My markup:
<div class="container">
<div class="row">
<div class="col-xs-12"></div>
<div class="col-md-8 col-md-offset-2 col-sm-10 col-sm-offset-1 col-xs-12">
<div class="row"> <!-- this has 0 height -->
<div class="col-xs-6"></div>
<div class="col-xs-6"></div>
</div>
</div>
<div class="col-xs-12"></div>
</div>
</div>
What can be the reason that the nested row has correct width, 0 height and can't have a margin-bottom, no matter what contain its colums?
Interesting thing, when I positioned absolutely a pseudoelement ::after for this row, it resolves correctly sizes like top: 50% but only if the problematic row has position: static and not when it has position: relative.
The row's height might be collapsing due to its floated children? Try adding a clearfix to clear the row of its children's floats:
<div class="row clearfix">
I'm not entirely sure without seeing any of your own CSS that could be also causing issues, but the above might resolve the issue. FYI - The clearfix class ships with BootStrap.
Here's a good read and other information on clearfix: What is a clearfix?
I reproduced the problem: http://jsfiddle.net/phn3Lae6/1
When you remove position: absolute from ::after pseudoelement, row behaves normally.
Since ::before and ::after pseudoelements are an important part of Bootstrap grid, probably the best solution here is to not mess around with them, but to create a separate element inside the grid element to be a pseudoelement parent, for example like:
<div class="row">
<div class="pseudoelement-parent">
<div class="col-xs-6"></div>
<div class="col-xs-6"></div>
</div>
</div>
.pseudoelement-parent {
position: relative;
}
I'm trying to copy bootstrap's columns and I was also wondering why my row's height is 0. It turned out that display: table;, content: " "; and clear: both; are all important for the row's height.
I hope this helps someone.

I'm new to bootstrap 4 and am using the class "row" in multiple places. I want to add a margin-left to just one of these div tags with the class row, so I added an id to the div tag.
<div id="menumargin" class="row">
when I use this CSS
.row{
margin-left: -15px !important;
}
it works but affects all instances of row obviously.
However this CSS I write to just target this instance:
#menumargin.row{
margin-left: -15px !important;
}
doesn't work. It's as if the code isn't written at all.
Please advise.
I hope this question makes sense. I'm also new to Stack Overflow.
Columns have horizontal padding to create the gutters between individual columns, however, you can remove the margin from rows and padding from columns with .no-gutters on the .row.
The gutters between columns in our predefined grid classes can be removed with .no-gutters. This removes the negative margins from .row and the horizontal padding from all immediate children columns.
<div class="container">
<div class="row no-gutters">
<div class="col">col</div>
<div class="col">col</div>
<div class="col">col</div>
<div class="col">col</div>
</div>
<div class="row">
<div class="col-8">col-8</div>
<div class="col-4">col-4</div>
</div>

I have an article about bootstrap here How to Responsive Design with Bootstrap?
I have place two div inside an inline-flex div one of the two divs width reduces. I'm using bootstrap:
<section>
<div class="container">
<div class="flexx">
<div class="foo">
....
</div>
<div class="col-md-10">
<div class="card">
<div class="card-block">
...
</div>
</div>
</div>
</div>
</div>
</section>
Basically, foo class should be inline with col-md-10 which it does but col-md-10 gets small instead it should still be at 100%. Am I doing it correct? I'm not strong with css/scss.
I'm not sure I entirely understand your issue. inline-flex items do not default to full width. You will need to add some css for that to happen since in the css for bootstrap the flex-grow property is set to 0;
I think adding one style and a class will fix your issue, again if I understand you right.
// to your html
<div class="col foo">
....
</div>
// to your css
[class^="col"] {
flex-grow: 1;
}

I'll start off by stating that I know this question has been asked a lot, but none of the answers I saw seemed to work for me.
Basically, I have some divs inside of a larger div. They'll have dynamic text, so I don't know how many lines each will be. The problem is that I can't seem to get the divs to size themselves to the parent's height. I want the column divs to take up the entire height of the row div (basically, I want that blue part to fill all the space between the bars).
HTML:
<div class="container">
<div class="row divOne">
<div class="col-xs-3 divTwo">Some Text</div>
<div class="col-xs-3">
Some text that could wrap to multiple lines
</div>
</div>
<div class="row divOne">
<div class="col-xs-3 divTwo">Different Text</div>
<div class="col-xs-3 divThree">
With some more text
</div>
</div>
</div>
CSS:
.divOne
{
border-top:10px solid black;
}
.divTwo
{
background-color: #32649b;
height:100%;
color:white;
}
jsfiddle:
Now, what I've learned from other versions of this question are that
float:left might be screwing it up
height:100% doesn't work if the parent's height is defined
position:relative might help on the parent
The problem with the float is that I'm using bootstrap, and that's where the float is coming from, so I don't really want to mess with that.
I can't really define parent height, because it'll be dynamic based on the children.
I also tried messing around with position:relative on the parent and absolute on the child, but that seemed to get really screwy. I'm also guessing this won't work because I'm using bootstrap. It's possible that I'm just missing something, though. I'll admit to not being the greatest with CSS.
I don't know if I'm having these issues because I'm using bootstrap, or because I'm just being an idiot right now.
Something else that seems to be throwing a wrench into things: These columns will be laid out differently on smaller screens vs. larger ones. I actually want something along the lines of col-xs-12 col-md-3 for these.
The short answer is that you can't really achieve this within the constraints of the bootstrap framework. There are plenty of articles that explain why div elements can't stretch to the height of their container, and how to get around this problem. One of the solutions I'm most fond of is Faux Columns.
But, let's get a little more creative then that.
I came up with something that might work for your scenario, but requires a bit of change to your markup. Here's a solution that wraps the bootstrap grid with display: table.
http://jsfiddle.net/Wexcode/13Lfqmjo/
HTML:
<div class="table-container">
<div class="table-row divOne">
<div class="col-xs-3 divTwo">Some Text</div>
<div class="col-xs-3">
Some text that could wrap to multiple lines
</div>
<div class="col-xs-6"></div>
</div>
</div>
CSS:
.table-container {
margin: 0 -15px;
}
.table-row {
display: table;
width: 100%;
}
.table-row [class^="col"] {
display: table-cell;
padding: 0 15px;
float: none;
}
Note that for this solution to work, you must include enough col elements to stretch it all 12 columns (see that I added an empty .col-xs-6 div).
You can add
display:flex;
to divOne , and will act like you wanted.
in bootstrap 4 'row' class applies this on div, but in ealier versions you need to add manually if you expect such behavior.
Give .divOne a display: flex and remove the height: 100% from .divTwo:
.divOne
{
border-top:10px solid black;
display: flex;
}
.divTwo
{
background-color: #32649b;
/*height:100%;*/
color:white;
}
<link href="https://maxcdn.bootstrapcdn.com/bootstrap/3.2.0/css/bootstrap.min.css" rel="stylesheet"/>
<div class="container">
<div class="row divOne">
<div class="col-xs-3 divTwo">Some Text</div>
<div class="col-xs-3">
Some text that could wrap to multiple lines
</div>
</div>
<div class="row divOne">
<div class="col-xs-3 divTwo">Different Text</div>
<div class="col-xs-3 divThree">
With some more text
</div>
</div>

I have the following div:
<div style="background:red;width:100%;height:100%">Red</div>
When I stick it into the page without a container div, I can see it. But when I stick it into a container
<div class="container">
<div style="background:red;width:100%;height:100%">Red</div>
</div>
I can't see that div at all. When I stick it into an additional:
<div class="row">
<div class="span3">
<div style="background:red;width:100%;height:100%">Red</div>
</div>
</div>
I can see it, but there is a lot of padding and tons of spacing all around. How can I create a container div that doesnt have any margins/padding etc. that is equal to 0?
In fact, if you are using Bootstrap grid system, some margins and padding are added to maintain spacing between columns and page boundaries. So direct answer to your question is: no, you can't.
However, you can simply have a div that is not wrapped in div with .container class - then your div will not have any margins and paddings derived from grid system.
<div class="container">
<div class="row">
<div class="col-md-8">8-units column</div>
</div>
</div>
<div style="width: 100%; background: red;">Your div to be expanded to full page's width</div>
<div class="container">
<div class="row">
Another div within grid system
</div>
</div>
I am trying to create a 4 column <div> layout.
Why are the row containers not drawing a border around the respective row?
Also, is this a good approach, as in is my css written well to be fluid and for dynamic resizing of the browser window?
Any suggestions or help would be most appreciated.
Here is my current attempt.
You need to set the overflow to auto when using float. http://jsfiddle.net/gJJHs/
The problem seems to be that you are floating your columns, and when you float things, they take up effectively zero space.
I think the solution is to cancel the float in you "last" class and add a "dummy column" to each row.
This CSS seems to work:
.col
{
float: left;
width: 25%;
}
.last{
clear: left;
}
.row{
border: 1px solid green;
}
Revised HTML (with dummy last column):
<div class="row">
<div class="col">1</div>
<div class="col">2</div>
<div class="col">3</div>
<div class="col">4</div>
<div class="last" />
</div>
<div class="row">
<div class="col">5</div>
<div class="col">6</div>
<div class="col">7</div>
<div class="col">8</div>
<div class="last" />
</div>
When an element is floated, its parent no longer contains it because the float is removed from the flow. The floated element is out of the natural flow, so all block elements will render as if the floated element is not even there, so a parent container will not fully expand to hold the floated child element.
As such, the border will seem like it is not bordering anything :( Take a look at the following article to get a better idea of how the CSS Float property works:
The Mystery Of The CSS Float Property
As others have said, if you add overflow: auto; to your .row class, it'll take care of the problem. Here's another article that explains why to use overflow.
http://www.quirksmode.org/css/clearing.html
I hope this helps.

it's the float left. That takes the divs "out of flow" and it's drawing the border around empty space essentially
Yet another option, in addition to the other answers, is to add overflow: hidden; to your .row.
The reason for the behavior you saw is that float takes the div outside of the normal flow. The div then essentially takes up no space in the document.
This makes sense if you think about the ostensible purpose of floating an image in order to wrap text around it. The next p tag (for example) is positioned as if the floated image wasn't there, i.e. overlapping the image. Then, the browser wraps the text within the 'p' tag around the image. (If the floated image was not "removed from the flow", the p tag would naturally appear below the image—not giving the desired effect.)
Here's how I'd write the code.
HTML:
<div class="row">
<div class="col">1</div>
<div class="col">2</div>
<div class="col">3</div>
<div class="col">4</div>
</div>
<div class="row">
<div class="col">5</div>
<div class="col">6</div>
<div class="col">7</div>
<div class="last">8</div>
</div>
CSS:
.col
{
float: left;
width: 25%;
}
.row{
border: 1px solid green;
overflow: hidden; /* "overflow: auto;" works just as well instead */
width:100%; /* Helps older versions of IE */
}
Add a "float:none;clear:both" to your .row and you'll see the rows appropriately. But for the fluid behavior and design that you are looking for, you'll want to apply some javascript (like jQuery Equal Height: http://www.jainaewen.com/files/javascript/jquery/equal-height-columns/) to be consistent across browsers without a ton of CSS hacking.
