This question already has an answer here:
I'm trying to horizontally center a <div> block element on a page and have it set to a minimum width. What is the simplest way to do this? I want the <div> element to be inline with rest of my page. I'll try to draw an example:
page text page text page text page text
page text page text page text page text
-------
| div |
-------
page text page text page text page text
page text page text page text page text
</div>

In the case of a non-fixed width div (i.e. you don't know how much space the div will occupy).
#wrapper {
background-color: green; /* for visualization purposes */
text-align: center;
}
#yourdiv {
background-color: red; /* for visualization purposes */
display: inline-block;
}<div id="wrapper">
<div id="yourdiv">Your text</div>
</div>Keep in mind that the width of #yourdiv is dynamic -> it will grow and shrink to accommodate the text inside it.
You can check browser compatibility on Caniuse
</div>
.center {
margin-left: auto;
margin-right: auto;
}
Minimum width is not globally supported, but can be implemented using
.divclass {
min-width: 200px;
}
Then you can set your div to be
<div class="center divclass">stuff in here</div>
margin: 0 auto;
as ck has said, min-width is not supported by all browsers
CSS, HTML:
div.mydiv {width: 200px; margin: 0 auto}<div class="mydiv">
I am in the middle
</div>Your diagram shows a block level element also (which a div usually is), not an inline one.
Of the top of my head, min-width is supported in FF2+/Safari3+/IE7+. Can be done for IE6 using hackety CSS, or a simple bit of JS.
</div>
In most browsers this will work:
div.centre {
width: 200px;
display: block;
background-color: #eee;
margin-left: auto;
margin-right: auto;
}<div class="centre">Some Text</div>In IE6 you will need to add another outer div:
div.layout {
text-align: center;
}
div.centre {
text-align: left;
width: 200px;
background-color: #eee;
display: block;
margin-left: auto;
margin-right: auto;
}<div class="layout">
<div class="centre">Some Text</div>
</div></div>
you can use the position:relative; and then set the left and the top values:
.cenverDiv{
position:relative;
left:30%;
top:0px;
}
you can use margin: 0 auto on your css instead of margin-left: auto; margin-right: auto;
.center {
height: 20px;
background-color: blue;
}
.center>div {
margin: auto;
background-color: green;
width: 200px;
}<div class="center">
<div>You text</div>
</div></div>
Using jQuery:
$(document).ready(function() {
$(".myElement").wrap( '<span class="myElement_container_new"></span>' ); // for IE6
$(".myElement_container_new").css({// for IE6
"display" : "block",
"position" : "relative",
"margin" : "0",
"padding" : "0",
"border" : "none",
"background-color" : "transparent",
"clear" : "both",
"text-align" : "center"
});
$(".myElement").css({
"display" : "block",
"position" : "relative",
"max-width" : "75%", // for example
"margin-left" : "auto",
"margin-right" : "auto",
"clear" : "both",
"text-align" : "left"
});
});
or, if you want to center every element with class ".myElement":
$(document).ready(function() {
$(".myElement").each(function() {
$(this).wrap( '<span class="myElement_container_new"></span>' ); // for IE6
$(".myElement_container_new").css({// for IE6
"display" : "block",
"position" : "relative",
"margin" : "0",
"padding" : "0",
"border" : "none",
"background-color" : "transparent",
"clear" : "both",
"text-align" : "center"
});
$(this).css({
"display" : "block",
"position" : "relative",
"max-width" : "75%",
"margin-left" : "auto",
"margin-right" : "auto",
"clear" : "both",
"text-align" : "left"
});
});
});
The best response to this question is to use margin-auto but for using it you must know the width of your div in px or %.
CSS code:
div{
width:30%;
margin-left:auto;
margin-right:auto;
}
If your <div> has position: absolute you need to use width: 100%;
#parent {
width: 100%;
text-align: center;
}
#child {
display: inline-block;
}
Here I add proper answer
You can use this snippet code and customize. Here I use 2 child block.This should show center of the page. You can use one or multiple blocks.
<html>
<head>
<style>
#parent {
width: 100%;
border: solid 1px #aaa;
text-align: center;
font-size: 20px;
letter-spacing: 35px;
white-space: nowrap;
line-height: 12px;
overflow: hidden;
}
.child {
width: 100px;
height: 100px;
border: solid 1px #ccc;
display: inline-block;
vertical-align: middle;
}
</style>
</head>
<body>
<div class="mydiv" id="parent">
<div class="child">
Block 1
</div>
<div class="child">
Block 2
</div>
</div>
</body>
</html>
You should use position: relative and text-align: center on the parent element and then display: inline-block on the child element you want to center. This is a simple CSS design pattern that will work across all major browsers. Here is an example below or check out the CodePen Example.
p {
text-align: left;
}
.container {
position: relative;
display: block;
text-align: center;
}
/* Style your object */
.object {
padding: 10px;
color: #ffffff;
background-color: #556270;
}
.centerthis {
display: inline-block;
}<div class="container">

<span class="object centerthis">Something Centered</span>

The title of the question and the content is actually different, so I will post two solutions for that using Flexbox.
I guess Flexbox will replace/add to the current standard solution by the time IE8 and IE9 is completely destroyed ;)
Check the current Browser compatibility table for flexbox
Single element
.container {
display: flex;
justify-content: center;
}<div class="container">
<img src="http://placehold.it/100x100">
</div>Multiple elements but center only one
Default behaviour is flex-direction: row which will align all the child items in a single line. Setting it to flex-direction: column will help the lines to be stacked.
.container {
display: flex;
flex-direction: column;
}
.centered {
align-self: center;
}<div class="container">
<p>Lorem Ipsum is simply dummy text of the printing and typesetting industry. Lorem Ipsum has been the industry's standard dummy text ever since the 1500s, when an unknown printer took a galley of type and scrambled it to make a type specimen book. It has survived not only five centuries, but also the leap into electronic typesetting, remaining essentially unchanged.

If old browsers are not an issue, use HTML5 / CSS3. If they are, apply polyfills and still use HTML5 / CSS3. I assume that your div has no margins or paddings here, but they are relatively easy to account for. The code follows.
.centered {
position: relative;
left: 50%;
transform: translateX(-50%);
}
What this does is:
div relative to its container;div's left boundary at 50% of its container width horizontally;div's own width.It is easy to imagine this process to confirm that the div would be horizontally centered eventually. As a bonus, you can center vertically at no additional cost:
.centered-vertically {
position: relative;
top: 50%;
transform: translateY(-50%);
}
The advantage of this approach is that you don't have to do any counterintuitive stuff, such as considering your div a text of sorts, wrapping it in a (often semantically useless) additional container, or giving it a fixed width, which is not always possible.
Don't forget vendor prefixes for transform if needed.
I use div and span tags together with css properties such as block, cross-browser inline-block and text-align center, see my simple example
<!DOCTYPE html>
<html>
<head>
<title>Page Title</title>
<style>
.block{display:block;}
.text-center{text-align:center;}
.border-dashed-black{border:1px dashed black;}
.inline-block{
display: -moz-inline-stack;
display: inline-block;
zoom: 1;
*display: inline;
}
.border-solid-black{border:1px solid black;}
.text-left{text-align:left;}
</style>
</head>
<body>
<div class="block text-center border-dashed-black">
<span class="block text-center">
<span class="block">
<!-- The Div we want to center set any width as long as it is not more than the container-->
<div class="inline-block text-left border-solid-black" style="width:450px !important;">
jjjjjk
</div>
</span>
</span>
</div>
</body>
</html>
In your html file you write:
<div class="banner">
Center content
</div>
your css file you write:
.banner {
display: block;
margin: auto;
width: 100px;
height: 50px;
}
works for me.
Usage of margin-left:auto and margin-right:auto may not work in certain situations. Here is a solution what will always work. You specify a required width and than set a left-margin to a half of the remaining width.
<div style="width:80%; margin-left:calc(10%);">
your_html
</div>
Add this class to your css file it will work perfectly steps to do:
1) create this first
<div class="center-role-form">
<!--your div (contrent) place here-->
</div>
2) add this to your css
.center-role-form {
width: fit-content;
text-align: center;
margin: 1em auto;
}
Please use below code your div will be in center
.class-name{
display:block;
margin:0 auto;
}
After nine years I thought it was time to bring a new version. Here are my two (and now one) favourites.
Margin
Set margin to auto. You should know the direction sequence is margin: *top* *right* *bottom* *left*; or margin: *top&bottom* *left&right*
aside{
display: block;
width: 50px;
height: 100px;
background-color: green;
float: left;
}
article{
height: 100px;
margin: 0 0 0 50px; /* 50px aside width */
background-color: grey;
}
div{
margin: 0 auto;
display:block;
width: 60px;
height: 60px;
background-color: blue;
color: white;
}<!DOCTYPE html>
<html>
<head>
</head>
<body>
<aside>
</aside>
<article>
<div>The div</div>
</article>
</body>
</html>Center: Depricated, don't use this!
Use <center></center> tags as a wrap around your <div></div>.
Example:
aside{
display:block;
background-color:green;
width: 50px;
height: 100px;
float: left;
}
center{
display:block;
background-color:grey;
height: 100px;
margin-left: 50px; /* Width of the aside */
}
div{
display:block;
width: 60px;
height: 60px;
background-color:blue;
color: white;
}<!DOCTYPE html>

If you know the width of your div and it is fixed, you can use the following css:
margin-left: calc(50% - 'half-of-your-div-width');
where 'half-of-your-div-width' should be (obviously) the half of the width of your div.
