center div within 100% width div - css

I am trying the Blueprint CSS framework, and am having a hard time figuring out how to do the overall layout.
It seems Blueprint (as far as I have understood it so far) makes you use a set page width at 950px. I guess you could change that with some modification, but in any case there has to be some width, so that's fine. The problem is, even if I want the main content of the page to be 950px wide, I want 100% wide headers and footers.
So I have placed a header and a footer outside the main "container" div that's 950px wide. I set the header div to 100%. And then I have a "headerContent" div inside it (containing menu, logo, etc), which has a 950px width (span-24 in Blueprint terms). But I want the headerContent div to be centered within the header div.
I have always used the "margin: 0 auto" trick to do this, but for some reason it doesn't work at all now.
Here's the html:
<div id="header" class="blueheader">
<div id="headerContent" class="span-24">
<div id="logo" class="span-6">
<a href="/">
<img src="/images/expertinfo.png" width="230" height="62" />
</a>
</div>
<div id="menucontainer" class="span-14"><ul id="menu"><li>
<a href='/Services/Index'>TJĂ„NSTER</a></li>
<li>
<a href='/About/References'>KUNDER</a></li>
<li>
<a href='/About'>OM OSS</a></li>
<li>
<a href='/About/Contact'>KONTAKT</a></li>
</ul></div>
<div id="logindisplay" class="span-2">
Logga in
</div>
</div>
</div>
And here's the css for header and headercontent:
#headerContent
{
overflow: auto;
zoom: 1;
margin: 0 auto;
}
#header
{
width: 100%;
position: relative;
margin-bottom: 0px;
color: #000;
margin-bottom: 0px;
overflow: auto;
zoom: 1;
}
The overflow and zoom part is just another trick I read about to avoid having to use empty divs to clear containing divs, and I tried without them with no luck, so they have nothing to do with the problem.
Any ideas what I'm doing wrong?

You need to set a width the the #headerContent because without it defaults to width:100% if you place a 950px width to the div, you should be fine.

Found the answer: you shouldn't use span-24 on the headerContent apparently in the Blueprint framework, but rather the container class. Here's what worked:
<div id="header" class="blueheader">
<div id="headerContent" class="container">
<div id="logo" class="span-6">
<a href="#Url.Action("Index", "Home")">
<img src="/images/expertinfo.png" width="230" height="62" />
</a>
</div>
<div id="menucontainer" class="span-14">#Html.Raw(Html.Menu())</div>
<div id="logindisplay" class="span-2">
#Html.Partial("_LogOnPartial")
</div>
</div>
</div>
I cannot say I understand exactly why it didn't work before, and that worries me, because I am trying this framework to simplify layout, but this made it harder to understand. As far as I could see it should have worked with the first code too...

how can I clip an <img> inside a <blockquote>

I am trying to limit the horizontal size of whatever I load in a blockquote (I do not control that content in the blockquote so I know it's going to screw up my layout). Here is a reduced testcase of what the page layout looks like:
<html>
<body>
<div style="width: 800px; background-color: #ff0000;">
<div style="display: table;">
<div style="display: table-row;">
<blockquote style="overflow:hidden;">
<div style="width: 1000px; height: 400px;background-color: #00ff00;"></div>
</blockquote>
</div>
</div>
</div>
</body>
</html>
The size of the blockquote is implicitely set through a width on one of its parent elements and a table container is used to layout the blockquote itself.
Now, if you try to copy/paste the above html into a test.html file, you will see the entire inner div displayed as blue, beyond the boundaries of the red background. I would like to make sure it gets cliped at the background boundaries.
The question is then: is there a way to do this without changing the structure of the html layout and without having to set again an explicit width on the blockquote itself (I cannot do the latter because I do not know the real size of the blockquote in the real layout because there are other elements within the outer div that take an unknown amount of horizontal space) ?
EDIT
Earlier, I naively tried the following. I added an extra column in the table to illustrate the fact that I really do not know how much space the other elements in the table will suck up.
<html>
<body>
<div style="width: 800px; background-color: #ff0000;">
<div style="display: table;">
<div style="display: table-row;">
<div style="display: table-cell;">
<blockquote style="overflow:hidden;" id="inner">
<div style="width: 1000px; height: 400px;background-color: #00ff00;"></div>
</blockquote>
</div>
<div style="display: table-cell;">
<div style="width:100px; background-color:#0000ff; height: 300px;"></div>
</div>
</div>
</div>
</div>
<script>
var width = document.getElementById('inner').parentNode.offsetWidth;
console.log(width);
</script>
</body>
</html>
In order for overflow: hidden; to work you have to set the dimensions of the element explicitly. So, yes, sorry, you have to specify the width on blockquote.
If you are allowed to, you can use javascript to determine the width of the parent element which has a set width and then set the width of the blockquote accordingly.
Here's an example of how that might work, using your current markup:
var root = document.getElementsByTagName('div')[0],
block = document.getElementsByTagName('blockquote'),
i;
for (i = 0; i < block.length; i += 1) {
block[i].style.maxWidth = root.style.width;
}
Demo
However, this would be vastly improved if you were to give the div that's got the set width a class name or id. Check out this fiddle to see how that would work.

responsive images inside a full width div

I have this markup:
<div class="girls" style="text-align:center; margin-top:100px">
<img src="images/1.png" />
<img src="images/2.png" />
<img src="images/3.png" />
<img src="images/4.png" />
and this css (I'm using Twitter Bootstrap) :
img {
height: auto;
max-width: 100%;
vertical-align: middle;
border: 0;
-ms-interpolation-mode: bicubic;
}
The images have equal width and height and are displayed inline.
On my resolution are ok, fit the entire width (1366px), but on lower resolutions the images don't fit.
So, I need to keep the proportions on every screen resolution ( lower than 1366px in my case)
I've found this picturefill
Which I think is helpful for me, but I'm thinking that it's a simpler solution for my case because I have 4 images which I need to display them horizontally and make them scale on every resolution.
Thanks!
You can set the style width attribute of the images to 25%, without specifying height. That's gonna work if you're always putting 4 images, they have the same width between them and your container div is always at 100%.

If you are using Twitter Bootstrap, then use markup properly like in Twitter Bootstrap documentation:
<div class="row-fluid">
<div class="span3">
<img src="http://placehold.it/350x400"/>
</div>
<div class="span3">
<img src="http://placehold.it/350x400"/>
</div>
<div class="span3">
<img src="http://placehold.it/350x400"/>
</div>
<div class="span3">
<img src="http://placehold.it/350x400"/>
</div>

Padding of div in another div affects other elements

Hello I'm trying to create a navigation bar which is made up of several div containers in one big navigation div.
I'm not sure if my approach is right but I tried to do it like this:
<div id="navigation">
<div class="innen">
<div class="logo">
<img class= "logo" src="logo.png" title="Logo"/>
</div>
<div id="bar">
<!-- Navigation Items are in here --!>
</div>
<div id="gamecard">
<!-- Another right floated Element !-->
</div>
</div>
<div class="unten">
<p>You are here: Main</p>
</div>
</div>
I wanted to push down the bar div to meet the height of the image by using top padding:
#bar{
padding-top: 80px;
}
But now it moves the down gamecard container too. How can I prevent this from happening?
I also added a jfiddle:
http://jsfiddle.net/Cv4p2/
try using position:absolute
<div id="bar" style="position:absolute; padding: 80px 0 0 0">
</div>
Padding is intended to add a cushion inside the container in which you implement it. It appears that you would benefit from using margin. You should replace "padding-top: 80px;" with "margin-top: 80px;" and you would achieve the desired effect.

Bootstrap Element 100% Width

I want to create alternating 100% colored blocks. An "ideal" situation is illustrated as an attachment, as well as the current situation.
Desired setup:
Currently:
My first idea was to create an div class, give it a background color, and give it 100% width.
.block {
width: 100%;
background: #fff;
}
However, you can see that this obviously doesn't work. It's confined to a container area. I tried to close the container and that didn't work either.
The container class is intentionally not 100% width. It is different fixed widths depending on the width of the viewport.
If you want to work with the full width of the screen, use .container-fluid:
Bootstrap 3:
<body>
<div class="container-fluid">
<div class="row">
<div class="col-lg-6"></div>
<div class="col-lg-6"></div>
</div>
<div class="row">
<div class="col-lg-8"></div>
<div class="col-lg-4"></div>
</div>
<div class="row">
<div class="col-lg-12"></div>
</div>
</div>
</body>
Bootstrap 2:
<body>
<div class="row">
<div class="span6"></div>
<div class="span6"></div>
</div>
<div class="row">
<div class="span8"></div>
<div class="span4"></div>
</div>
<div class="row">
<div class="span12"></div>
</div>
</body>
QUICK ANSWER
Use multiple NOT NESTED .containers
Wrap those .containers you want to have a full-width background in a div
Add a CSS background to the wrapping div
Fiddles: Simple: https://jsfiddle.net/vLhc35k4/ , Container borders: https://jsfiddle.net/vLhc35k4/1/
HTML:
<div class="container">
<h2>Section 1</h2>
</div>
<div class="specialBackground">
<div class="container">
<h2>Section 2</h2>
</div>
</div>
CSS: .specialBackground{ background-color: gold; /*replace with own background settings*/ }
FURTHER INFO
DON'T USE NESTED CONTAINERS
Many people will (wrongly) suggest, that you should use nested containers. Well, you should NOT.
They are not ment to be nested. (See to "Containers" section in the docs)
HOW IT WORKS
div is a block element, which by default spans to the full width of a document body - there is the full-width feature. It also has a height of it's content (if you don't specify otherwise).
The bootstrap containers are not required to be direct children of a body, they are just containers with some padding and possibly some screen-width-variable fixed widths.
If a basic grid .container has some fixed width it is also auto-centered horizontally.
So there is no difference whether you put it as a:
Direct child of a body
Direct child of a basic div that is a direct child of a body.
By "basic" div I mean div that does not have a CSS altering his border, padding, dimensions, position or content size. Really just a HTML element with display: block; CSS and possibly background.
But of course setting vertical-like CSS (height, padding-top, ...) should not break the bootstrap grid :-)
Bootstrap itself is using the same approach
...All over it's own website and in it's "JUMBOTRON" example:
http://getbootstrap.com/examples/jumbotron/
This is how you can achieve your desired setup with Bootstrap 3:
<div class="container-fluid">
<div class="row"> <!-- Give this div your desired background color -->
<div class="container">
<div class="row">
<div class="col-md-12">
... your content here ...
</div>
</div>
</div>
</div>
</div>
The container-fluid part makes sure that you can change the background over the full width. The container part makes sure that your content is still wrapped in a fixed width.
This approach works, but personally I don't like all the nesting. However, I haven't found a better solution so far.
There is a workaround using vw. Is useful when you can't create a new fluid container.
This, inside a classic 'container' div will be full size.
.row-full{
width: 100vw;
position: relative;
margin-left: -50vw;
left: 50%;
}
After this there is the sidebar problem (thanks to #Typhlosaurus), solved with this js function, calling it on document load and resize:
function full_row_resize(){
var body_width = $('body').width();
$('.row-full').css('width', (body_width));
$('.row-full').css('margin-left', ('-'+(body_width/2)+'px'));
return false;
}
In bootstrap 4, you can use 'w-100' class (w as width, and 100 as 100%)
You can find documentation here:
https://getbootstrap.com/docs/4.0/utilities/sizing/
If you can't change the HTML layout:
.full-width {
width: 100vw;
margin-left: -50vw;
left: 50%;
}
<div class="container">
<div class="row">
<div class="col-xs-12">a</div>
<div class="col-xs-12">b</div>
<div class="col-xs-12 full-width">c</div>
<div class="col-xs-12">d</div>
</div>
</div>
Demo: http://www.bootply.com/tVkNyWJxA6
Sometimes it's not possible to close the content container.
The solution we are using is a bit different but prevent a overflow because of the
firefox scrollbar size!
.full-width {
margin-top: 15px;
margin-bottom: 15px;
position: relative;
width: calc(100vw - 10px);
margin-left: calc(-50vw + 5px);
left: 50%;
}
Here is a example: https://jsfiddle.net/RubbelDeKatz/wvt9253q
Instead of
style="width:100%"
try using
class="col-xs-12"
it will save you 1 character :)
Sorry, should have asked for your css as well. As is, basically what you need to look at is giving your container div the style .container { width: 100%; } in your css and then the enclosed divs will inherit this as long as you don't give them their own width. You were also missing a few closing tags, and the </center> closes a <center> without it ever being open, at least in this section of code. I wasn't sure if you wanted the image in the same div that contains your content or separate, so I created two examples. I changed the width of the img to 100px simply because jsfiddle offers a small viewing area. Let me know if it's not what you're looking for.
content and image separate: http://jsfiddle.net/QvqKS/2/
content and image in same div (img floated left): http://jsfiddle.net/QvqKS/3/
I would use two separate 'container' div as below:
<div class="container">
/* normal*/
</div>
<div class="container-fluid">
/*full width container*/
</div>
Bare in mind that container-fluid does not follow your breakpoints and it is a full width container.
I'd wonder why someone would try to "override" the container width, since its purpose is to keep its content with some padding, but I had a similar situation (that's why I wanted to share my solution, even though there're answers).
In my situation, I wanted to have all content (of all pages) rendered inside a container, so this was the piece of code from my _Layout.cshtml:
<div id="body">
#RenderSection("featured", required: false)
<section class="content-wrapper main-content clear-fix">
<div class="container">
#RenderBody()
</div>
</section>
</div>
In my Home Index page, I had a background header image I'd like to fill the whole screen width, so the solution was to make the Index.cshtml like this:
#section featured {
<!-- This content will be rendered outside the "container div" -->
<div class="intro-header">
<div class="container">SOME CONTENT WITH A NICE BACKGROUND</div>
</div>
}
<!-- The content below will be rendered INSIDE the "container div" -->
<div class="content-section-b">
<div class="container">
<div class="row">
MORE CONTENT
</div>
</div>
</div>
I think this is better than trying to make workarounds, since sections are made with the purpose of allowing (or forcing) views to dynamically replace some content in the layout.
Though people have mentioned that you will need to use .container-fluid in this case but you will also have to remove the padding from bootstrap.
The following answer is not exactly optimal by any measure, but I needed something that maintains its position within the container whilst it stretches the inner div fully.
https://jsfiddle.net/fah5axm5/
$(function() {
$(window).on('load resize', ppaFullWidth);
function ppaFullWidth() {
var $elements = $('[data-ppa-full-width="true"]');
$.each( $elements, function( key, item ) {
var $el = $(this);
var $container = $el.closest('.container');
var margin = parseInt($container.css('margin-left'), 10);
var padding = parseInt($container.css('padding-left'), 10)
var offset = margin + padding;
$el.css({
position: "relative",
left: -offset,
"box-sizing": "border-box",
width: $(window).width(),
"padding-left": offset + "px",
"padding-right": offset + "px"
});
});
}
});
This must work (Mobile phone as well as Desktop screen):
class: alignfull and class: img-fluid will do the magic.
<div class="alignfull">
<img class="img-fluid" style="background-size: cover;
background-position: center ;
background-repeat: no-repeat;
height: auto;
min-width: 100%;
width: -moz-available; "
src="{{ $image->image }}" alt="An image">
</div>

Floating divs with fixed top position

I have an HTML "toolbar" containing a number of widgets arranged horizontally. Each item is represented by a div in the source document:
<div id="widget1" />
<div id="widget2" />
<div id="widget3" />
I position the divs using float: left. The problem is that I also want them to be pinned to the top of the toolbar so that they don't wrap around if the user reduces the width of the window. Instead, I just want them to overflow horizontally (with the overflow hidden) so that the behavior is like that of a real toolbar.
In other words, I want something like position: fixed but only for the vertical coordinate. Horizontally they should be positioned one after another in a row. Is there any way to do this with CSS?
Update Here's the real HTML I'm using. The divss with class="row" are the ones that should appear as widgets in the toolbar, arranged horizontally in a single row.
<div class="row" id="titleRow">
<span class="item"> <img src="../images/logo.png" height="26" /> </span>
<span class="item" id="title">Title</span>
<span class="item" id="close" onclick="window.close();"> close </span>
</div>
<div class="row" id="menuRow">
<span class="item"> <ul id="menu"></ul> </span>
</div>
<div class="row" id="searchRow">
</div>
<div class="row" id="pageRow">
<span class="item" id="page-related-data"> Page-related data: </span>
</div>
Rather than float: left; try display: inline-block; vertical-align: top;. Then set white-space: nowrap; and overflow: hidden; on the parent element. See http://jsfiddle.net/rt9sS/1/ for an example.
Note inline-block has some issues. It's white space aware (so white space around elements in the HTML will be visible in the document). It also has limited support in IE6/7, although you can work around that by giving the element layout, e.g. .oldie .widget { display:inline; zoom:1; }. See http://www.quirksmode.org/css/display.html#inlineblock for more.
I know this is an old question, wanted to add a simple jquery answer for those that run across it.
$(window).scroll(function(){
$("#keep-in-place").css("top",$(document).scrollTop()+"px");
});
To make higher or lower on page simply add to $(document).scrollTop()
Works for me
