I'm learning Bootstrap and I want to create simple div which is centered on the page.
I really like that auto-margin of container class, but it seems to be jump-changing based on breakpoints when resizing window width.
I want to make margins getting smaller smoothly until they become 0 when window is small enough.
I have tried to explicitly set one column layout like this:
<div class="container border">
<div class="row">
<div class="col-12">
<p>container with some content</p>
</div>
</div>
</div>
but the results are just the same and breakpoints all still used.
For that you shouldn't use bootstrap containers, because they have fixed width on breakpoints. For smooth transition you should manually set width to you container in % or vw and margin in same units.
There are two types of Bootstrap 4 Container: Fixed and Fluid.
Choose from a responsive, fixed-width container (meaning its max-width changes at each breakpoint) or fluid-width (meaning it’s 100% wide all the time).
If you don't want the breakpoints, use the container-fluid class:
Use .container-fluid for a full width container, spanning the entire width of the viewport.
<link href="https://stackpath.bootstrapcdn.com/bootstrap/4.3.1/css/bootstrap.min.css" rel="stylesheet"/>
<div class="container-fluid border">
<div class="row">
<div class="col-12">
<p>container with some content</p>
</div>
</div>
</div>
If you must, you can manually override Bootstrap's responsive max-width settings.
.container.nobreakpoints {
max-width:100%;
width:800px; /* maximum width before margins appear */
}
<link href="https://stackpath.bootstrapcdn.com/bootstrap/4.3.1/css/bootstrap.min.css" rel="stylesheet"/>
<div class="container border nobreakpoints">
<div class="row">
<div class="col-12">
<p>container with some content</p>
</div>
</div>
</div>

I would like to have 2 columns, with the left column being a video (with aspect ratio 16x9) and the right column being a sidebar (with min-width). When the width of the window changes, the video should resize accordingly and the sidebar should maintain it's width.
However, I can't understand why there is a padding top for .ratio::before.

Here is my code:
<div class="container" id="main">
<div class="d-flex" id="row-main">
<div class="col-sm-9 col-12">
<div class="flex-grow-1" id="content">
<div class="ratio ratio-16x9">
<video id="vid"></video>
</div>
</div>
</div>
<div class="col-sm-3 col-12" id="sidebar">
<iframe class="chat"></iframe>
</div>
You should put the ratio class on the element you want to have the 16x9 aspect ratio. This just leaves the ratio-16x9 class on the parent div, and the ratio itself on the video.

I'm looking for a way to maximize a map inside a Bootstrap row. In the following syntax, the left col-md-9 div is the map, and the right side is a fixed 240px wide image.
<div class="row">
<div class="col-md-9">
<div id="mapid" style="width: 100%; height: 400px;"></div>
</div>
<div class="col-md-3">
<p id="delta">
<%= #myimage %>
<br>
</p>
</div>
</div>
With a fluid layout, it can get ugly quickly. Is there a way to maximize the map in a fluid layout? I want the map to increase with the fluidity and the image retaining 240px with a small margin.
You can just do it with flexbox, and there are utilities from Bootstrap you can use: https://getbootstrap.com/docs/4.3/utilities/flex/
<div class="d-md-flex flex-md-row flex-md-nowrap align-items-md-start">
<!-- map -->
<iframe />
<!-- image -->
<img />
</div>
Since the map/iframe is setup as 100% width, normally this will push the other item off the row. But with flexbox, by default, the flexbox children have flex-shrink: 1; turn on. That means it will shrink for you. That's how you can get the width maximization for the map.

I have bootstrap container (div class="container") and there are two rows (div class="row").
But between those rows I need one full width horizontal line. Full width - I mean that it should be full width - outside container. This line is just for design issues, it would have background color and that is it. I do not know how to create it.
Divide your content into 2:
<div class="container">
<div class="row">
stuff here
</div>
</div>
<div class="line"></div>
<div class="container">
<div class="row">
stuff here
</div>
</div>
I know there is a few ways to do this, but I want to put this out there to see if there are any clean / good examples of ways to do this as I haven't had any luck searching.
So in Bootstrap, I basically have an aside that goes full width under 780px. Just thinking about that aside, it is a unique situation where that section actually gets larger as the viewport gets smaller.
Let me try to clarify... say the entire page width is 1200px and I am using a container -> row -> col-md-9 & a col-md-3. The col-md-3 is the aside. Inside the col-md-3 is a form with a nested grid of 2x col-sm-6 divs. So as the page drops through the break points, when it gets under 980px, the aside becomes full width and thus wider than it was at 1200px.
Bootstrap is setup so if you use col-sm-6 that column goes from 50% width to 100% width under 780px. I need to figure out how to do the opposite of that.
I need col-sm-6 (or however I need to custom tag, etc.) to go from 100% length to 50% length under 780px.
How can I do this? Thanks in advance!

So in the example above... Box 1 and Box 2 stay next to each other until the viewport width is below 768px.
What would be the best way to write this so Box 1 and Box 2 were stacked until the viewport went below 768px wide... then they go on the same line / inline / whatever?
You can use multiple col-*-* classes on any columns within a bootstrap row. In your case, you would use col-xs-6 col-sm-12 to make any columns appear side-by-side on the smallest layout, but stacked on anything above:

And here is a Bootply demonstrating this behaviour.
I'm trying to set some divs to width: 100% on Twitter Bootstrap 3 (including no paddings or margins).
JSfiddle: http://jsfiddle.net/rq9ycjcx/
HTML:
<div class="container">
<header>
<div class="row">
<div class="col-md-2">
<img src="http://placehold.it/150x50">
</div>
<div class="col-md-10">Menu</div>
</div>
<div class="row gray">
<div class="col-md-6">
<h1>Page Title</h1>
</div>
<div class="col-md-6">
<div class="breadcrumbs">Main page > page </div>
</div>
</div>
<div class="row">
<div class="col-md-12">
<img src="http://placehold.it/350x150" />
</div>
</div>
</header>
<footer>
<div class="row">
<div class="col-md-12">Content</div>
</div>
<div class="row dark">
<div class="col-md-3">Footer 1</div>
<div class="col-md-3">Footer 2</div>
<div class="col-md-3">Footer 3</div>
<div class="col-md-3">Footer 4</div>
</div>
</footer>
</div>
What is the right way to get image http://placehold.it/350x150 width: 100%, including no paddings or margins?
Page title and breadcrumbs height is 80px.
If I resize window to smaller screen (e.g. mobile), text Main page > page disappears (it's somewhere but not on own row).
How to fix it?
Use <div class="container-fluid">. As per Bootstrap Docs: Use .container-fluid for a full width container, spanning the entire width of your viewport.
There is 0 padding on container-fluid.
In your code you have what appears to be body content in your header and you also have a div class="container" outside of your header and footer. This is not correct, you should have your container/container-fluid inside of your body. Also for your header you should use <nav="nav navbar-nav">.
Updated Fiddle
As suggested above, you can create a helper class
.padding-0 {
padding: 0;
}
and apply it to any HTML elements for which you need a padding reset. So in your case, it would look like this:
<div class="row">
<div class="col-md-12 padding-0">
<img src="http://placehold.it/350x150" />
</div>
</div>
For the second problem, set height of .gray class to auto :
#media () {
.gray {
height: auto;
}
}
Note: You could also remove line-height: 80px, it's optional :)

There is no "right" way to do that in Bootstrap 3. It means you have to reset padding for the exact column.
You can create a class such as this one:
.col-md-12.resetPadding { padding:0px }
About Main page > page disappearing, I don't see this problem on my browsers (tested on Chrome and FF), but you have line-height: 80px there and as you said your breadcrumbs div has height: 80px;, so try to reduce line-height property and see how it works.
A simple way would be to remove the <div class="col-md-12">...</div> and add your content directly inside the row tag. The row tag removes the left & right gutters, whereas the cold-md-12 essentially adds the gutters back in.
The Bootstrap 3 documentation says that for single full width items you don't need any markup, eg just wrap it in <p> tags. However this will show the 15px gutters due to the page markup. So by simply adding in the row tag and placing your content directly inside this you will get 100% width content and be compliant with the BS3 documentation.
