I just want the div to be in the center of the page, equal spacing from top to bottom and I need to use percents because the div content varies. I tried bottom:50% but this does not work.
Thanks for the answers! Mine's a little different and it is my mistake for not adding this, visit my blog to view the issue.
Hey everyone, thanks for using your time to answer such a stupid question, but I found that the easiest way is to just use padding:
padding-top:X%;
padding-bottom:X%;
Then just mess with it to see what your result is. If you have anything better PLEASE DO SHARE because this is obviously probablly not the most reliable.
Your answer of using percentages in padding doesn't work in all situations. This is because padding percentages are based on the width of the element you are adding padding to and not the height of it. Plus, it's not at all based on the container you want the element centered within. So if you were to decrease the width of your browser window, your DIV would move to a location that is no longer centered within the browser window because the width of the DIV has changed, causing the percentage value of your padding to change as well.
To truly center your DIV no matter the browser window dimensions, the code below should help tremendously:
.div {
position: fixed;
top: 50%;
left: 50%;
transform: translate(-50%, -50%);
}
#mydiv {
position:absolute;
top:20%; bottom:20%
}
See also Understanding Vertical Align.
vertical-align:center for vertically aligning
then text-align:center for horizontal
#div{
position:absolute;
top:0;
bottom:0;
left:0;
right:0;
height:100px;
width:100px;
}
this code aligns either bottom to top,or left to right but you have to set width and height.
Or use this:
#div{
display:flex;
align-items:center;
}

I'm working on a mobile version of my website, and I'm having trouble vertically-centering two divs. Since it is a mobile site, my css needs to work on any type of screen resolution, so this is where I'm having the problem. Also, different images will be used depending on what page you are on, so the resolution of the image is not static either. I need a way to center both my image div and text div no matter their height or width.
I've made a fiddle here to start out with. As you can see, I chose the green area to be the "screen" for the phone, and I want both the picture to center vertically, and the text to be on top of the picture and center vertically as well. Any help?
What I have so far... (in my jsfiddle)
HTML:
<div id = "screen">
<div class = "overlay" id = "picture"><img src = "http://www.startingtofeelit.com/wp-content/uploads/2013/10/Tennis-Mean-Streets.jpg" /></div>
<div class = "overlay" id = "text">This is where the text would appear</div>
CSS:
#screen {
width:360px;
height:640px;
background-color:#0f0;
position:relative;
overflow:hidden;
display:table-cell;
vertical-align:middle;
}
.overlay {
position:absolute;
top:0;
left:0;
}
#picture {
}
#picture img{
width:100%;
}
#text {
background-color:#000;
width:100%;
opacity:0.5;
color:#fff;
}
For vertically centering you can set margin top/bottom to auto.
If I understand where you want the text, this should work.
Html
<div id = "screen">
<div class = "overlay" id = "text">This is where the text would appear</div>
<div class = "overlay" id = "picture"><img src = "http://www.startingtofeelit.com/wp-content/uploads/2013/10/Tennis-Mean-Streets.jpg" /></div>
</div>
and css
#screen {
width:360px;
height:640px;
background-color:#0f0;
position:relative;
overflow:hidden;
display:table-cell;
vertical-align:middle;
}
#picture {
margin: 0 auto;
}
#picture img{
width:100%;
}
#text {
position: absolute;
top:50%;
background-color:#000;
width:100%;
opacity:0.5;
color:#fff;
}
So it doesn't seem like there is a pure css way to do it, so I ended up using jQuery instead. I made a fiddle in case you want to see how I did it, but the jist of it was this.
On document load, find any item with class "overlay" and apply a negative margin-top of half it's height to center it. Because it already has a position of absolute and top:50%, this will vertically center the item.
$(document).ready(function(){
$(".overlay").each(function(){
$(this).css("margin-top", $(this)[0].scrollHeight/2*-1);
});
});
It's pretty simple, and I wish there was a way to do it in pure css, but this way works as well. Thanks for all the help.
After the discussion in the comments I've determined this question is not nearly thought out well enough to attempt to answer and so this will stay simply in hopes that someone else that finds this page is helped by the answer
:::Initial answer:::
This question is easily much more difficult than you've made it seem. If it's a matter of fitting the image to the viewport of the device there is no single css solution and a javascript solution will be needed.
Let me explain, if the image is much taller than it is wide then to fit the image to the screen you'd want to set the height to something like 90% of the height (give some padding for the text etc). however since the image is variable size if the width is the greater value you'll want the width to something like 90%. Herein lay the problem, you wont want both the height and the width of the image to be 90% as that would distort the image. So there will need to be some javascript to flop around some classes here.
After that the css gets a bit hairy also, if you're looking for an overlay to display the same based on any position the user clicks on an image (assuming this is a sort of gallery) rather than an absolute positioned item at the top and left of the document you'll want a position: fixed; element which is positioned on the viewport.
All described before would need a bit of javascript again because there is no easy way to center something that is fixed without using negative margins of half its width/height.
An example of such a thing is here:
http://jsfiddle.net/5hHMa/2/
Here we have the css for the very fixed case which you have presented.
.overlay {
position:fixed;
top:50%;
left:50%;
margin-top: -150px;
margin-left: -150px;
}
#picture img{
width: 300px;
}
#text {
background-color:#000;
opacity:0.5;
color:#fff;
}
Ideally what you would do is instead of using a fixed value for the margins and width as I have you would determine these values and set them using javascript.
It is hard to form a complete solution for your problem with the limited information given, however hopefully this gives you a push in the correct direction.
So I know this is another centering question but I've been roaming around Google and SO for a couple days now without a solution so I'll ask now.
What I'm trying to do is horizontally center a fluid section element with a max width that has absolutely positioned elements inside it. The problem is, as you can see in my jsFiddle, the margins take up 50% of the available space with the other 50% used by the section. What I would like to do is keep the section perfectly centered but make the margins get smaller as the browser window closes in while keeping the section from re-sizing until the edges of the window gets to it.
I'd like to keep from using any table, table-cell solution because I read on CSS-Tricks that absolutely positioning elements inside table cells can be a real pain.
Edit Basically, the goal is to have the content take up as much space as possible without resizing until the view port width forces the content to be responsive.
Thank you for any bump in the right direction.
HTML:
<section id="wrapper">
<section id="content">
<p>Absolutely positioned imgs, btns, etc. go in here</p>
</section>
</section>
CSS:
#wrapper {
position:absolute;
width:50%;
height:300px;
margin-left:25%;
margin-right:25%;
outline:1px solid red;
}
#content {
position:absolute;
width:100%;
height:100%;
max-width:500px;
background:rgb(225, 112, 75);
}
You can use
#content {
display:inline-block;
text-align:center;
}
to center your elements that will have a display:inline-block; property too.
EDIT: Now that I've better read your question, you can also use
#content {
margin:0 25%;
}
to center your second section.
here's your fiddle updated. As you can see by this fiddle everything is centered AND responsive now.
EDIT-2: Maybe you want to add some media query to reach your goal. Just add something like this at the end of your CSS file:
#media screen and (max-width:720px){
#content{width:100%; margin:0px;}
}
this says that when screen reaches the width of 720 and under, #content (and every ID/CLASS you put in there) will behave as declared.
NOTE that #media queries are not crossbrowser, you may want to add a script to make them work on every browser, I find respond.js a nice tool to do this job.
Also note that the #media queries must be placed at least under the default properties that you are about to change on screen resizing, that is why is suggested to add them at the bottom of your css file.
HERE is another fiddle with media applied (just try to resize the box to see the effect)
I wonder if this is what you were looking for: jsfiddle
I changed your wrapper to this:
#wrapper {
position: fixed;
top: 50%;
left: 50%;
margin-top: -150px;
margin-left: -200px;
width:400px;
height:300px;
outline:1px solid red;
}
So that your div now sits in the middle of the screen
I want to create a layout where I want to display an image to the left and content on the right. The image should stay constant when the content scrolls.
The css I'm using:
<style type="text/css">
#page-container
{
margin:auto;
width:900px;
background-color:Black;
}
#header
{
height:150px;
width:650px;
}
#main-image
{
float:left;
width:250px;
height:500px;
background-image:url('../images/main-image.png');
position:fixed;
}
#content
{
margin-left:250px;
padding:10px;
height:250px;
width:630px;
background-color:Teal;
}
</style>
The HTML:
<div id="page-container">
<div id="header"><img src="someimagelink" alt="" /></div>
<div id="main-image"></div>
<div id="content"></div>
</div>
Alot of time on this site and I have understood that background-attachment:fixed positions the image in the entire viewport and not the element it is applied to.
My question is how do I go about creating that kind of layout?
I do not want to give that image as a background image, as if the window is resized, it might get hidden. I want scrollbars to appear if the window size is less than 900px( my page width) so that the image can be viewed at all times.
That happens with this code, however I would like the image to start at my element instead.
How do I go about doing this??
Thanks in Advance :)
Edited:
I took the advice and added a position:fixed property to #main-image. Using the HTML and CSS as shown above.
Now, I also want to fix the header so that it does not move. Basically, only my content section should scroll.
However, if I add a position:fixed to the header, my #main-image and #content now sit on top of my header.
If I add a margin-top:150px (since my header height is 150px) to the #main-image, it works fine and moves down appropriately.
However if I add a margin-top:150px to the #content, my header moves down by 150px and still sits on top of my #content.
Can someone please explain why this is happening?
Thanks in Advance :)
Take a look at this link:
http://www.barelyfitz.com/screencast/html-training/css/positioning/
You can learn how to position Div's with it.
This will solve your problem:
#main-image {position:fixed;}
EDIT:
I'm not sure of what caused your problem but here is the solution:
#content{
position:relative;
top:150px;
}
My Guess:
I think that happened because when using position:fixed those 2 div's were positioned relative to the the browser window, while the other one was relative to the document itself.
In this link you will see more about positioning and you can test some of these features related to the position property:
http://www.w3schools.com/cssref/pr_class_position.asp
About the fact that one div was positioned over another, you should search for the 'z-index' property. Firefox has a 3D mode so you can see this more clearly:
http://www.addictivetips.com/internet-tips/browse-internet-in-3d-using-mozilla-firefox-11-tip/
Set a min-width on html and body.
Have you tried setting your #page-container to relative and your #main-image container to absolute and setting the position using top, bottom, etc. Then you should also be able to float your #content container to the right.
You see tons of sites with their content very nicely centered, like dribbble.com for example. Even when the window is resized, the content stays centered and when it hits against the side of the page, stops.
I would really like to get this behavior on my website but I'm not really sure how to go about the CSS to make this happen... I'm aware of the position property and using percentages for the left/right positioning but it doesn't seem to be quite that simple.
Can someone help me figure out how to do something like this?
The standard practice is to have a div that wraps your centered content, such as...
<div id="container">
...everything you want to center
</div>
And the in your CSS:
#container {
width: 970px;
margin: 0 auto; /*first value the margin for top and bottom, auto puts automatic margins in the left and right to center the content*/
}
I'm aware of the position property and using percentages for the left/right positioning but it doesn't seem to be quite that simple.
It's simpler.
selector-that-matches-a-container {
width: <some length>
margin: auto;
}
Maybe with this CSS:
.content {
position:absolute;
left:100px;
right:100px;
}
We have a login page that is designed to have a 200px-high DIV vertically centered in the middle of the page. That is, it creates a 200 pixel blue band left edge to right edge (with form elements in it) that ideally should remain vertically centered in the viewport no matter how the browser window is resized.
This must be a CSS solution.
So let's say here's some sample markup:
<body>
<div id="mainDiv">
<div id="centerDiv" style="height:200px;background-color:blue;color:white">
Center this baby vertically in the #mainDiv, please!
</div>
</div>
</body>
Assume that my CSS dictates that the #mainDiv is stretched to cover the viewport top and bottom, which is easy enough to do. Are there CSS rules that I can apply to any of the elements or the page that will reliably and cross-browser (incl. IE6) vertically center #centerDiv? In a perfect world we should just be able to say
#centerDiv {
margin: auto 0;
}
And even in an OK world we should be able to address this issue with a few styles. But to quote Ving Rhames' character from Pulp Fiction, We're pretty %&#!ing far from OK.
I've looked at the solutions offered in Related Questions and scoured the Web. Nothing I can find really works 100%. Maybe this is unsolvable, but I thought I'd give the collective brains here the problem and see if I can get lucky. Thanks in advance.
If you have a fixed height, you can do it. Give the child div a top of 50% and a margin-top of -100px (or vice-versa) and you should be set.
if height unknown:
http://jsfiddle.net/Limitlessisa/a7xw6b2c/
.centerdiv{
background:red;
position:absolute;
left: 50%;
top: 50%;
transform: translate(-50%, -50%);
}
For true automatic positioning in the center, the inner DIV would need to know the boundaries of the containing DIV. If your container does not have hard boundaries, there is no way for the inner DIV to calculate its own position automatically. It simply has no frame of reference.
The closest I think you can make it with a simple CSS solution is this:
#mainDiv
{
border: 1px dashed #000000;
}
#centerDiv
{
margin: 33% auto;
height: 200px;
}
