how could i vertically center a <div> within a <div> ?
my code so far:
<div style="height:322px;overflow:auto;">
<div style="border: Solid 1px #999999;padding:5px;">
</div>
</div>
i have tried "top:50%;" and "vertical-align:middle;" without success
EDIT: okay so it's been discussed a lot. and i've maybe started another mini flame war. but for argument sake, how would i do it with a table then? i've used css for everything else so far so it's not like i'm not trying to employ "good practices".
EDIT: the inner div does not have a fixed height
In short, you're stuffed. More on this in a recent question I asked Can you do this HTML layout without using tables? Basically the CSS fanatics need to get a grip and realize there's simply some things you can't do (or can't do well) without tables.
This anti-table hysteria is nothing short of ridiculous.
Table cells handle vertical centering really well and are backwards compatible as far as you could possibly care about. They also handle side-by-side content way better than floats, relative/absolute positioning or any of the other CSS type methods.
Joel coined (or at least popularized) the term "architect astronauts" in Don't Let Architecture Astronauts Scare You. Well, in that same vein I think the term "CSS Astronaut" (or "CSS Space Cadet") is equally appropriate.
CSS is an incredibly useful tool but it also has some pretty serious limitations. My favourite ishow numbered lists may only appear as "3." but not "3)" or "(3)" (at least prior to CSS3 generated content--or is it CSS2.1? Either way it's not widely supported). What an oversight.
But bigger than that is vertical centering and side-by-side layout. These two areas are still a huge problem for pure CSS. Another poster decided the relative positioning combined with negative margin heights was the way to go. How is that any better than:
<html>
<head>
<title>Layout</title>
<style type="text/css">
#outer { height: 200px; border: 1px solid black; width: 600px; background-color: #DDD; }
#inner { width: 150px; border: 1px solid red; background: yellow; margin: auto; line-height: 100%; }
</style>
</head>
<body>
<table>
<tr>
<td id="outer">
<div id="inner">Inner</div>
</td>
</tr>
</table>
</body>
</html>
which will work everywhere, everytime.
Here is an article on vertical centering in CSS. To achieve a similar thing they use three nested divs with relative+absolute+relative positioning just to get vertical centering. I'm sorry but whoever wrote that--and anyone who thinks that's a good diea--has simply lost the plot.
A counterargument is given in Tables vs CSS: CSS Trolls begone. The proof really is in the pudding. The vast majority of the top 20 (Alexa) sites still use tables for layout. With good reason.
So decide for yourself: do you want your site to work and spend less time getting it to work? Or do you want to be a CSS Astronaut?
It's non-trivial, there can be caveats, and it's not something CSS handles well at this point.
It is however quite widely discussed and googleable. This is a good example.
Whatever you do, please don't fallback to tables.
Edit: this is ridiculous, the following works perfectly well in a strict doc without resorting to table markup:
<style type="text/css">
.outer {height: 322px; overflow: hidden; position: relative;}
*|html .outer {display: table; position: static;}
.middle {position: absolute; top: 50%;}
*|html .middle {display: table-cell; vertical-align: middle; position: static;}
.inner {position: relative; top: -50%; overflow: auto;}
*|html .inner {position: static; max-height: 322px;}
</style>
<!--[if IE]>
<style>
.inner {height: expression(Math.min(this.scrollHeight,322)+'px'); width: 100%;} /* for explorer only */
</style>
<![endif]-->
<div class="outer">
<div class="middle">
<div class="inner">
Any text any height
</div>
</div>
</div>
I like this solution best. It is for IE8+, and is easy to understand.
<style>
/* Can be any width and height */
.block {
height:500px;
text-align: center;
}
/* The ghost, nudged to maintain perfect centering */
.block:before {
content: '';
display: inline-block;
height: 100%;
vertical-align: middle;
margin-right: -0.25em; /* Adjusts for spacing */
}
/* The element to be centered, can be any width or height */
.centered {
display: inline-block;
vertical-align: middle;
width: 300px;
}
</style>
<div class="block"><div class="centered">Centered Content</div></div>
top: 50%; should work. you need to put margin-top to negative half of the height or it will start in the middle. Therefore, you need the height of the inner div. You also probably need position:relative;
Something like this for you inner div.
position:relative;
top: 50%;
height:80px;
margin-top: -40px; /*set to a negative number 1/2 of your height*/
Not very neat working with negative sizes (what does it even mean?) but maybe the easiest way.
<div style="display: table; height: 400px; #position: relative; overflow: hidden;">
<div style=" #position: absolute; #top: 50%;display: table-cell; vertical-align: middle;">
<div style=" #position: relative; #top: -50%">
vertically centered
</div>
</div>
</div>

Two techniques of many
Browser compatibility of the following has been tested in IE only. Modern browsers should handle these no problem.
#1 - Absolute and auto margin
Compatibility: IE 8 +
The combination of top, right, bottom, left and margin: auto centers the div vertically and horizontally.
The width and height are needed, but can be percentages
Can also be applied to an inner div with the parent set position: relative
Note: A max-width and max-height instead of a percentage height is possible IE 9 +. IE 8 requires a height.
html,
body {
height: 100%;
}
.outer {
background: #ff8f00;
height: 50%;
width: 50%;
margin: auto;
position: absolute;
top: 0;
right: 0;
bottom: 0;
left: 0;
}
<div class="outer"></div>
#2 - Flexbox
Compatibility: IE 11. See here for other browser support.
Using Flexbox and flexible vw and vh lengths
body {
margin: 0;
}
.outer {
display: flex;
align-items: center;
justify-content: center;
height: 100vh;
}
.inner {
width: 50vw;
height: 50vh;
background: #ff8f00;
}
<div class="outer">
<div class="inner">
</div>
</div>
Do you absolutely need to do this with css? The above link looks pretty good, but you could get a result using javasctipt/jquery - determine the height of the innter div and adjust the margin.padding accordingly. Something similar to: (jquery)
var gap = ( $('the-outer-div').height() - $('the-inner-div').height() ) /2;
$('the-inner-div').css( "margin-top" , gap );
A table isn't necessary if you're willing to use the flexbox display model.
E.g.
<div style="height: 322px; width: 200px; display: flex; background: gray;">
<div style="border: Solid 1px #999999; padding:5px; margin: auto;">
This text would be both vertically AND horizontally centered, if it's inner height and width were less than the parent's height and width.
</div>
</div>
If you just want vertical centering use the rule "margin: auto 0;" in the child div.
p.s. You'll have to prefix your use of flexbox if you want cross-browser compatibility (e.g. "display: -webkit-flexbox;")
The display: flex property works especially well for centering, both vertically and horizontally. For vertical centering, add the properties display: flex and justify-content: center to the container.
Try line-height

I've run into a bit of a snag whilst developing the frontend for a website. I'm competent with CSS, but not fantastic. Anyway, I've created a jsFiddle here that illustrates my problem.
On each page of my website, at the top of the content section, I have a banner image. I wish to put a two colour divider seperating this banner from the content. (As is shown in the mockup my designer gave me: https://www.dropbox.com/s/d9opotyiyp0yc9o/menus.jpg)
I'd like to do this in pure CSS+HTML, without just chucking an image in. Anyway, I've done so using the following code:
<img class="banner" src="http://regency.ymindustries.com/static/images/winelist.jpg" style="width: 100%;">
<div>
<div style="width:30%; height: 10px; display: inline-block; background: #6C210C"></div><div style="width:70%; height:10px; display: inline-block; background: #E5C697;"></div>
</div>
(Please forgive the inline CSS, it's just for demonstration purposes. Also, unfortunately, if I put the second div on a newline and indent it, it creates whitespace)
The issue I'm having is that there is a large gap between the divider and the image. I have tried adding margin: 0px and padding: 0px to all the relevant elements, and the whitespace is still there.
Could someone help me out please?
Thanks,
YM
To me it's a vertical alignment issue. You can try
.banner {
display: block;
width: 100%;
}
div {
height: 10px;
vertical-align: top;
}
That way you don't have to use negative margins (which aren't wrong, just controversial practice).
Check it out here
you can make the position relative and then set the top to something minus. ex:
position: relative;
top:-10px;
left:0px;
this is actually float problem
<img class="banner" src="http://regency.ymindustries.com/static/images/winelist.jpg">
<div style="">
<div style="float:left;width:30%; height: 10px; display: inline-block; background: #6C210C"></div><div style="width:70%;float:left; height:10px; display: inline-block; background: #E5C697;"></div>
</div>
css
.banner {
width:100%;
float:left;
}
http://jsfiddle.net/eLbUU/4/
using display block and floating the divs, also making sure the img itself is display block with overflow hidden I was able to tighten up the stripes to the img : fiddle
.banner {
width:100%;
display: block;
overflow: hidden;
}
div div{
float: left;
}
First of all, put the darker brown in the lighter brown div. That way, when the window is re-sized, you don't compromise the sizing percentage and/or spacing.
<div style="width:100%; height:10px; display: inline-block; background: #E5C697;"> <div style="width:30%; height: 10px; background: #6C210C;"></div></div>
And with the space, you can either use negative margins or floats like others have mentioned.
.banner {
width:100%;
/* margin-bottom to the banner is negative which moves the div upward */
margin-bottom: -10px;
}
fiddle here
Putting display: block; for the image class and float:left; for all other elements may help.
.banner {
width:100%;
display:block;
float:left;
}

I'm trying to rewrite a site in proper HTML. The site I'm trying to replace was a complete mess. I've run into a problem where I can't get a <table> to fill the height of the <td> it's contained in. I've tried setting height: 100% on the <table>, which based on google and stackoverflow research should work, but I must be missing something stupid. I had tried to do the same thing with <divs> before switching to tables, but I'm not opposed to going back to <divs> if someone can suggest how to do it.
The content I'm developing is currently here: http://96.0.22.228/
Due to project time constraints, I've had to use bad hacks to get the pages looking correctly. I'm not declaring a <doctype> and I'm forcing IE to use IE7-quirks mode. I'd love to have recommendations on how to do this layout in a proper manner using HTML5 and CSS. It does not have to support older browsers, but it does have to look the same in the latest versions of Chrome, Firefox and IE. I'd also like to to do away with the images for the menus and style everything in CSS for the border frames and the menu text.
Even though I've had to complete the site as is, I'm open to going back and fixing it later if there's a good answer to this problem.
100% height in a table cell is always a pain. Technically speaking a TD has no height (because that depends on its contents). What you are asking the browser to do is make the child 100% of its parent, which is 100% of its child, which is 100% of its parent ... You can see how that might be a problem.
You could try adding an explicit height to the TD and using table-layout:fixed on the table. At least that way the browser knows the height of the parent without needing the height of the child but that still may not work.
You might need to rethink how you go about this.
The best solution for this is to have the parent element of the button have a height of 100% as well, assuming you want your button to have a height of 100%.
td {
height: 100%;
}
.btn {
width: 100%;
height: 100%;
}
<tr>
<td><button class="btn" id="1">1</button></td>
<td><button class="btn" id="2">2</button></td>
<td><button class="btn" id="3">3</button></td>
<td><button class="btn" id="plus">+</button></td>
<td rowspan="2"><button class="btn btn-block" id="equals">=</button></td>
</tr>
i got a one solution if you need your desired results you can adjust the padding of your (td.navigation a class link) through this you will get your results.
apply this css:-
td.navigation a {
color: #837768;
display: block;
font-size: 1.2em;
padding: 14px 5px;
text-align: center;
text-decoration: none;
}
So it's done here with divs, absolute positioning in %, and here's the part you won't like, with a specific height set in pixels. The trouble is, if you use table cells (td) the td's don't have height, and so any element inside will calculate 0 for 100% height.
When we use div's the problem is different. We can make sure they retain their height property, but there's no way to tell the div on the left, "be the same height as the div in the center." At least no way I know of. That being said, it seems like your flash object is the tallest thing, and you could easily set the height of all three div's at a pretty pixel perfect amount. Then stretch the ul navigation list to the height to 100% of the div it's nested within.
There's one other way to do this, that might meet your needs better, I'll detail it at the very bottom.
body,
html {
background: black;
width: 100%;
height: 100%;
padding: 0;

}

The other option you have is to wrap the three columns in a container div, and define a height for that div, then stretch each of the columns to 100% height within that container div.
I am trying to vertically and horizontally center a container, and the content inside using CSS.
The markup looks like this:
<div id="container">
<img src="..someimage.jpg">
<img src="..someverticaldivider">
<form action="action.php">
<input type="text">
.... (other inputs)
</form>
</div>
I need the end result to look like this:
So far, my css looks like this:
#content{
position:absolute;
width: 900px;
left:50%;
top:50%;
height:300px;
margin-top:-150px;
margin-left: -450px;
}
That works fine and if I add a border to #content, I can easily see that it is indeed centered horizontally and vertically.
The problem I am facing is that I do not know the size of the content inside #content. I need to be able to align those elements 2 images and 1 form horizontally and vertically. I have checked out this site for vertically centering, but the problem is that I do not know the size of my content, and the content is not only text.
What is the best way to do this with support for older browsers (IE7 and up)?
You can do it with display:table-cell
fiddle
html
<div id="a">
<div id="b">hello<br/>world</div>
</div>
css
#a {
display: table;
width: 100%;
height: 100%;
}
#b {
text-align:center;
vertical-align: middle;
display: table-cell;
}
html, body {
width: 100%;
height: 100%;
margin: 0;
padding: 0;
}
edit 1
And here is the the final result of the jury
This centers also the content inside the box vertically (image, vertical ruler, form)

I'm trying to give an authoritative answer to this.
Maybe this won't work in mobile browsing (smart phones, iPad etc.). Could anyone check?
Use display: table and display: table-cell in modern browsers which support them to make use of the vertical-align which works with them.
Use positioning with relative measures in some old IE browsers

Could you give a little more info, like why you don't know how big content is? It seems like you want CSS to dynamically change the formatting based on the content you're loading. I don't think that's something CSS is built to do. Javascript would be straight-forward and probably the simplest, but you could do it server-side with something like PHP.
If you give us a little bit more information about the context in which this is being implemented, we'll be able to offer more specific advice about what ways could be used to implement this.
Yo. There's a tendency in placing divs to follow each other vertically, but what i'm trying to accomplish right now is to is basically to place a number of divs (two) inside a parent div like so:
<div id='parent'><div id='onediv'></div> <div id='anotherone'></div> </div>
And i'd like to place 'anotherone' just to the right of 'onediv'. Sadly, float:right is pretty much ruining the layout with the divs popping out of their parent divs and whatnot. Any suggestions are welcome.
Edit: It might be worth noting that the parent div and 'anotherone' has no height elements at all, with 'onediv' planned to be thought as the "height support" div, allowing the contents of 'anotherone' to make the parent div larger at will.
Edit again: Here's the CSS for the specified stuff:
.parent
{
width: 90%;
margin: 0 auto;
border:solid black 1px;
}
.firstchild
{
width: 20%;
margin: 5px;
border: solid black 1px;
height: 180px;
}
.secondchild
{
width: 60%;
border:solid black 1px;
margin: 5px;
}
You can float both inner divs and give the outer div an overflow so that it grows with the inner divs.
Example:
#parent {
overflow: hidden;
}
#parent div {
width: 50%;
float: left;
}
Try this:
<div id="parent">
<div id="onediv" style="float:left;"></div>
<div id="anotherone" style="float:left;"></div>
<div style="clear:both;"></div>
</div>
I think this is what you want (note the re-ordering of DOM elements):
<div id="parent">
<div id="anotherone"></div>
<div id="onediv"></div>
</div>
/*CSS*/
#anotherone{
float:right;
width:50%;
}
#onediv{
float:left;
width:50%;
}
Note, if this is what you want, IE6 will still mess it up. ;-)
You certainly need to specify a width as indicated in #Kevin's answer to get the layout you described, simply specifying float left/right will not have the desired effect. Try specifying the width in pixels rather than a percentage. Failing that or if that's not appropriate for you, I think you possibly need to specify the width of the outer div (through css if you like).
#onediv { float: left; width: 50%; } #anotherone { float: right; width: 50%; }
Just use the <span> tag. Its the equivalent of except it doesn't start a new row.

How can I vertically align elements in a div?
(28 answers)
Closed 3 years ago.
I'm trying to make a small username and password input box.
I would like to ask, how do you vertically align a div?
What I have is:
<div id="Login" class="BlackStrip floatright">
<div id="Username" class="floatleft">Username<br>Password</div>
<div id="Form" class="floatleft">
<form action="" method="post">
<input type="text" border="0"><br>
<input type="password" border="0">
</form>
</div>
</div>
How can I make the div with id Username and Form to vertically align itself to the center? I've tried to put:
vertical-align: middle;
in CSS for the div with id Login, but it doesn't seem to work. Any help would be appreciated.
The best approach in modern browsers is to use flexbox:
#Login {
display: flex;
align-items: center;
}
Some browsers will need vendor prefixes. For older browsers without flexbox support (e.g. IE 9 and lower), you'll need to implement a fallback solution using one of the older methods.

This can be done with 3 lines of CSS and is compatible back to (and including) IE9:

You can vertically align a div in another div. See this example on JSFiddle or consider the example below.
HTML
<div class="outerDiv">
<div class="innerDiv"> My Vertical Div </div>
</div>
CSS
.outerDiv {
display: inline-flex; // <-- This is responsible for vertical alignment
height: 400px;
background-color: red;
color: white;
}
.innerDiv {
margin: auto 5px; // <-- This is responsible for vertical alignment
background-color: green;
}
The .innerDiv's margin must be in this format: margin: auto *px;
[Where, * is your desired value.]
display: inline-flex is supported in the latest (updated/current version) browsers with HTML5 support.
It may not work in Internet Explorer :P :)
Always try to define a height for any vertically aligned div (i.e. innerDiv) to counter compatibility issues.
I'm pretty late to the party, but I came up with this myself and it's one of my favorite quick hacks for vertical alignment. It's crazy simple, and easy to understand what's going on.
You use the :before css attribute to insert a div into the beginning of the parent div, give it display:inline-block and vertical-align:middle and then give those same properties to the child div. Since vertical-align is for alignment along a line, those inline divs will be considered a line.
Make the :before div height:100%, and the child div will automatically follow and align in the middle of a very tall "line."
.parent:before, .child {
display:inline-block;
vertical-align:middle;
}
.parent:before {
content:""; // so that it shows up
height:100%; // so it takes up the full height
}
Here's a fiddle to demonstrate what I'm talking about. The child div can be any height, and you never have to modify its margins/paddings.
And here's a more explanatory fiddle.
If you're not fond of :before, you can always manually put in a div.
<div class="parent">
<div class="before"></div>
<div class="child">
content
</div>
</div>
And then just reassign .parent:before to .parent .before
If you know the height, you can use absolute positioning with a negative margin-top like so:
#Login {
width:400px;
height:400px;
position:absolute;
top:50%;
left:50%;
margin-left:-200px; /* width / -2 */
margin-top:-200px; /* height / -2 */
}
Otherwise, there's no real way to vertically center a div with just CSS
In my firefox and chrome work this:
CSS:
display: flex;
justify-content: center; // vertical align
align-items: center; // horizontal align
I found this site useful: http://www.vanseodesign.com/css/vertical-centering/
This worked for me:
HTML
<div id="parent">
<div id="child">Content here</div>
</div>
CSS
#parent {
padding: 5% 0;
}
#child {
padding: 10% 0;
}
#GáborNagy's comment on another post was the simplest solution I could find and worked like a charm for me, since he brought a jsfiddle I'm copying it here with a small addition:
CSS:
#wrapper {
display: table;
height: 150px;
width: 800px;
border: 1px solid red;
}
#cell {
display: table-cell;
vertical-align: middle;
}
HTML:
<div id="wrapper">
<div id="cell">
<div class="content">
Content goes here
</div>
</div>
</div>
If you wish to also align it horizontally you'd have to add another div "inner-cell" inside the "cell" div, and give it this style:
#inner-cell{
width: 250px;
display: block;
margin: 0 auto;
}
Vertically aligning has always been tricky.
Here I have covered up some method of vertically aligning a div.
http://jsfiddle.net/3puHE/
HTML:
<div style="display:flex;">
<div class="container table">
<div class="tableCell">
<div class="content"><em>Table</em> method</div>
</div>
</div>
<div class="container flex">
<div class="content new"><em>Flex</em> method<br></div>
</div>
<div class="container relative">
<div class="content"><em>Position</em> method</div>
</div>
<div class="container margin">
<div class="content"><em>Margin</em> method</div>
</div>
</div>
CSS:
em{font-style: normal;font-weight: bold;}
.container {
width:200px;height:200px;background:#ccc;
margin: 5px; text-align: center;
}
.content{
width:100px; height: 100px;background:#37a;margin:auto;color: #fff;
}
.table{display: table;}
.table > div{display: table-cell;height: 100%;width: 100%;vertical-align: middle;}
.flex{display: flex;}
.relative{position: relative;}
.relative > div {position: absolute;top: 0;left: 0;right: 0;bottom: 0;}
.margin > div {position:relative; margin-top: 50%;top: -50px;}

Unless the aligned div has fixed height, try using the following CSS to the aligned div:
{
margin: auto;
position: absolute;
top: 0;
left: 0;
bottom: 0;
right: 0;
display: table;
}
I needed to specify min-height
#login
display: flex
align-items: center
justify-content: center
min-height: 16em
if you are using fix height div than you can use padding-top according your design need.
or you can use top:50%. if we are using div than vertical align does not work so we use padding top or position according need.
simplest way to center your div element is to use this class with following properties.
.light {
margin: auto;
width: 50%;
border: 3px solid green;
padding: 10px;
}
Centering the child elements in a div. It works for all screen sizes
#parent {
background-color: red;
height: 160px;
display: flex;
/*vertical-align */
align-items: center;
/*horizontal align*/
justify-content: center;
}
#child {
background-color: orange;
height: 20px;
padding: 10px;
}
<div id="parent">
<div id="child">Content here</div>
</div>
I found a way that works great for me. The next script inserts an invisible image (same as bgcolor or a transparant gif) with height equal to half the size of the white-space on the screen. The effect is a perfect vertical-alignment.
Say you have a header div (height=100) and a footer div (height=50) and the content in the main div that you would like to align has a height of 300:
<script type="text/javascript" charset="utf-8">
var screen = window.innerHeight;
var content = 150 + 300;
var imgheight = ( screen - content) / 2 ;
document.write("<img src='empty.jpg' height='" + imgheight + "'>");
</script>
You place the script just before the content that you want to align!
In my case the content I liked to align was an image (width=95%) with an aspect ratio of 100:85 (width:height).Meaning the height of the image is 85% of it's width. And the Width being 95% of the screenwidth.
I therefore used:
var content = 150 + ( 0.85 * ( 0.95 * window.innerWidth ));
Combine this script with
<body onResize="window.location.href = window.location.href;">
and you have a smooth vertical alignment.
Hope this works for you too!
have you try this one?
.parentdiv {
margin: auto;
position: absolute;
top: 0; left: 0; bottom: 0; right: 0;
height: 300px; // at least you have to specify height
}
hope this helps
divs can't be vertically aligned that way, you can however use margins or position:relative to modify its location.
