I have created a Bootstrap carousel, and I am using custom css to define a background image for each of the three slides. For some reason, the background image is not appearing on the first slide, although the background images for slides 2 and 3 are appearing ok. I can't work out what is wrong. I think it may be something to do with the active class being applied just to the first slide?? Here is the HTML and CSS for the first slide, the carousel is called myCarousel, thanks:
HTML:
<!-- class item means item in carousel -->
<div id="slide1" class="item active">
<!--
<img src="http://placehold.it/1200x500">
-->
<h1>HELLO THERE</h1>
<div class="carousel-caption">
<h4>High Quality Domain Names</h4>
<p>Domains that can help your business marketing</p>
</div> <!-- close carousel-caption -->
</div> <!-- close slide1 -->
CSS:
#myCarousel .item { height: 400px; }
<!-- top left is the background position of the image, no repeat because we don't want the background image repeating -->
#slide1 {
background: url('images/carousel_medium_01.jpg') top center no- repeat;
}
Instead of putting your code directly on the <div class="item"> I suggest to make a nested div (replacing the image) and apply a height, width and background-image properties there instead. Like this:
HTML
<div class="carousel-inner" role="listbox">
<div class="item">
<div class="item-custom first"></div>
</div>
<div class="item">
<div class="item-custom second"></div>
</div>
<div class="item active">
<div class="item-custom third"></div>
</div>
</div>
CSS
.item-custom {
height: 100%;
width: 100%;
}
Then for your .first, .second, and .third classes you can add the background-images you want. That should get you going in the right direction. Hope that helps.
The code above is loading the placeholder background image, but it is only visible behind the h1 element due to the lack of the parent #myCarousel div.
The CSS is looking for the parent div on which to apply the explicit height and width.
Try adding the parent div:
<!-- class item means item in carousel -->
<div id="myCarousel">
<div id="slide1" class="item active">
<!--<img src="http://placehold.it/1200x500">-->
<h1>HELLO THERE</h1>
<div class="carousel-caption">
<h4>High Quality Domain Names</h4>
<p>Domains that can help your business marketing</p>
</div> <!-- close carousel-caption -->
</div> <!-- close slide1 -->
</div>
This allows your height/width properties to be applied, and for the background image to display.
Along with crazymatt's suggestion to organize the nested elements a bit more, you can use the background-size and background-position rules to display the image as needed for each individual slide.
jsfiddle example
I have found the solution by ammending the media queries that the site was using. What I had to do was make sure that I had an explicit media query rule to cover all potential screen widths. In the media queries, I specified the background images for the carousel slides. By doing this, I found I always had the background images correctly populated. Previously, for a certain range of screen sizes, I was just letting default CSS define the background images, and this meant the background image for the first slide didn't show. I guess adding media queries for all possible screen sizes meant there was always a "trigger" to populate the background images.
Thanks also to those who offered a reply.
The main structure I'm using is:
<div class="portfolio-thumbs">
<div class="col-md-4 thumb-item">
<a href="#">
<div class="thumb-img">
<img src="./img/portfolio/rocksea.jpg" class="img-responsive" />
<div class="thumb-overlay"></div>
</div>
</a>
</div>
...
</div>
I've created a full JS Fiddle here
I'm looking to add a semi-transparent overlay to the image (will later be adding transition and some content to slide in from bottom of each image), yet can't seem to get it to appear.
Have compared to couple of other articles on SO but none seemed to fit the bill.
I've done this a thousand times before, any idea what's going wrong with this?
With help of #ZachSaucier , adding 100% height to all elements in tree. Also adding:
div.latest-work div.portfolio-thumbs div.thumb-item a div.thumb-img div.thumb-overlay {
position: absolute;
top: 0;
}
Made the overlay sit on top of the img.
Updated fiddle here
i am using the "old" FB Likebox:
<div class="container">
<div class="row-fluid">
<div class="span12">
<div id="fb-root"></div>
<script src="http://static.ak.connect.facebook.com/js/api_lib/v0.4/FeatureLoader.js.php" type="text/javascript"></script>
<script type="text/javascript">FB.init("394109690683544");</script>
<fb:fan height="120px;" width="100%" logobar="false" stream="false" connections="12" css="http://myurl.com/facebook.css" profile_id="562615520421911" class="fb_iframe_widget "></fb:fan>
</div>
</div>
</div>
how can i change the css to always have a 100% width? I need to use the box with twitter bootstrap and responisve.
thank you
It will not work, if you look at the code that's generated
<fb:fan height="120px;" width="200%" ...
translates into
<iframe id="f13ed26db2962a6" class="fb_ltr" scrolling="no" name="f2625075f1fd254" style="border: medium none; overflow: hidden; height: 120px; width: 200px;"
Which means that the widget reads only the values as the iframe is set to 200px not 200%
EDIT:
Seems like I was able to hack a bit with jQuery to make that happen, however becaue I can't set the span to 100% even when its display:block I'm using document width to set the span to the appropriate width, however you might need to change that to the width of the parent div. Again hacky but might get you started...
JSFiddle
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>
I have following webpage:
<div id = "wrapper">
<div id="leftmenu>
...
</div>
<div id="search">
...
</div>
<div class="Container">
<div id="content">
<iframe id="iF" name="if" src=""></iframe>
</div>
</div>
</div>
It bascially shows the menu in the left search bar on top and iframe with content below search bar and next to the menus. Problem i am having is i dont want it to show vertical and horizontal scrollbars inside ifram but rather use browsers scrollbars.
if i set like this in css:
.Container
{
position:absolute;
width:100%;
height:100%;
left:180px;
}
It removes horizontal scrollbar but is not removing vertical scrollbar. Can anyone guide me how to remove this vertical scrollbar from iframe.
Try: overflow: hidden; on your iframe.
#content iframe {
overflow: hidden;
}
Try this... After the iframe loads it resizes it using javascript. It'll only work if the iframe src is of the same domain.
<div id = "wrapper">
<div id="leftmenu>
</div>
<div id="search" >
</div>
<div class="Container">
<div id="content">
<iframe id="iF" onload="resize(this)" name="if" src="/"></iframe>
</div>
</div>
</div>
<script>
function resize(elem){
var outer=elem;
var inner=elem.contentDocument.documentElement;
outer.style.border="0";
outer.style.overflow="hidden";
outer.style.height=Number(inner.scrollHeight+10)+"px";
outer.style.width=Number(inner.scrollWidth+10)+"px";
}
</script>
There should be a scrolling attribute for the iframe you can just set to no, that takes care of the scrolling.
The iframe doesn't know it needs to be larger than the page it is in. If you know the height of the page you are attempting to show in the iframe, you can set the iframe height accordingly.
That being said, if the page you are displaying may change in size, your maintenance makes this pointless.
Charlie Frank's answer is good for same domain applications.
