Bootstrap Center Vertical and Horizontal Alignment
(17 answers)
Closed last year.
I have a problem with my CSS. I have a panel form in my index page and I want to move it in the middle of the page vertically and horizontally. But I don't know how to create a CSS for this.
Here's my sample code:
<div class="login_header"></div>
<div class="container" style="text-align: center;">
<div class="col-md-6 col-md-offset-3">
<div class="panel_form panel panel-default">
<div class="panel-content">
<h1>test</h1>
</div>
<div class="panel-footer">
<p>test</p>
</div>
</div>
</div>
</div>
<footer class="footer"></footer>
I have a CSS like this:
.login_header { min-height: 50px; background-color: #f5f5f5; }
.panel_form {
/* I don't have an idea with this */
}
.footer {
position: absolute;
bottom: 0;
width: 100%;
height: 50px;
background-color: #f5f5f5;
}
I am not good enough in CSS that's why I need your help. That's all thanks.. :)
Bootstrap 4:
<div class=" h-100 d-flex justify-content-center align-items-center">
<div>
Items are Centered horizontally and vertically
</div>
</div>
JsFiddle
Some of the other answers on this question use CSS hacks with tables and custom CSS classes. As the poster asked "How to center vertically and horizontally using Bootstrap", here is how to do that using only Bootstrap 4 utility classes:
<div class="d-flex justify-content-md-center align-items-center vh-100">
<p>Your Content</p>
</div>
Something of note is that due to the styling on the parent div, when adding additional elements in the same div, they will appear beside the first one, rather than below it. To fix this, just add an additional div inside the parent to reset the styling.
<div class="d-flex justify-content-md-center align-items-center vh-100">
<div>
<p>Content 1</p>
<p>Content 2</p>
</div>
</div>
This does work with Bootstrap flex, I've found that it works best when placed inside a flex component like this, rather than wrapping the entire row.
<div class="container">
<div class="row">
<div class="col-md-6">
<div class="d-flex justify-content-md-center align-items-center vh-100">
<p>Content 1</p>
</div>
</div>
<div class="col-md-6">
<div class="d-flex justify-content-md-center align-items-center vh-100">
<p>Content 2</p>
</div>
</div>
</div>
</div>
Here is a breakdown of each class:
d-flex: Effectively display: flex, allows the div to grow or shrink depending on the amount of content.
justify-content-md-center: Justifies content in the center of the page, can also be replaced with justify-content-sm-center or justify-content-lg-center to change the breakpoint.
align-items-center: Centers the alignments of all items in a div.
vh-100: Sets the height of the div to 100vh, or 100 "vertical height". This ensures that the div is the correct height to allow for vertical alignment.
I found some of the answers very difficult to implement. However, this question seems to be one of the most basic ones and so here's an answer that someone else like me might find useful.
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div class="container" style="display: flex; justify-content: center; align-items: center; height: 100vh">
hello world!
</div>
So, check this out; it's pretty cool
HERES A CODE PEN TO SEE IT IN ACTION
html, body 100% width and height;
container with relative or fixed positioning with 100% width and height, if you want to center in viewport. Size doesn't matter if you just want to ceter it within the element.
centered thing needs absolute positioning, a top and left of 50%, then use transform: translate(-50%, -50%);
regardless of its size, it's centered in viewport
CSS
* {
margin: 0;
padding: 0;
box-sizing: border-box;
}
html,
body {
width: 100%;
height: 100%;
}
#outer {
position: relative;
width: 100%;
height: 100%;
background: #BADA55;
}
#outer #container {
background-color: #f3f3f3;
color: #663399;
padding: 15px 25px;
width: 100%;
max-width: 300px;
position: absolute;
transform: translate(-50%, -50%);
left: 50%;
top: 50%;
}
LESS version
* {
margin: 0;
padding: 0;
box-sizing: border-box;
}
html, body {
width: 100%;
height: 100%;
}
#outer {
position: relative;
width: 100%;
height: 100%;
background: #BADA55;
#container {
background-color: #f3f3f3;
color: #663399;
padding: 15px 25px;
width: 100%;
max-width: 300px;
position: absolute;
transform: translate(-50%, -50%);
left: 50%;top: 50%;
}
}
What worked for me is this:
<div class="container h-100">
<div class="d-flex justify-content-md-center align-items-center vh-100">
<p>Your Content</p>
</div>
</div>

While I haven't found a solution to the general problem in pure Bootstrap 5, here is a solution that works with just a little additional CSS. Please test by changing the browser window size, or using the Responsive Mode of your browser, but not both at once, since they don't behave well together.
This example centers a 50% wide and high div, and centers the text inside it.
It works perfectly down to about a 200px by 200px window.
See Code Pen https://codepen.io/david263/pen/eYvOGOB and use Settings > Full screen mode.
<style type="text/css">
/* Required for proper centering */
html, body{
height:100vh;
width:100vw;
}
</style>
<!-- Outer container, full page width and height, red border -->
<div class="container-fluid d-flex justify-content-center align-items-center" style="height:100vh; overflow:hidden; border: 2px solid red">
<!-- Inner row, half the width and height, centered, blue border -->
<div class="row text-center d-flex align-items-center" style="overflow:hidden; width:50vw; height:50vh; border: 1px solid blue">
<!-- Innermost text, wraps automatically, automatically centered -->
<h2>Center This Text (Even if Wrapped) in all Viewport Sizes</h2>
</div> <!-- Inner row -->
</div> <!-- Outer container -->
Give the outer div
display: table;
and the inner div
display: table-cell
Then you can use
vertical-align: center
on the inner div

I have been searching for a solution to this problem for almost two weeks now and I am still completely lost. I'm making a simple landing page and I don't want any scrolling. I need a header followed by a bootstrap row containing a paragraph and an image. Here is my ms paint example:
Simple enough right? Well I can not for the life of me figure out how to get that image to shrink to fit into that row. Here is what is happening to me now. Note: When you run the snippet on stackoverflow the window is to small. It is easier to see whats going on with the JSFiddle
body, html {
height: 100%;
width: 100%;
position: absolute;
margin: 0;
}
.content {
}
img {
height: 100%;
}
h1 {
background-color: white;
}
.banner {
height: 90%;
background-color: red;
}
<link rel="stylesheet" href="https://stackpath.bootstrapcdn.com/bootstrap/4.5.0/css/bootstrap.min.css" integrity="sha384-9aIt2nRpC12Uk9gS9baDl411NQApFmC26EwAOH8WgZl5MYYxFfc+NcPb1dKGj7Sk" crossorigin="anonymous">
<div class="banner">
<h1>
Header
</h1>
<div class="row content">
<p> Hello World </p>
<img src="https://upload.wikimedia.org/wikipedia/commons/8/89/Portrait_Placeholder.png">
</div>
</div>
Result
The part that throws me off is that the .row extends beyond it's parent container .banner. How do we force this to stay inside that red area?
I've messed with object-fit, flex-grow, flex-shrink, a flex-basis and none of these seem to create the desired behavior. I'm going insane trying to figure this problem out. Maybe flexbox is the wrong tool to use here? But I'm trying to take advantage of the bootstrap grid system's media queries. Thanks in advance for any help!
Note: The reason I have everything nested in the <div class=".banner"> is because I want the header to have a shadow onto the red background.
Edit
The root of my question is how do I get an image to fit inside of a row that only covers the red area?
You can update your code like below:
img {
/* this will make the image stretch and no overflow*/
height:0;
min-height:100%;
/**/
}
h1 {
background-color: white;
}
.banner {
height: 90vh;
background-color: red;
}
<link rel="stylesheet" href="https://stackpath.bootstrapcdn.com/bootstrap/4.5.0/css/bootstrap.min.css" >
<div class="banner d-flex flex-column"> <!-- flex container here -->
<h1>
Header
</h1>
<div class="d-flex content flex-grow-1 p-2"> <!-- flex-grow here to fill remaining space -->
<p> Hello World </p>
<img src="https://upload.wikimedia.org/wikipedia/commons/8/89/Portrait_Placeholder.png" class="ml-auto">
</div>
</div>
Try this:
<div class="banner">
<h1>Header</h1>
<div class="row content">
<div class="col-6">
<p> Hello World</p>
</div>
<div class="col-6">
<img src="https://upload.wikimedia.org/wikipedia/commons/8/89/Portrait_Placeholder.png">
</div>
</div>
</div>
Working example: Codepen.
PS.: In my example I tried to follow your ms paint example.
Use display:block to the img & this also helps in responsiveness you can check the fiddle if you want to explore.
OR
You can also look into vh for height and vw for width that will take care of all screen resolutions.

I've read quite a few similar questions to mine but none is quite the same or has an answer which works for me.
I'm using Twitter Bootstrap 3. I have two rows, and each row contains a col-sm-12 div, so they're the same width. The content in the first row is wider than its container but I have overflow:auto set on the element containing the two rows so a horizontal scrollbar is displayed and the content can be seen using that, so that's fine.
In the second row I have a div to which I'm applying a jQuery plugin (jqxGrid, for what it's worth). I've set the width option of the plugin to be "100%". The resultant grid's content is also too wide for its container but because of the way the jQuery plugin creates the grid it constricts the grid's width to 100% of its parent's width rather than overflowing.
So what I really need is for the .row elements to all be as wide as the widest overflowing content so that when the jQuery plugin evaluates the width of its parent so as to set its own width, the resultant grid ends up being as wide as the overflowing content in the first row.
I've made a fiddle which I hope will illustrate the problem. I feel that at its heart this is a CSS problem so a pure CSS solution would be excellent, but I doubt that that's possible.
.wrapper {
color: #fff;
padding: 10px;
}
.container-fluid {
background-color: #333;
overflow: auto;
}
.row1 {
background-color: yellow;
}
.row2 {
background-color: orange;
}
.short-content {
background-color: red;
width: 100%;
}
.long-content {
width: 2000px;
background-color: blue;
}

THe jQuery plugin here is too wide to fit but won't overflow because its width is set to match its parent.

</div>
To my understanding, wrapping each .col-sm-12 into their own parent .row is a verbose way of having all .col-sm-12 in a single .row container, as .col-sm-12s are always wrapping into a new line.
So, in case your setup allows for removing the intermediate .row tags, the only additional line of css you have to write is float: left; on .row. (In the example below I used the id #custom on .container-fluid to isolate this modification from the rest of your page).
body {
color: #fff;
padding: 10px;
}
.container-fluid {
background-color: #333;
overflow: auto;
}
.row1 {
background-color: yellow;
}
/*.row2 {
background-color: orange;
}*/
.short-content {
background-color: red;
width: 100%;
}
.long-content {
width:2000px;
background-color: blue;
}
#custom .row {
float: left;
}

I'm looking to learn how I can position images in CSS, multiple ones, without affecting my footers position, size, etc.
I coded some CSS I thought would work, but it messed up my footers position. (It wouldn't stay at the bottom.)
So, I fixed that issue but found the code I wrote for the image position messed with the footers position.
I don't really know how, but I would like to have my images positioned, perhaps by px/space.. they just need to look good in a row spaced.
The example is in red, is how I want it to look.
look here for an example of how I want it to look.
HTML
<div class="batesimg">
<p><strong>Bates</p></strong>
<div class="shadow"> <!-- makes a shadow, surrounding the characters picture. -->
<img src="images/bates.png" alt="Bates" width="150" height="150"> <!-- defines the img -->
CSS
/* Bates profile picture. */
.batesimg { /* or whatever class name works for you */
position: auto;
left:250px;
top:250px;
margin-right: 500px;
}
NOTE, the css above isn't positioning the image how i want it, showed in the image example, can someone help me positiong the image like i have it in my example image?
Thanks!
You want to repeat same type of pattern of name,img and descriptions. We will call this 'card'. Now you have two problems in hand.
1) Placing multiple cards in page. For this use some layout like flexbox.
2) Setting inside of card properly..
/*1st Problem*/
#flex-container{
display: flex;
flex-wrap:wrap;
width: 600px;
justify-content: space-around;
}
#flex-container>div.card{
flex-grow:0;
flex-shrink:0;
}
/*1st Problem ends*/
/*2nd Problem*/
.card{
width: 200px;
height:calc(200px + 2em);
}
.card>.name ,.card>.desc{
width: 100%;
text-align: center;
}
.card>div.img{
position: relative;
margin-left: 25px;
width: 150px;
height: 150px;
border-radius: 100%;
}
/*2nd Problem ends*/
.card:nth-child(1) div.img{background-color: red;}
.card:nth-child(2) div.img{background-color: green;}
.card:nth-child(3) div.img{background-color: blue;}
.card:nth-child(4) div.img{background-color: yellow;}
/*Centering Content*/
#flex-container{
margin: 0 auto;
/*top,bottom both zero.. and left,right both auto..
handling margin is complicated..read about them
*/
}
<div id="flex-container">
<div class="card">
<div class="name">Name1</div>
<div class="img"></div>
<div class="desc">Desc1</div>
</div>
<div class="card">
<div class="name">Name2</div>
<div class="img"></div>
<div class="desc">Desc2</div>
</div>
<div class="card">
<div class="name">Name3</div>
<div class="img"></div>
<div class="desc">Desc3</div>
</div>
<div class="card">
<div class="name">Name4</div>
<div class="img"></div>
<div class="desc">Desc4</div>
</div>
</div>

Here's a image of what i'm trying to do vs what i'm getting
Basically i'm floating all the div left but because the first div's height is taller than the rest, its leaving a gaping hole.
The generated divs are products in a shop collection.
while the tall first div is a filter menu that's always present.
How do i get all the div to fluidly float left and fill in the empty space.
Should i be looking at flex box? And its NOT a masonry / isotope kind of layout. only the first div has a taller height
here the page im working on:

I've searched high and low and cannot find a solution specific to this problem. I'm trying to accomplish the following:
Have a container DIV defined with a percentage height to serve as max-size container
A secondary container DIV that provides a content size-based borde
Have a header div that is fixed at the top of that DIV
Have a list of DIVs (table-like) under the header
When the list is short, the border is reduced to size of content
When list if long (> height of outer container), scrollbar is shown for DIV list and not header.
I put together the following simplified version:
<html>
<head>
<style type="text/css">
.panel { height: 10%; border: 1px solid red; overflow: hidden; margin-top: 10px; }
.sizer { max-height: 100%; border: 1px solid blue; }
.header { border-bottom: 1px solid black; }
.scroll { max-height: 100%; overflow: auto; }
</style>
</head>
<body>
<div class="panel">
<div class="sizer">
<div class="wrap">
<div class="header">Header</div>
<div class="scroll">
<div>Line1</div>
<div>Line2</div>
</div>
</div>
</div>
</div>
<div class="panel">
<div class="sizer">
<div class="wrap">
<div class="header">Header</div>
<div class="scroll">
<div>Line1</div>
<div>Line2</div>
<div>Line3</div>
<div>Line4</div>
<div>Line5</div>
<div>Line6</div>
<div>Line7</div>
<div>Line8</div>
<div>Line9</div>
<div>Line10</div>
<div>Line11</div>
<div>Line12</div>
</div>
</div>
</div>
</div>
</body>
</html>
The two red boxes should be fixed size. Check
The blue box should size to be the size of the content or size of red box maximum. Check
When contents in lower exceed red box size, scrollbar should be displayed under header. Fail
Any change I make that gets the scrollbar displayed causes the top blue box to enlarge to the size of it's container, red box. e.g., { .scroll height: 100% }
(The DIV.wrap does have a purpose - just not in this example. It is intended to provide a double-border effect on the sizer, so it should be the same size as sizer all the time).
Also, I have figured out some solutions where I used fixed (px) sizes for the DIVs, but this is not necessarily desired. Especially on DIV.panel - this must be set to a percentage height.
Not completely sure i understand the question, but if you want the scroll on the list but not on the header, have you tried:
overflow-y:scroll;
on the "scroll" div instead of
overflow:auto?
Let me know
Ok i think maybe i worked it out. I think cause you have overflow:hidden and a height on the container div, and not the variable scroll div. Just try the code below and let me know. I have added the height of 10% to the scroll div and not the overall container. Hope thats what you were looking for
