I have been using twitter bootstrap to design my homepage and something keeps bugging my mind about the usage of media queries in css frameworks such as twitter bootstrap.In my example i am displaying four images like
<div class="container">
<div class="row">
<section>
<article class="span3">
<img src="gandalf1.jpg" />
</article>
<article class="span3">
<img src="gandalf2.jpg" />
</article>
<article class="span3">
<img src="gandalf3.jpg" />
</article>
<article class="span3 last">
<img src="gandalf4.jpg" />
</article>
</section>
</div>
</div>
With the row class and basic resets for section,this works surprisingly well and it responds well down to mobile.I feel that i have no say on what's happening and so i want to get some control.
What i want is to force everything under the <section></section> into some kind of contract to make them behave in some way,for instance,in my example at some point,the images are listed one after another vertically.
In my contract for instance,i want the images to never leave their original order - (the original order is horizontal i.e one row with four images,the second row with four images and so forth) and should respond to the change of width by resizing without breaking out of their confines when the width is between 600px and 980px
#media screen and (min-width:600px) and (max-width:980px) { ... }
To achieve this,i have tried many things and the first thing i thought of is to make the <section> and inline-block,but that failed to produce the desired effect.I am afraid trying to redo the .row class will be a very tall order at those widths.
Should i concentrate my efforts on looking for a solution using my css code i write or should i try and modify the .row class at those widths?.

I have a very wide element, #widelement inside a bootstrap row col. I would like to enclose it on a div, .mywrapper, with a horizontal scroll bar in order to keep page layout.
Someone can explain to me what style I should add to .mywrapper to avoid that #widelement overflows the bootstrap col?
In this sample, the wide element has a 5000px width, but, this is not a fixed number, can be bigger or smaller, also smaller than col size.

What I tried unsuccessfully:
.mywrapper {
overflow-x: scroll;

Testing your solution I ended up with this snippet:
.mywrapper {

It turns out that the very code you have suggested works. So, something prevents it from working at your end, which could be one or more of the following:
client-side cache (your browser temporarily stores your css and js files in order not to have to download them each time you load a page and it's possible that when you have tested, the cached old version of your CSS was loaded by a locally cached file by your browser instead of downloading it from the server), Ctrl+F5 (or even clear browser cache or even testing in a freshly opened incognito window) sorts this out
server-side cache (CloudFlare or some other server-side software generates static files periodically and sends those out to the browser upon page load rather than generating the response upon each request), in which case, you need to clear the server-side cache while you are testing
you forgot to save the code when you have edited it
you forgot to deploy it on the server
the wrong file was edited
the right file was edited, but it was wrongly not included into the HTML
some higher prio CSS rule prevented the overflow-x rule from being applied (see https://developer.mozilla.org/en-US/docs/Web/CSS/Specificity)
So, your idea was correct, but something prevented it from providing the benefits you have expected. The issue therefore is something technical at your project and you will need to troubleshoot the potential issues listed above. If it still does not work at your end, then you will need to edit your question with more information and let the answerer(s), including myself know about the additional information.
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.
I have div in container that I want to be col--8 with offset-2 on medium, large, and extra large screens - this would put it in center of page and smaller with wide, however at same time when screen is small or extra small I want to offset to be removed and col--12 div being of full with
I tried with:
<div class="col-xs-12 col-xs-offset-0 col-md-8 col-md-offset-2" >
Some content here...
</div>
What I doing wrong ?
Ps. I also using angular on page...
Remove col-xs-offset-0. it is not necessary.
here is a forked jsFiddle
The classes that you have there should do the job so long as you have properly wrapped the div in parent .container and .row div elements. Including those wrappers would look like the following:
<div class="container">
<div class="row">
<div class="col-xs-12 col-md-8 col-md-offset-2" >
Some content here...
</div>
</div>
</div>
In Bootstrap 4 the syntax is a little bit change
col-lg-10 offset-lg-2
I've boiled my layout down to this fiddle or the full screen version
I am having two problems. The first, is that space between the side bar and the content is very large. I want them to be spaced as normal. In my case, I'm expecting the side bar to be span2 in size, my main content to be span7 in size and then a right hand column to be span3.
<div class="row-fluid">
<div class="span2">
<div class="well sidebar-nav-fixed">
<ul class="nav nav-list">
<li class="nav-header">Sidebar</li>
...other links ...
</ul>
</div>
</div>
<div class="span7 span-fixed-sidebar">
<div id="world-map" style="display:block;"> </div>
</div>
<div class="span3">
<div class="row-fluid">
<div class="span12" id="country-info">
<h2 id="country-info-header">
The Detail Header
</h2>
<p id="country-info-summary">
A set of summary information. A short paragraph of text.
</p>
</div>
</div>
</div>
However, I'm getting a result with a huge gap between my sidebar and my content (the red box), and the right hand content is on the left hand side and under my sidebar. How can I fix this layout?
You need to experiment with Bootstraps offset classes. I made you a quick example here:
http://jsfiddle.net/tXzjX/5/
Your position:fixed takes the element out of the natural flow of the page, and in a way "resets" the columns on the grid. Using Bootstrap's offset classes can counteract that issue. Check here: http://getbootstrap.com/2.3.2/scaffolding.html#gridSystem under "Offsetting Columns".
Could you not just reduce the margin size like so:
.row-fluid > .span-fixed-sidebar {
margin-left: 100px;
}
as that seems to move the red bar in nicely
EDIT: I have had a play about and come up with a slightly simpler looking code with what I think is the effect you require with a bit of tweaking. http://jsfiddle.net/bmgh1985/UeFRa/
Quick question involving foundation. If I want divs to go in order 1 then 2 on desktop and 2 then 1 on mobile, how would I accomplish this using Zurb?
<div class="row">
<div class="three columns">
</div>
<div class="nine columns">
</div>
</div>
Thanks so much for the help!
This can definitely be done. In your code you should order the div's based on how you would display it on the mobile, i.e. 2 then 1. For displaying it properly on larger screens you can override the default styling of the div's.
For testing purposes you can try:
<div class="row">
<div class="nine columns" style="float:right;">
</div>
<div class="three columns" style="float:left;">
</div>
</div>
While the above solution will work, I suggest not using inline styling. I would rather override using custom classes and/or #media tags.
Using those the code would be:
For the HTML:
<div class="row">
<div class="nine columns pull-right">
</div>
<div class="three columns pull-left">
</div>
</div>
For the CSS/Stylesheet:
#media only screen and (min-width: 768px) {
.pull-left {float: left !important;}
.pull-right {float: right !important;}
}
Not sure you can do this strictly with css, but with javascript you can add the pull-x classes when applicable.
theory:
Place the columns in the order you want for the mobile device, or small screens rather. Then in document.ready, check whether show-for-small is visibile or not, if not, you are on a larger screen and can apply push|pull classes to your columns of choice.
pseudo code, assuming you know push/pull technique:
// do this if not on small screen
if ( $('.show-on-small').css('display') == 'none' ) {
// pull or push the columns as needed
$('.myColumnsToPull-two').addClass('pull-two');
} else {
// might be a good idea to revert above change
}
