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

So, I have a few divs that i want to center.
I'm currently using this css code on something i call a "container div" - you've most likely heard this "container" thingy before.
#container {
margin: auto;
width: 75%;
margin-top: 100px;
}
Although this does not seem to center the divs when resizing the window; If I resize the window, the divs will follow slowly and by that -move further away from the center.
Fiddle - https://jsfiddle.net/kud3f01n/
What is causing the divs to behave like this?
As verified in your example, I've found that you made those blocks design by using margins(negative and high range values). Hence even you are giving main container width 75% or any other still it will overflow from the parent div. And this kind of CSS will create critical issues in smaller devices.
Suggestion: Try to avoid this type of CSS. And if you need this type alignment and it has t be work in responsive also you can some third party plugins such as masonry.js etc.,
Try this
#container {
height:50px;
width:50px;
position:absolute;
left:50%;
top:50%;
margin: 0 auto;
}
I have some fixed pixel divs on the top and bottom and a responsive one in the middle. How can I prevent it from going into the top div when the screen is adjusted small?
Here is a working example to illustrate the problem. I want to be able to make the browser small and not have the black box go into the red. While maintaining the responsiveness.
<div style="position:relative; height:100px; width:100%; background:red;"/>
http://jsfiddle.net/RHZLr
I would forget absolute positioning in this case. Make all the boxes relatively positioned, and use margins to position the black box as you please. This way responsiveness works as desired.
Working Fiddle
#blackBox{
margin: 0 auto;
height: 200px;
width: 400px;
background: black;
}
Instead of using width:100% try using a fixed width. Fixed widths don't move so you won't have to worry about them invading other divs.
Also!
It might behoove you to use CSS media queries to give the divs a fixed (non moving) position once the screen gets to a certain size.
e.x.
#div1{
position:relative;
left:25%;
width:50%;
}
#media screen and (max-width:600px){
#div1{
width:500px;
height:500px;
}
}

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.
I want to create css layout with 3 fixed columns like you can see on image, but the most important thing that left(1) and right(3) columns must hide on low resolution monitor (or when windows is not full size).
On stackowerflow I found something similar, but the left and right columns is not fixed size. and also text on this example "crash" center design on low resolution window (center column goes down!).
jsfiddle.net/XMg2h/418/
There are certainly other ways to approach this out there, but here's my quick solution, which basically involves juggling some relative and absolute positioning. Here's the styling I used to get (hopefully?) the behaviour you were looking for (HTML remained the same):
.example{
width:300px;
margin:0 auto;
position:relative;
}
.example div{
position:absolute;
width:50px;
top:0;
height:300px;
}
.example div:first-child{
left:-50px;
}
.example div:last-child{
right:-50px;
}
.example div.center{
width:300px;
right:0;
}
The negative right/left of the divs must correspond to the magnitude of each side column's width. Here's a JSFiddle example based on the one you supplied. You'll note that if you resize the window, it will keep the central div, well, centered (up to the point where the window becomes smaller than the central div, after which it is aligned to the left).
I hope this is what you were looking for! If it wasn't, let me know and I'll be happy to try to help you further. Good luck!
You can use media queries:
#media (max-width: 600px) {
.example div:first-child, /* <- and add some classes to your divs */
.example div:last-child{
display: none;
}
}
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.
