Bootstrap Center Vertical and Horizontal Alignment

Closed last year.
I am trying to center my Container in the middle of the page using Bootstrap 4. I have been unsuccessful thus far. Any help would be appreciated.
I have built it at Codepen.io so you guys can play with it and let me know what works as I am about out of ideas...

var currentQuote = "";
function randomQuote() {

$("#quote-author").html('<p id="quote-author" class="lead"><em>' + response.quoteAuthor + '</em></p>');
currentAuthor = response.quoteAuthor;
currentQuote = response.quoteText
}
});
}

Important! Vertical center is relative to the height of the parent
If the parent of the element you're trying to center has no defined
height, none of the vertical centering solutions will work!
Now, onto vertical centering...
Bootstrap 5 (Updated 2021)
Bootstrap 5 is still flexbox based so vertical centering works the same way as Bootstrap 4. For example, align-items-center, justify-content-center or auto margins can used on the flexbox parent (row or d-flex).
use align-items-center on a flexbox row parent (row or d-flex)
use justify-content-center on a flexbox column parent (d-flex flex-column)
use my-auto on a flexbox parent
Vertical Center in Bootstrap 5
Bootstrap 4
You can use the new flexbox & size utilities to make the container full-height and display: flex. These options don't require extra CSS (except that the height of the container (ie:html,body) must be 100%).
Option 1 align-self-center on flexbox child
<div class="container d-flex h-100">
<div class="row justify-content-center align-self-center">
I'm vertically centered
</div>
</div>
https://codeply.com/go/fFqaDe5Oey
Option 2 align-items-center on flexbox parent (.row is display:flex; flex-direction:row)
<div class="container h-100">
<div class="row align-items-center h-100">
<div class="col-6 mx-auto">
<div class="jumbotron">
I'm vertically centered
</div>
</div>
</div>
</div>
https://codeply.com/go/BumdFnmLuk
Option 3 justify-content-center on flexbox parent (.card is display:flex;flex-direction:column)
<div class="container h-100">
<div class="row align-items-center h-100">
<div class="col-6 mx-auto">
<div class="card h-100 border-primary justify-content-center">

More on Bootstrap 4 Vertical Centering
Now that Bootstrap 4 offers flexbox and other utilities, there are many approaches to vertical
alignment. http://www.codeply.com/go/WG15ZWC4lf
1 - Vertical Center Using Auto Margins:
Another way to vertically center is to use my-auto. This will center the element within it's container. For example, h-100 makes the row full height, and my-auto will vertically center the col-sm-12 column.
<div class="row h-100">
<div class="col-sm-12 my-auto">
<div class="card card-block w-25">Card</div>
</div>
</div>
Vertical Center Using Auto Margins Demo
my-auto represents margins on the vertical y-axis and is equivalent to:
margin-top: auto;
margin-bottom: auto;
2 - Vertical Center with Flexbox:
Since Bootstrap 4 .row is now display:flex you can simply use align-self-center 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>
or, use align-items-center on the entire .row to vertically center align all col-* in the row...
<div class="row align-items-center">
<div class="col-6">
<div class="card card-block">
Center
</div>
</div>
<div class="col-6">
<div class="card card-inverse card-danger">
Taller
</div>
</div>
</div>
Vertical Center Different Height Columns Demo
See this Q/A to center, but maintain equal height
3 - Vertical Center Using Display Utils:
Bootstrap 4 has display utils that can be used for display:table, display:table-cell, display:inline, etc.. These can be used with the vertical alignment utils to align inline, inline-block or table cell elements.
<div class="row h-50">
<div class="col-sm-12 h-100 d-table">
<div class="card card-block d-table-cell align-middle">
I am centered vertically
</div>
</div>
</div>

Important! Did I mention height?
Remember vertical centering is relative to the height of the parent element. If you want to center on the entire page, in most cases, this should be your CSS...
body,html {
height: 100%;
}
Or use min-height: 100vh (min-vh-100 in Bootstrap 4.1+) on the parent/container. If you want to center a child element inside the parent. The parent must have a defined height.
Also see:
Vertical alignment in bootstrap 4
Bootstrap Center Vertical and Horizontal Alignment
you can vertically align your container by making the parent container flex and adding align-items:center:
body {
display:flex;
align-items:center;
}
Updated Pen
Using bootstrap version 5 or later, use the code below to center the content horizontally and vertically.
<div class="vh-100 d-flex justify-content-center align-items-center">
<h1>Centered horizontally and vertically!</h1>
</div>
Following bootstrap 4 classes helped me solve this
<div class="col text-center justify-content-center align-self-center">
<img width=3rem src=".." alt="...">
</div>
Because none of the above worked for me, I am adding another answer.
Goal: To vertically and horizontally align a div on a page using bootstrap 4 flexbox classes.
Step 1: Set your outermost div to a height of 100vh. This sets the height to 100% of the Veiwport Height. If you don't do this, nothing else will work. Setting it to a height of 100% is only relative to the parent, so if the parent is not the full height of the viewport, nothing will work. In the example below, I set the Body to 100vh.
Step 2: Set the container div to be the flexbox container with the d-flex class.
Step 3: Center div horizontally with the justify-content-center class.
Step 4: Center div vertically with the align-items-center
Step 5: Run page, view your vertically and horizontally centered div.
Note that there is no special class that needs to be set on the centered div itself (the child div)
<body style="background-color:#f2f2f2; height:100vh;">
<div class="h-100 d-flex justify-content-center align-items-center">
<div style="height:600px; background-color:white; width:600px;">
</div>
</div>
</body>
I did it this way with Bootstrap 4.3.1:
<div class="d-flex vh-100">
<div class="d-flex w-100 justify-content-center align-self-center">
I'm in the middle
</div>
</div>
.jumbotron {
position: relative;
top: 50%;
transform: translateY(-50%);
}
<div class="row">
<div class="col-md-6">
<img src="/assets/images/ebook2.png" alt="" class="img-fluid">
</div>
<div class="col-md-6 my-auto">
<h3>Heading</h3>
<p>Some text.</p>
</div>
</div>
This line is where the magic happens <div class="col-md-6 my-auto">, the my-auto will center the content of the column. This works great with situations like the code sample above where you might have a variable sized image and need to have the text in the column to the right line up with it.
I've tried all the answers herefrom, but found out here is the difference between h-100 and vh-100
Here is my solution:
<div className='container vh-100 d-flex align-items-center col justify-content-center'>
<div className="">
...
</div>
</div >
<div class="col-lg-5 col-sm-5 offset-1 d-flex">
<div class="offer-txt justify-content-center align-self-center">
<span class="inner-title">Our Offer</span>
<h2 class="section-title">Today’s Special </h2>
<p>One morning, when Gregor Samsa woke from troubled dreams, he found himself transformed in his bed into vermin. He lay on his armour-like back, and if he lifted his head a little he could see his brown belly.</p>
</div>

In Bootstrap 4 (beta), use align-middle. Refer to Bootstrap 4 Documentation on Vertical alignment:
Change the alignment of elements with the vertical-alignment
utilities. Please note that vertical-align only affects inline,
inline-block, inline-table, and table cell elements.
Choose from .align-baseline, .align-top, .align-middle, .align-bottom,
.align-text-bottom, and .align-text-top as needed.

Vertical align Using this bootstrap 4 classes:
Method1:
parent: d-table
AND
child: d-table-cell & align-middle & text-center
eg:
<div class="tab-icon-holder d-table bg-light">
<div class="d-table-cell align-middle text-center">
<img src="assets/images/devices/Xl.png" height="30rem">
</div>
</div>
and if you want parent be circle:
<div class="tab-icon-holder d-table bg-light rounded-circle">
<div class="d-table-cell align-middle text-center">
<img src="assets/images/devices/Xl.png" height="30rem">
</div>
</div>
which two custom css classes are as follow:
.tab-icon-holder {
width: 3.5rem;
height: 3.5rem;
}
.rounded-circle {
border-radius: 50% !important
}
Final usage can be like for example:
<div class="col-md-5 mx-auto text-center">
<div class="d-flex justify-content-around">
<div class="tab-icon-holder d-table bg-light rounded-circle">
<div class="d-table-cell align-middle text-center">
<img src="assets/images/devices/Xl.png" height="30rem">
</div>
</div>
<div class="tab-icon-holder d-table bg-light rounded-circle">
<div class="d-table-cell align-middle text-center">
<img src="assets/images/devices/Lg.png" height="30rem">
</div>
</div>
...
</div>
</div>
Method2:
You can use following:
parent: h-100 d-table mx-auto
AND
child: d-table-cell align-middle
Method3:
You can use following:
parent: d-flext align-items-center
also if you want content be center horisontally too:
parent: d-flext align-items-center justify-content-center
bootstrap 5 and blazor web assembly:
<div class="d-flex align-items-center justify-content-center min" style="height: 50vh">
<button class="btn btn-outline-success mx-2">Register</button>
<button class="btn btn-outline-primary mx-2" style="width:123.44px">Login</button></div>
/*You have to add height 100vh */
Center
use .my-auto (bootsrap4) css class on yor div
Place your content within a flexbox container that is 100% high i.e h-100. Then justify the content centrally by using justify-content-center class.
<section class="container h-100 d-flex justify-content-center">
<div class="jumbotron my-auto">
<h1 class="display-3">Hello, Malawi!</h1>
</div>
</section>
in Bootstrap 5 we can do it easily. Below is an example to align card. We just have to set the card width, then the rest setting are using bootstrap 5 class.
<div class="container d-flex vh-100">
<div class="row mx-auto">
<div class="col align-self-center p-4">
<div class="card rounded-3 shadow-sm p-3" style="width:400px">
<div class="card-body">
<h1>I'am centered vertically and horizontally</h1>
</div>
</div>
</div>
</div>
</div>
For all Bootstrap versions 2, 3, 4 and 5 with only two custom classes suitable with any height and width.
.d_tbl{
display:table;
width:100%;
height:200px;
}
.d_tblCel{
vertical-align: middle;
display: table-cell;
text-align: center;

In Bootstrap 4.1.3:
This worked for me when I was trying to center a bootstrap badge inside of a container > row > column next to a h1 title.
What did work was some simple css:
.my-valign-center {
vertical-align: 50%;
}
or
<span class="badge badge-pill" style="vertical-align: 50%;">My Badge</span>

I'm using Bootstrap 5 to try to come up with what I think is a really simple layout. I want to show an MxN grid of cells. Each cell being the same size. I want this to fill the entire viewport without scrollbars in either direction. Scrollbars are where I'm getting stuck.
I've tried different combinations of height and max-height on the various divs. This was helpful on the container div to keep it from growing too tall, but the rows end up overflowing vertically. What I really want is for everything to shrink down to where there are no scrollbars, even if it means the columns get narrower. Ideally I'd like to use bootstrap, but that's not necessarily a requirement.
The below snippet is where I'm at. It seems to be about 20% taller than the viewport.
<link href="https://cdn.jsdelivr.net/npm/bootstrap#5.2.3/dist/css/bootstrap.min.css" rel="stylesheet"/>
<div class="container-fluid">
<div class="row p-0">
<div class="col p-0 border">
<span class="ratio ratio-16x9 d-flex align-items-center justify-content-center">
Cell
</span>
</div>
<div class="col p-0 border">
<span class="ratio ratio-16x9 d-flex align-items-center justify-content-center">
Cell
</span>
</div>
</div>
<div class="row p-0">
<div class="col p-0 border">
<span class="ratio ratio-16x9 d-flex align-items-center justify-content-center">
Cell
</span>
</div>
<div class="col p-0 border">
<span class="ratio ratio-16x9 d-flex align-items-center justify-content-center">
Cell
</span>
</div>
</div>
</div>
Edit 1:
It appears the issue is with aspect-ratio. It seems to want to fill the width even at the expense of growing the height larger than the cell.
Here's an updated example without the ratios. It renders and responds correctly:
<link href="https://cdn.jsdelivr.net/npm/bootstrap#5.2.3/dist/css/bootstrap.min.css" rel="stylesheet"/>
<div class="container-fluid d-flex h-100 mh-100 vh-100 flex-column">
<div class="row p-0 flex-grow-1">
<div class="col p-0 border d-flex align-items-center justify-content-center">
<div>
Cell
</div>
</div>
<div class="col p-0 border d-flex align-items-center justify-content-center">
<div>
Cell
</div>
</div>
</div>
<div class="row p-0 flex-grow-1">
<div class="col p-0 border d-flex align-items-center justify-content-center">
<div>
Cell
</div>
</div>
<div class="col p-0 border d-flex align-items-center justify-content-center">
<div>
Cell
</div>
</div>
</div>
</div>
The ultimate goal would be to get the cell divs to always be at a 16/9 aspect ratio without growing larger than the parent div as well as being centered both horizontally and vertically in the parent. I suppose in other words, the cell divs need to grow until either the height or width reaches the parent and stop there. Instead, it seems to grow until width reaches the parent width, even if the height is taller than the parent.
Also, I should clarify the number of rows/columns is dynamic so that might affect how a solution would work as I wouldn't be able to hard-code any sizing relative to number of rows and columns.
If it helps, the end goal is to have a grid of videos that have to be shown on one screen without scrolling.
Edit 2:
Just for more clarification, here's what I'm expecting in the solution:
No scrollbars anywhere. This is likely to be used in situations where the user can't be expected to scroll.
Needs to work regardless of how many rows/columns I have in the layout, though it's reasonable to assume there will be a small enough number of cells that the content is still easily visible.
Content of each cell will be videos.
All videos need to have the same aspect ratio.
Since it's unlikely that the cell dimensions are going to match video aspect ratio, the video needs to be centered horizontally and vertically in the cell.
User may be resizing the browser, so resizing needs to happen accordingly.
Ideally I'd prefer to stick with bootstrap or straight up css, but will consider other options if this isn't possible.
Not 100% sure if the following is what you are after, but have a look. Note that it uses the CSS4 property aspect-ratio, read more about it here https://developer.mozilla.org/en-US/docs/Web/CSS/aspect-ratio and see browser support here https://caniuse.com/mdn-css_properties_aspect-ratio
I didn't use bootstrap for a long time now, so not too familiar with it's classes anymore ;), but I think if you really want to use it, you can easily find the matching classes within the bootstrap framework to replicate the little CSS this implementation needs (look at utility classes mainly)
PS: Ignore the JS code, it's just for demonstration purposes so you can dynamically add or remove items from the grid and see how it reacts.
function addItem(e) {
document.querySelector('.container').appendChild(document.querySelector('.col:first-of-type').cloneNode(true));
}
function removeItem(e) {
e.remove();

I have been experimenting with full responsive layouts between desktops, tablet, and mobile phone sizes for a bit but am having trouble with the layout below.
I was using a grid layout from bootstrap but since it is two columns, as the width shrinks, the second column of two goes below the left, main content section. I want to split it up as the screen caps below state.
This is the starting view:
This is what I want to happen:
This would be the mobile phone view:
So the wide view will get shrunk during testing and I want it to jump to the mobile view where the top side bar goes above the main content and matches the width of the main content while the bottom sidebar does the same thing to the bottom.
It is easy to put both sidebars on the bottom but I want to try to figure out the possibility of splitting it up.
For testing I am using flexbox, css3 and bootstrap5+ and no plugins or javascript.
Solution 1: You can use CSS float feature with float-end and float-start bootstrap classes ref:
<link href="https://cdnjs.cloudflare.com/ajax/libs/bootstrap/5.1.3/css/bootstrap.min.css" rel="stylesheet" />
<div class="container-fluid vh-100 vw-100 py-2 bg-light clearfix">
<div class="float-sm-end col-sm-4 col-12 h-25 bg-secondary">Sidebar Top</div>
<div class="float-sm-start col-sm-8 col-12 h-100 bg-warning">Content</div>
<div class="float-sm-end col-sm-4 col-12 h-25 bg-info">Sidebar bottom</div>
</div>
Go in Full page view and reduce browser width below 576px to see the responsive change.
I've used breakpoint small col-sm-* here, use different breakpoints to handle different devices.
There are only d-*-grid rules in entire boostrap v5.1.3 CSS file. Rest of the stuff is experimental.
Solution 2: Using flexbox, playing with order and wrap. Improved version of #Rana's answer:
<link href="https://cdnjs.cloudflare.com/ajax/libs/bootstrap/5.1.3/css/bootstrap.min.css" rel="stylesheet" />
<div class="d-flex flex-column flex-sm-wrap vh-100 vw-100 py-2 bg-light">
<div class="order-sm-1 order-2 col-sm-8 col-12 h-100 bg-warning">Content</div>
<div class="order-sm-2 order-1 col-sm-4 col-12 h-25 bg-secondary">Sidebar Top</div>
<div class="order-sm-3 order-3 col-sm-4 col-12 h-25 bg-info">Sidebar bottom</div>
</div>
You may want to try out Bootstrap's Flex order utility to achieve the desired result
https://getbootstrap.com/docs/5.0/utilities/flex/#order
Also, share a code example so others can see what you have already tried, I believe you may face some issues even with Flex's Order utility, but that depends on your HTML structure.
For such layout my preference would be to create a copy of the top column for mobile / desktop, and use d- utility to show hide the right one.
<div class="container">
<div class="row ">
<div class="col-12 d-md-none d-block">
<div class="box box-1">sidebar top col (only for mobile)</div>
</div>
<div class="col-md-8">
<div class="box box-2">main col</div>
</div>
<div class="col-md-4">
<div class="box box-3 d-none d-md-block">sidebar top col (only for desktop)</div>
<div class="box box-4">sidebar bottom col</div>
</div>
</div>
</div>

Alternatively if you are already using Bootstrap 5, then you should also consider using CSS Grid, Bootstrap 5 comes with a lot of useful utilities for that -
https://getbootstrap.com/docs/5.1/layout/css-grid/
If you do not want to duplicate your HTML to show one on desktop and the other on mobile then CSS Grid for layout is the best choice - it has some learning curve but it is worth trying out
You can try following properties
flex-flow: column;
flex-wrap: wrap/nowrap;
order: 1/2/3/....;
When screen-size reaches certain limit than change these values like in below snippet
.container {
display: flex;
flex-flow: column;
flex-wrap: wrap;
background-color: lightgray;
}
.containerBox {
width: 50%;
}
.containerBox1 {
background-color: lightgreen;
order: 2;
}
.containerBox2 {
background-color: yellow;
order: 1;
}
.containerBox3 {
background-color: lightblue;
order: 3;
}
#media screen and (max-width: 700px) {
.container {
background-color: grey;
flex-wrap: nowrap;
}
.containerBox {
width: 100%;
}
.containerBox1 {
order: 1;
}
}
<link href="https://cdnjs.cloudflare.com/ajax/libs/bootstrap/5.1.3/css/bootstrap.min.css" rel="stylesheet" />
<div class="container vh-100 vw-100">
<div class="containerBox containerBox1 h-25">Sidebar Top</div>
<div class="containerBox containerBox2 h-100">Content</div>
<div class="containerBox containerBox3 h-25">Sidebar bottom</div>
</div>
Using float-start for left column and float-end for right columns is the best solution. col-12 and col-sm-* were used only in order to defining width of columns. Avoid of using row class for parent div because this will force columns to act like flex items.
Also clearfix class for parent div is required to prevent overlapping following elements.

Give this a Try
I have a div, inside a bootstrap column, that has class position-fixed so that the contents inside are fixed relative to the viewport. I am able to horizontally align these contents but I am having trouble vertically aligning it.
I know there are many methods out there in bootstrap 4, but it all seems to break due to the position-fixed class. Either the contents disappear somewhere outside the page, or nothing happens.
<div class="container-fluid">
<div class="row">
<div class="col-md">
<div class="container">
<div class="row justify-content-md-center">
<div class="position-fixed h-100 col-md-auto">
<div class="text-center vertical-center">
<h2>Title</h2>
<p>Subtext</p>
<a data-toggle="modal" data-target="#Modal" href="#">Click me</a>
</div>
</div>
</div>
</div>
</div>
</div>
</div
If you want it to be fixed position, there's no reason to contain it inside the other elements (container, row, col) since as you said, it's positioning is relative to the viewport. Therefore, use custom CSS to center it...
.vertical-center {
position: fixed;
top: 50%;
left: 50%;
transform: translate(-50%, -50%);
}
https://www.codeply.com/go/rtOA3jgjPG
Or, to use the Bootstrap classes, make the fixed element a flexbox container using d-flex, and then align-items-center to center.
<div class="position-fixed h-100 col-md-auto d-flex align-items-center">
<div>centered content</div>
<div>
https://www.codeply.com/go/TmySmKXXjC
Apply Bootstrap's flexbox utilities to the parent of the div you're trying to center (this is a good cheatsheet of what different flex properties do if you need it):
<link href="https://stackpath.bootstrapcdn.com/bootstrap/4.1.3/css/bootstrap.min.css" rel="stylesheet"/>
<div class="container-fluid">
<div class="row">
<div class="col-md">
<div class="container">
<div class="row justify-content-md-center">
<div class="position-fixed h-100 col-md-auto d-flex align-items-center">
<div class="text-center vertical-center">
<h2>Title</h2>
<p>Subtext</p>
<a data-toggle="modal" data-target="#Modal" href="#">Click me</a>
</div>
</div>
</div>
</div>
</div>
</div>
</div>
Specifically, adding d-flex and align-items-center should work.
#OuterDiv {
position: fixed;
width: 100%;
height: 50px;
}
#InnerDiv {
display: inline-block;
top: 50%;
transform: translateY(-50%);
position: relative;
}
Please see code snipped: I am trying to align the divs with "Learn More" at the bottom of the columns at the same vertical height regardless of the height of the previous div.
Duplicate Disclaimer: I've been looking at How can I make Bootstrap columns all the same height? and How can I make Bootstrap 4 columns all the same height? which seem to be a similar problem. However, the solutions do not work for me as they are mostly for BS3 (e.g. I tried the examples with class="row-eq-height"), and most answers with regard to BS4 imply that the equal height is default in BS4.
However as you can see from the red borders, only the outer column height is "stretched" to the bottom by default, the inner one is only equal to text height. I'm very confused.

Also, I've tried various Bootstrap alignment options such as strechting the middle div with "align-items-stretch" and using "d-flex align-items-end" for the last div. Nothing works.
Columns in bootstrap are not display: flex and that is why the align-items-end is not working. Add the classes d-flex and flex-column to your column classes. Added the class .flex-1 and put this on your upper div.

EDIT: Also wanted to mention you could use a boostrap utility class mb-auto instead of flex-1

<div class="mb-auto">

<p class="body-block-3">one line text example</p>

</div>
However your upper div will not take up the entire space (stretch), not sure if this is an issue with your use case. If not, you would not have to make any new classes and would be following the docs on bootstrap's with align-item section
EDIT: Updated for .body-block-3 class
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?
DEMO
Bootstrap 5 (Updated 2021)
Bootstrap 5 is still flexbox based so vertical centering works the same way as it did in Bootstrap 4. For example, align-items-center (flex-direction: row) and justify-content-center (flex-direction: column) can used on the flexbox parent (row or d-flex).
Centering examples in Bootstrap 5
Vertical center (don't forget the parent must have a defined height!):
my-auto for centering inside flex (.d-flex) elements
my-auto can be used to center columns (.col-) inside row
align-items-center to center columns (col-*) inside row
Horizontal center:
text-center to center display:inline elements & column content
mx-auto for centering inside flex elements
mx-auto can be used to center columns (.col-) inside row
justify-content-center to center columns (col-*) inside row
Bootstrap 4.3+ (Update 2019)
There's no need for extra CSS. What's already included in Bootstrap will work. Make sure the container(s) of the form are full height. Bootstrap 4 now has a h-100 class for 100% height...
Vertical center:
<div class="container h-100">
<div class="row h-100 justify-content-center align-items-center">
<form class="col-12">
<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>
https://codeply.com/go/raCutAGHre
the height of the container with the item(s) to center should be 100%
(or whatever the desired height is relative to the centered item)
Note: When using height:100% (percentage height) on any element, the element takes in the height of it's container. In modern browsers vh units height:100vh; can be used instead of % to get the desired height.
Therefore, you can set html, body {height: 100%}, or use the new min-vh-100 class on container instead of h-100.
Horizontal center:
text-center to center display:inline elements & column content
mx-auto for centering inside flex elements
offset-* or mx-auto can be used to center columns (.col-)
justify-content-center to center columns (col-*) inside row
Vertical Align Center in Bootstrap
Bootstrap 4 full-screen centered form
Bootstrap 4 center input group
Bootstrap 4 horizontal + vertical center full screen
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>
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>
<div class="p-2">

</div>
</div>
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">
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%;
}
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>
Try the code given below while using v4 or v5.
<div class="d-flex align-items-center justify-content-center" style="height:100vh;">
Vertically and Horizontally Aligned :)
</div>
...OR... You can use these classes if using v5.
<div class="position-absolute top-50 start-50 translate-middle">
Vertically and Horizontally Aligned :)
</div>
Do this, and that's it :)

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'
}
From bootstrap v5.0 just:
<div class="position-absolute top-50 start-50 translate-middle">
centred
</div>
Bootstrap way
HTML
<div class="row top-row">
<div class="col center-text">
<H1>Center Text Horizantally and vertically</H1>
</div>
</div>
Custom CSS
.top-row{
height: 300px; //It's important to set height
}
.center-text{
display: flex;
align-items: center;
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>
which gives the result:
I am required to show form vertically center inside container-fluid so I developed my own code for the same.
