</div>
<div class="form-group">
<label for="formGroupExampleInput2">Another label</label>
<input type="text" class="form-control" id="formGroupExampleInput2" placeholder="Another input">
</div>
</form>
</div>
</div>
The justify-content-center
aligns the form horizontally, but I can't figure out how to align it vertically. I have tried to use align-items-center
and align-self-center
, but it doesn't work.
What am I missing?

flexbox can help you. info here
<div class="d-flex flex-row justify-content-center align-items-center" style="height: 100px;">
<div class="p-2">

<div class="p-2">

been going thru a lot of posts on getting a form centered in the page and none of them worked. code below is from a react component using bootstrap 4.1. height should be 100vh and not 100%
<div className="container">
<div className="d-flex justify-content-center align-items-center" style={height}>
<form>
<div className="form-group">
<input className="form-control form-control-lg" placeholder="Email" type="email"/>
</div>
<div className="form-group">
<input className="form-control form-control-lg" placeholder="Password" type="password"/>
</div>
<div className="form-group">
<button className="btn btn-info btn-lg btn-block">Sign In</button>
</div>
</form>
</div>
</div>
where height in style is:
const height = { height: '100vh' }
None has worked for me. But his one did.
Since the Bootstrap 4 .row class is now display:flex you can simply use the new align-self-center flexbox utility on any column to vertically center it:
<div class="row">
<div class="col-6 align-self-center">
<div class="card card-block">
Center
</div>
</div>
<div class="col-6">
<div class="card card-inverse card-danger">
Taller
</div>
</div>
</div>
I learned about it from https://medium.com/wdstack/bootstrap-4-vertical-center-1211448a2eff
This is working in IE 11 with Bootstrap 4.3. While the other answers were not working in IE11 in my case.
<div class="row mx-auto justify-content-center align-items-center flex-column ">
<div class="col-6">Something </div>
</div>

This work for me:
<section class="h-100">
<header class="container h-100">
<div class="d-flex align-items-center justify-content-center h-100">
<div class="d-flex flex-column">
<h1 class="text align-self-center p-2">item 1</h1>
<h4 class="text align-self-center p-2">item 2</h4>
<button class="btn btn-danger align-self-center p-2" type="button" name="button">item 3</button>
</div>
</div>
</header>
</section>
I am required to show form vertically center inside container-fluid so I developed my own code for the same.
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<meta name="viewport" content="width=device-width, initial-scale=1.0">
<title>Document</title>
<link rel="stylesheet" type="text/css" href="css/bootstrap.min.css">
<style>
.container-fluid
{
display: table-cell;
height: 100vh;
width: 100vw !important;
vertical-align: middle;
border:1px solid black;
}
</style>
</head>
<body>
<div class="container-fluid">
<div class="row">
<div class="col-8 offset-2">
<div class="card shadow">
<div class="card-header bg-danger text-white">
<h2>Login</h2>
</div>
<div class="card-body">
<form action="">
<div class="form-group row">
<label for="txtemail" class="col-form-label col-sm-2">Email</label>
<div class="col-sm-10">
<input type="email" name="txtemail" id="txtemail" class="form-control" required />
</div>
</div>
<div class="form-group row">
<label for="txtpassword" class="col-form-label col-sm-2">Password</label>
<div class="col-sm-10">
<input type="password" name="txtpassword" id="txtpassword" class="form-control"
required />
</div>
</div>
<div class="form-group">
<button class="btn btn-danger btn-block">Login</button>
<button class="btn btn-warning btn-block">clear all</button>
</div>
</form>
</div>
</div>
</div>
</div>
<script src="js/jquery.js"></script>
<script src="js/popper.min.js"></script>
<script src="js/bootstrap.min.js"></script>
</body>
</html>
Use This Code In CSS :
.container {
width: 600px;
height: 350px;
position: absolute;
top: 50%;
left: 50%;
transform: translate(-50%, -50%);
display: inline-flex;
}
From the doc (bootsrap 4):
https://getbootstrap.com/docs/4.0/utilities/flex/#justify-content
.justify-content-start
.justify-content-end
.justify-content-center

I ended up here because I was having an issue with Bootstrap 4 grid system and an Angular *ngFor loop. I fixed it by applying a col justify-content-center class to the div implementing the ngFor:
<div class="row" style="border:1px solid red;">
<div class="col d-flex justify-content-center">
<button mat-raised-button>text</button>
</div>
<div *ngFor="let text of buttonText" class="col d-flex justify-content-center">
<button mat-raised-button>text</button>
</div>
</div>
You need something to center your form into. But because you didn't specify a height for your html and body, it would just wrap content - and not the viewport. In other words, there was no room where to center the item in.
html, body {
height: 100%;
}
.container, .row.justify-content-center.align-items-center {
height: 100%;
min-height: 100%;
}
Bootstrap has text-center to center a text. For example
<div class="container text-center">
You change the following
<div class="row justify-content-center align-items-center">
to the following
<div class="row text-center">
