Position and resize fixed background image to properly fit div - css

I'm trying to fit a fixed background image properly into a div.
I want the image to
have its left edge be positioned on the divs left edge, even if the div is positioned with margin auto
have a width of exactly the divs size
Both points are problematic.
100% background-size seems to relate to the images original size and not to the div-size. Maybe contain is the correct thing here, but I can't verify that without a solution to problem no 2.
The background-position seems to relate to the complete browser viewport and not to the div.
I have made the image have a proper dimension, so that it should be high enough to cover the visible area when being scrolled over.
Here is a jfiddle: https://jsfiddle.net/417u343f/3/
As you can see, the image is starting more to the left than the start of the div and because of that, it's repeating before the div is at its end.
Thanks for any help, I hope I made my problem clear enough.
<div class="outer">
<div class="test">
<div class="test1">
</div>
<div class="test2">
Text...
</div>
</div>
</div>
css:
div.test {
width: 80%;
margin-left: auto;
margin-right: auto;
height: 250px;
}
div.test1 {
width: 50%;
height:100%;
float:left;
background-image: url('image...');
background-attachment: fixed;
background-size: contain;
}
div.test2 {
width:50%;
float:left;
}

CSS 100% div height with 960 grid

I have been banging my head against the wall trying to figure out this problem and I have looked high and low for the answer and came up with similar results.
Synopsis
The problem is that I am building a website using the 960 grid and have three columns that I want to stretch at 100% at all times. Here is a fiddle for your reference: http://jsfiddle.net/Uec7h/1/
Essentially the html is like so:
<div class="contentWrapper">
<div class="container_12">
<div class="grid_2 leftSide clearfix">
Left sidebar content.
</div>
<div class="grid_7 content">
Lots of content loaded from the server.
</div>
<div class="grid_3 rightSide">
Right sidebar content.
</div>
</div>
</div>
with the CSS being like
html, body {
height: 100%;
}
.content {
height: 100%;
}
.leftSide {
height: 100%;
background-color: #000000;
}
.rightSide {
height: 100%;
background-color: #000000;
}
.contentWrapper {
height: 100%;
}
The fiddle isn't completely accurate to what I am seeing on my local version, but it's close. Seems like the left and right sidebars do not want to expand to 100% no matter what I do.
What I've Tried
Most of the answers I have found on SO have suggested to put height: 100% on the html, body elements and everything should work out fine. Adding this attribute and giving both sidebars height: 100% did work a little bit, but if the content in the middle column gets too big, it stops at a certain point and won't continue to stretch.
I have tried adding the clearfix class that comes with the 960 grid but it didn't seem to help at all.
Question
How do I get the left and right side bars height in the fiddle to be 100% no matter what content is in the middle column?
If you add the following CSS to the sidebar elements it will fill the 100% of the height.
display:block;
height:auto;
position:absolute;
top:0px;
bottom:0px;
If you place the sidebar into a wrapper div with relative positioning, the content section will be again in it's right place...
I would also set padding and margin to 0 for the body.
EDIT:
If you add height: 100% to the .container_12 it will get a real height, and children elements can have a 100% height. Notice that the sidebars will be as height as the window itself, but your content at the middle can be taller than 100%... Fiddle
Dont know the 960 grid, the EDITED solution - using visibility: visible; -
HTML
<div id="box">
<div class="vision"> sdfsdfsd </div>
</div>
CSS
#box {
float: left;
border: 2px solid red;
}
.vision {
width: 300px;
height: 600px;
visibility: visible;
}

Div is not moving nearby divs

I have something like this:
<div class="top">top</div>
<div class="container">
<div class="left">left</div>
<div class="right">right</div>
</div>
<div class="bottom">bottom</div>
Relevant code in jsFiddle
As you can see, between top and bottom divs, there is a div container. I want this div container to move bottom dive as much as is needed (and i don't want it to be a fixed value - that means if, lets say left container will get much higher - the bottom div will be pushed down as well.
How can i do that?
This is a simple seeming problem that ends up being kind of tricky. The above suggestion about position:relative vs. position:absolute are a good first step. After that you need to make some room for the set width right div:
.left {
height: 100%;
min-height: 50px;
border:1px dashed red;
padding-right: 50px; <---
}
Then float your right div in the space you made:
.right {
float:right; <---
width: 50px; (This needs to match the padding-right value above.)
text-align: right;
min-height: 50px;
height: 100%;
border:1px dashed blue;
}
Finally, put the right div before the left div in the html:
<div class="top">top</div>
<div class="container">
<div class="right">right</div>
<div class="left">left</div>
</div>
<div class="bottom">bottom</div>
(Tested in Chrome and IE.)
See: Right div fix width, left div extend to max width?
You can check out a fiddle here: http://jsfiddle.net/x3QfG/1/
Will that work for you?
Right now you're using absolute positions for the left/right div's, so you will always need to know the height in order to position the bottom div correctly. What you want to do is float these instead, then clear the floats in the bottom div. That way the left/right can be as high as their contents, and the bottom div will always appear below.
.bottom {
clear: both;
}
.left {
float: left;
width: 50%;
min-height: 50px;
}
.right {
float: right;
width: 50%;
min-height: 150px;
}
I've modified your jsFiddle accordingly, and made the right div higher to show how the bottom always appears below.
Use floats rather than positioning them absolutely. That will make your architecture very much fluid and flexible.
After you apply necessary float values to your .left and .right, use a clearfix hack to contain your floated elements within the container. Now whenever any of the .left or .right divs increase in height, the bottom div will be pushed down.
Make Container Relative and left and right absolute,and for positioning set width rather than using float.

How can I vertically and horizontally center a DIV?

The behavior of my background image is, that the image is always perfectly centered when I resize the browser window. It gets on the top, left, right and bottom the same "distance" to the edge of my browser window.
The CSS:
background-image: url("ipad.jpg");
background-position: 50% 50%;
background-repeat: no-repeat;
background-size: 563.5px 800px;
I have a div overlaying this image and I would like it to behave in the same way like the background image, so that it is always centered above the background image in the same place.
Is that even possible? And if yes. How?
I hope you understand what I want to achive. :)
Thank you very much for your help. :D
It looks like you're trying to center content horizontally as well as vertically, no matter what size the browser window is. If so, try something like this:
Your HTML:
<div class="outer">
<div class="middle">
<div class="inner">
The content that you want centered.
</div>
</div>
</div>
Your CSS:
/* Vertical and horizontal centering */
.outer {
position:fixed;
top:0; left:0;
width:100%; height:100%;
}
.middle {
height:100%;
display:table;
margin:0 auto;
}
.inner {
vertical-align:middle;
display:table-cell;
}
Good luck!
Edit: Here's an example of the above - http://jsbin.com/aguciw

html div floating and sizing

I want to make a web page that uses 100% of screen space. I have two divs:
1st - menu with fixed width (~250px)
2nd - whats left
The misleading part for me is that the menu div is not in the 2nd div. They both are in a wrapper div (100% width). The problem is that if I write 100% width for the 2nd div, it goes below the menu. If I write less %, I cannot be sure how it will be displayed in smaller resolutions.
Is there is some negative sizing or something? ATM. 1st div floats left and 2nd div float right.
UDPATE: here is some code:
div.main {
width: 100%;
}
div.1st {
width: 250px;
float: left;
}
div.2nd {
width: 100%; #here should be the space that is left in the main div#
float: right;
}
<div class="main">
<div class="1st">menu</div>
<div class="2nd">content</div>
</div>
Problem: content could be as wide as it needs to so if string or objects in it is big enough 2nd div goes below 1st. Menu width is fixed.
UPDATE #2: if i leave content width empty then it will also goes below menu since content is wide enough
Take a look at this Post, there you have the correct solution:
http://www.alistapart.com/articles/holygrail
You could do something like this : http://jsfiddle.net/steweb/78x8y/
markup:
<div id="container">
<div id="left">Width=> 250px, float left</div>
<!-- following div takes automatically the remaining width, no need to declare further css rules -->
<div id="remaining">Width => the remaining space</div>
</div>
css:
#container{
width: 100%;
float:left;
overflow:hidden; /* instead of clearfix div */
}
#left{
float:left;
width:250px;
background:red;
}
#remaining{
overflow: hidden;
background:#DEDEDE;
}
Yes, you can determine the width of absolutely positioned elements by setting left and right. This makes the browser solve the equation in the standard for width. See this demo for an example.

CSS: 3 divs - Resizing 2 outer divs automatically based on width of inner div/text

My problem is best outlined with this schematic/image which outlines how I want it to look:
!
I have a background image and 2 divs for text over the top of it (headline, and intro-text). I also have 2 divs on either side of the headline - these are for the white horizontal stripes.
My issue is that the headline is changeable in a CMS, and I want the horizontal white stripes to automatically fill up the space to the left and to the right of it, regardless of the headline's width.
I can't figure out how to make those 2 horizontal white stripes resize automatically.
Here's my HTML:
<div id="masthead">
<div id="headline-container">
<div id="left-stripe"> </div><div id="headline">{headline}</div><div id="right-stripe"> </div>
</div>
<div class="clear-both"> </div>
<div id="intro-text">{intro_text}</div>
</div>
And here's my CSS - ignore the widths specified for the left-stripe and right-stripe - they're just placeholders:
#masthead {
height: 260px;
}
div#headline-container {
width:960px;
padding:none;
}
div#left-stripe{
float: left;
background-color:#fff;
height: 3px;
width:500px;
display: inline;
}
div#right-stripe{
float: right;
background-color:#fff;
height: 3px;
width:100px;
display: inline;
}
div#headline {
text-align:right;
color: #fff;
font-size: 200%;
float: left;
display: inline;
}
div#intro-text {
text-align: left;
float: right;
width: 300px;
color: #fff;
}
Ideas? Please let me know if I can provide more detail.
I'm a bit too busy to actually test this, but this might give you some direction. i'm not sure the exact effect you're trying to achieve (see comment about finding a live demo someone made).
Regardless, this kind of fluid layout is a bit difficult to achieve reliably with straight CSS. To make it easier I would suggest making the right-stripe a static width.
This CSS solution MIGHT work... no promises.
markup
<div class="container">
<div class="headline-container">
<div class="left-stripe"></div>
<div class="headline">Headline goes here</div>
<div class="right-stripe></div>
</div>
<div class="content"></div>
</div>
CSS
//static width for right stripe
.right-stripe { width: 20px; }
.headline { width: auto; }
.left-stripe { width: auto; }
Using javascript would make it really easy though... here's how i would do it with jQuery. Again, I would make the right-stripe a static width to achieve this effect.
(same markup...)
..
js
var totalWidth = $("#container").width();
var leftWidth = totalWidth - ($("headline").width() + $("right-stripe").width());
$("left-stripe").width(leftWidth);
You can do this dynamically, with jQuery, for example. You take the full width of the 3 div's, drop the size of the inner div and assign dynamically the widths of the 2 outer div's in which the bar should repeat horizontally.
Basically, you will need:
$("#whole-div").width() - $("#inner-div").width() for the outer div's total width. Then, depending on your positioning of the inner-div, you assign values for the outer div's.
For example: whole div has 1000px, inner div has 200px and inner div is positioned 600px left. You will then assign 600px to the left div ($("#whole-div").width() - $("#inner-div").css('left')) and 200px for the right div ($("#whole-div").width() - $("#inner-div").css('left') - $("#inner-div").width()). Of course, you will then set a background-repeat property on the outer div so that the image repeats.
Hope that helps!
UPDATE CSS only fluid solution: http://jsfiddle.net/SebastianPataneMasuelli/XnvYw/1/
it uses the same background image twice, on #masthead and on #headline-container. except ton headline container the background is offset to match its left position relative to its parent element. then we only need one div.line behind it, which gets covered by the background image under the headline and copy, giving the illusion of a seamless image.
do you mean like this?: http://jsfiddle.net/SebastianPataneMasuelli/XnvYw/
