Twitter Bootstrap 3 breakpoints based on actual width of container - css

I am using Bootstrap 3 (and Angular) for a webapp. I have sidebars which can be toggled, they are not using bootstrap (but table-cell layout)
I created a demo here: http://plnkr.co/edit/0pGjRqfqF21lGvhuNb9k?p=preview
Is it possible to make bootstrap columns break relative to the actual with of the container they are in?
Example:
A col-sm-* should break if its container (aside-main) is <768px, not the screen ?
<div class="row" ng-controller="demoCtrl">
<div class="aside-container">
<div class="aside-main">
<div class="col-sm-12">
<h2>Main Content Area</h2>
<div class="row">
<div class="col-sm-6">
<strong>column 1</strong>
</div>
<div class="col-sm-6">
<strong>column 2</strong>
</div>
</div>
</div>
</div>
<div class="aside" ng-if="asideIn">
<div class="col-sm-12">
<h2>Aside Area</h2>
here is the aside content
</div>
</div>
</div>

In 2018 seems there are such possibilities.
According to the documentation of project https://github.com/marcj/css-element-queries all you have to do is following.
Let's say you have following html element.
<div class="parent">
<h2>Test</h2>
</div>
And you define following css
.parent h2 {
font-size: 12px;
}
.parent[min-width~="400px"] h2 {
font-size: 18px;
}
.parent[min-width~="600px"] h2 {
padding: 55px;
text-align: center;
font-size: 24px;
}
.parent[min-width~="700px"] h2 {
font-size: 34px;
color: red;
}
And include scripts
<script src="src/ResizeSensor.js"></script>
<script src="src/ElementQueries.js"></script>
Functionality of the project will find html elements that css is referring to and will only listen to changes of those elements.
"no performance issues since it listens only on size changes of
elements that have element query rules defined through css. "
e.g. when an element that is "watched" exceeds width of 400 on watched element will be added css attribute min-width 400px and defined css will be applied to it.
Also for this to work you need to trigger the event listening or initialization yourself:
var ElementQueries = require('css-element-queries/src/ElementQueries');
//attaches to DOMLoadContent
ElementQueries.listen();
//or if you want to trigger it yourself.
// Parse all available CSS and attach ResizeSensor to those elements which have rules attached
// (make sure this is called after 'load' event, because CSS files are not ready when domReady is fired.
ElementQueries.init();
It's not exactly breaking bootstrap columns, but you can control css based on the width of the container. Should suffice.

Refactoring CSS to reduce adjoining classes

Is there a way of writing CSS to reduce the file size of a style sheet containing lots of adjoining classes. Example...
body .elementor-2 .elementor-element.elementor-element-949d9dd .elementor-widget-spacer,
body .elementor-2 .elementor-element.elementor-element-427933f .elementor-widget-spacer,
body .elementor-2 .elementor-element.elementor-element-cb8ce37 .elementor-widget-spacer {
margin-bottom: 0px;
}
hey Use :is selector to reduce the code please check. to learn more about it here
body .elementor-2 .elementor-element:is(.elementor-element-949d9dd, .elementor-element-427933f, .elementor-element-cb8ce37 ) .elementor-widget-spacer {
margin-bottom: 10px;
background: red
}
<div class="elementor-2">
<div class="elementor-element elementor-element-949d9dd ">
<div class="elementor-widget-spacer">spacer</div>
</div>
</div>
<div class="elementor-2">
<div class="elementor-element elementor-element-427933f">
<div class="elementor-widget-spacer">spacer</div>
</div>
</div>
<div class="elementor-2">
<div class="elementor-element elementor-element-cb8ce37 ">
<div class="elementor-widget-spacer">spacer</div>
</div>
</div>
If you use the widget spacer in a different position every single widget makes those classes with the different ids. So you can't reduce the classes.
So if you need not write all the classes on the CSS file.
Use this CSS.
body .elementor-widget-spacer {
margin: 0 !important;
}
or
body .elementor-widget-spacer {
margin: 0;
}
It works with all of the spacer widgets on the webpage.
if you are using elementor.you don't need to do it with custom CSS. Elementor has a dedicated control for this. edit the column, select the layout tab to find widget space, and make it 0. Inside the column, your widget gap will be 0.
Before Doing 0
After Doing 0
Or
you are not using Elementor you can go with :is().To learn more about it follow the article Here

How to fit a image inside a p tag which is under another p tag

I am using quill editor. and storing the data inside MySQL DB along with the HTML tag.
Example:
<p>heading<p><p><img src=""></p>
Now as I am using angular I have used below code reproduce the same HTML structure which I have saved earlier in DB.
<div class="container-fluid">
<h3 class="fancyFont">Hot Posts</h3>
<div class="row justify-content-md-center">
<div class="col-md" style="width: 100%">
<div style="background:lightgray;">
<div *ngFor="let post of allPosts">
<p [innerHTML]=post.postContent></p>
</div>
</div>
</div>
</div>
</div>
and to give it a proper style I have used the CSS below
p img{
max-width: 100% !important;
}
p {
margin: auto;
padding: 16px;
max-width:100%;
display: inline block;
word-break: break-all
}
But despite doing this I cannot resize or fit my image inside the p tag. To describe innerHtml I can say it will look like this in plain HTML
if you have 2 posts in allposts
[![<div>
<p><p><h1>first post</h1></p></p>
<p><p><h1>Second post</h1><p><p>image</p><p>
<div>][1]][1]
Maybe p inside p tag invalid for HTML 5 and I agree with that. As few members already gave me proof and I also checked it by myself. But in the case of Angular when you use innerHTML like
<p [innerHTML]=post.postContent></p>
It doesn't even matter (Yes I checked my web dev tools and it is working perfectly fine). So the question arises why I was not able to add style to my image tag by using
p img{
max-width:100% !important;
}
p {
max-width:100%;
word-break: break-all
}
because for innerHTML content angular doesn't support that until and unless you add below code in your component.ts file

Bootstrap 3 - Remove guttering

Is it possible to remove the padding from one particular grid within Boostrap 3 -
I need to layout images responsively but the design requires no gaps between columns.
Bootstrap 3 introduced row-no-gutters in v3.4.0
https://getbootstrap.com/docs/3.4/css/#grid-remove-gutters
Yep you can do it by creating a custom style sheet and adding a additional css selector to the col class. [http://www.bootply.com/FtnGzu0dea][1]
/* CSS used here will be applied after bootstrap.css */
.thumbnails {
padding: 0;
}
<div class="wrapper">
<div class="container">
<div class="col-md-3 thumbnails">
<div class="thumbnail"><img src="http://placehold.it/350x150"></div>
</div>
<div class="col-md-3 thumbnails">
<div class="thumbnail"><img src="http://placehold.it/350x150"></div>
</div>
<div class="col-md-3 thumbnails">
<div class="thumbnail"><img src="http://placehold.it/350x150"></div>
</div>
<div class="col-md-3 thumbnails">
<div class="thumbnail"><img src="http://placehold.it/350x150"></div>
</div>
</div>
</div>

My suggestion is to add a class for removing the padding at a certain media query width. Here is a test case that uses a header image that should respect the padding at all but the small size. At that point it has no padding and fits the full width of the viewport. I highly recommend using #screen-xs-max if you are compiling LESS source files. It avoids the one pixel jump for media queries that use max-width.
http://jsfiddle.net/jmarikle/htmn5Lov/
CSS
#media (max-width: 767px) { /* replaced with #screen-xs-max if using LESS */
.sm-no-padding [class*=col-] {
padding: 0;
}
}
HTML
<div class="row sm-no-padding">
<div class="col-sm-12">
<img class="img-responsive" src="//placehold.it/2000x1000"/>
Image and/or content in a row where we remove the padding for small screens
</div>
</div>
If you want more granular control with columns rather than at the row level, just apply the class to the columns and change your selector to [class*=col-].sm-no-padding
You can also create a new CSS class and add the following code into your stylesheet.
Custom CSS:
.no-padding > [class*='col-'] {
padding-right:0;
padding-left:0;
}
new CSS to use into your HTML div
.no-padding

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>

zurb foundation is it possible to have full row width

I'm using foundation 3 to build a responsive website but I want to have the Footer and Navigation background width to occupy the entire width? I have named my rows as
class="row navigation"
class="row footer"
I tried looking for how to fix this but I'm out of options. I'm assuming it is a small fix in the foundation.css file but it's a bit too overwhelming at the moment as I'm new to it.
Any poiinters much appreciated.
I ran into the same problem yesterday. The trick is, for full width spanning blocks, you just keep them out of the row/column structure, since row/column will always apply the default padding. Keep your footers and headers on their own, and use row/column inside them.
<header>
This will span the full width of the page
</header>
<div class="row">
<div class="twelve columns">
This text will flow within all typical padding and margins
</div>
</div>
<footer>
This will span the full width of the page
<div class="row">
<div class="twelve columns">
This text will flow within all typical padding and margins
</div>
</div>
</footer>
What I have been doing is to add a custom class so that I can chain it with .row and override the max-width setting.
<div class="row full-width"></div>
.row.full-width {
width: 100%;
max-width: 100%;
}
I put width in here too to cover bases, but it is already declared in foundation.css so you can just omit it.
If you're using Zurb Foundation Framework, simply remove the row class and wrap the element in a class container that is 100% width. Now you probably want to center the stuff, use class centered like this:
<div class="container navigation">
<div class="centered">
Some navigation stuff
</div>
</div>
I completely disagree with the answer. You shouldn't have to use !important
Please refer to my article and demo at http://edcharbeneau.github.com/FoundationSinglePageRWD/
You should be able to get what you need from there. The demo is for 2.2 but is very similar in function to v3.
Foundation 6 supports this feature naturally with row expanded. code example:
<div class="expanded row">
...
</div>
Read more here: http://foundation.zurb.com/sites/docs/grid.html#fluid-row
Use "Section" as in:
<section>
<div class="row">
<div class="small-12 columns">
</div>
</div>
</section>
Then, assign an ID to the section and use that for your background.
This is in regards to Foundation 5. None of the answers given so far, provide edge-to-edge, full widths. That's because inner .columns add padding.
For a true edge-to-edge, full width content, add this to your CSS.
.row.full { width: 100%; max-width: 100%; }
.row.full>.column:first-child,
.row.full>.columns:first-child { padding-left: 0; }
.row.full>.column:last-child,
.row.full>.columns:last-child { padding-right: 0; }
Simply add .full class to a .row you wish to extend full width.
<div class="row full">
<div class="medium-6 column">This column touches Left edge.</div>
<div class="medium-6 column">This column touches Right edge.</div>
</div>
Just override the max-width property as max-width: initial;, for example,
.fullWidth {
width: 100%;
margin-left: auto;
margin-right: auto;
max-width: initial;
}
<div class="row fullWidth"> </div>
this works for me :)
I know that there are already many answers, but I think I have something new to add in this topic if someone is using Foundation 5 and stumbled upon this question (like me).
As Foundation is using REM units, it would be best to alter .row class using them and by adding extra class, so you can have only selected rows full-width. For example by using .full class:
.row.full {
max-width: 80rem; /* about 90rem should give you almost full screen width */
}
You can see that it is used like this even in documentation page of Zurb Foundation (they altered .row class, though): http://foundation.zurb.com/docs/ (just look into page source code)
You really would want to keep the row class otherwise you lose a lot of the power of the grid system. Why not change the setting for $rowWidth from 1000 (default) to 100%. This can be found in the file foundation_and_overrides.scss
Just set the
$row-width: 100%;
http://foundation.zurb.com/forum/posts/927-full-width-layouts
I am not sure if I am missing something, but I had to add a .row div for the .centered to work. I can still style the .header to have a full width background in this case, but the .container method did not work for me.
<header class="header">
<div class="row">
<div class="centered">
Logo and stuff
</div>
</div>
<div class="row">
Some navigation stuff
</div>
</header>
If you don't give it the "row" class and put columns inside it works on a 100% width
If you're using sass, this is a better way:
<div class="row full-width"></div>
.row{
&.full-width{
width: 100%;
max-width: 100%!important; //might be needded depending on your settings
&>.column:first-child,
&>.columns:first-child{
padding-left: 0;
}
&>.column:last-child,
&>.columns:last-child{
padding-right: 0;
}
}
}
yes, just use like this:
<div class="large-12 columns">
<h2>Header Twelve Columns (this will have full width of the BROWSER <---->></h2>
</div>
