I'm with Bootstrap 4 alpha 3 and I need a simply vertical alignment of this code in page with this code:
<div class="container">
<div class="row">
<div class="col-sm-4" style="background-color:#ff0000;">Prova</div>
<div class="col-sm-4">
<h1 class="text-xs-center">HELLO!</h1>
</div>
<div class="col-sm-4"></div>
</div>
</div>
If you can opt to use v4's flexbox mode, the columns will have the same height automatically.
Then to vertically align the text, add display: flex and align-items: center to the desired column.

I can't understand why this doesn't work. There are 12 columns but it's work only with 11
HTML
<section>
<div class="container">
<div class="row">
<div class="advantages col-12">
<div class="col-4">one</div>
<div class="col-4">two</div>
<div class="col-4">three</div>
</div>
</div>
</div>
</section>
SASS
.advantages
text-align: center
div
display: inline-block
You should remove col-12 and let your col-4 sit within .row. A col must be immediately preceeded by a row.
Since 4+4+4 = 12, you don't have to define your previous col-12, and you shouldn't have to set anything to inline-block.
It's what #Jay Kariesch said, but you can also keep advantages in the same div as row, like this:
<div class="advantages row">
This way you will keep advantages class working for all the divs inside.
I want an element to be centered vertically in a page and i am using bootstrap 4.0. Most of the methods i found were about earlier versions or the alpha, and the official method doesn't work, so, could someone please explain clearly once and for all how to center an element vertically in bootstrap?
Use Bootstrap's align-items-center, which can be read here
<div class="container">
<div class="row align-items-center">
<div class="col">
One of three columns
</div>
<div class="col">
One of three columns
</div>
<div class="col">
One of three columns
</div>
</div>
</div>
EDIT
You can also use Bootstrap's new support for flex box to center vertically, which can be read here
<div class="d-flex align-items-center">...</div>

Center a column using Twitter Bootstrap 3

Closed 6 years ago.
I'm trying to get the content in <div class="col-md-2 col-lg-2"> in the middle to align to middle, but to no avail.
I know that setting the columns to a size of 2 will not fill the space of the grid system of 12 columns, but I want it to be aligned to the middle regardless.
<div class="row">
<div class="col-lg-12">
<h1 class="content-header">Header</h1>
<div class="row">
<div class="col-md-2 col-lg-2">
content
</div>
<div class="col-md-2 col-lg-2">
content
</div>
</div>
</div>
found a css trick that works
.row-centered {
text-align: center;
}
.col-centered {
display: inline-block;
float: none;
/* reset the text-align */
text-align: left;
/* inline-block space fix */
margin-right: -4px;
}
Bootstrap 4, like Bootstrap 3, uses offset to move or center entire columns. So in your case use offset-*-4 to move it over 4 cols in the 12 col grid.
<div class="row">
<div class="col-lg-12 text-xs-center">
<h1 class="content-header">Header</h1>
<div class="row">
<div class="col-md-2 col-lg-2 offset-md-4 offset-lg-4">
content
</div>
<div class="col-md-2 col-lg-2">
content
</div>
</div>
</div>
</div>
To center inline elements (like text), use:
text-center (this was text-center in 3.x)
To center block elements (like DIV) or columns, use:
mx-auto (this was center-block in 3.x)

There are also new responsive alignment classes in Bootstrap 4 so you can align differently at various breakpoints.
I have been looking over other questions posted on SO and tried the CSS however I cannot seem to align the "box" HxV within the container.
What is the best way to get it to display HxV responsive?
HTML:
<div class="container">
<div class="row">
<div class="col-md-8 col-md-offset-2 center-block">
box
</div>
</div>
</div>
Create an class like .centred-col and write an rule like
.centred-col{ float: none; margin:auto;}add this after ur .col classes.
Using .container centers and auto margins your grid to begin with, there should be no need for offsets:
<div class="container">
<div class="row">
<div class="col-xs-12">
box
</div>
</div>
</div>
Note: .col-xs-12 will set your column to the full width after container margins from the XS size to the LG size.

How to turn a bootstrap 3 col-lg-x into a "fixed height size" column with vertical scrolling bar? I did many research and tried several CSS codes but no way.
Update: I have this code, but it's scrolling horizontally:
.scrollablepage > :last-child
{
height:552px;
overflow-y:scroll;
}
Html:
<div class="container">
<div class="row">
<div class="col-lg-8 scrollablepage">
<div class="well well-sm">
<p>
hellohellohel lohellohellohellohell ohellohellohellohellohelloh ellohellohellohe
llohellohel lohelellohellohellohell ohellohellohel lohellohellohellohell
ohellohellohellohelloh ellohellohellohellohellohellohellohellohel
</p>
</div>
</div>
</div>
Why it's scrolling horizontally and not vertically?
