How can I horizontally center an element?
With flexbox
it is very easy to style the div horizontally and vertically centered.
#inner {
border: 0.05em solid black;
}
#outer {
border: 0.05em solid red;
width:100%;
display: flex;
justify-content: center;
}
<div id="outer">
<div id="inner">Foo foo</div>
</div>
How can I horizontally align my divs?
To achieve what you are trying to do:
Consider using display: inline-block
instead of float
.
Vertical and horizontal align (middle and center) with CSS
There are many methods :
- Center horizontal and vertical align of an element with fixed measure
CSS
<div style="width:200px;height:100px;position:absolute;left:50%;top:50%;
margin-left:-100px;margin-top:-50px;">
<!–content–>
</div>
2 . Center horizontally and vertically a single line of text
CSS
<div style="width:400px;height:200px;text-align:center;line-height:200px;">
<!–content–>
</div>
3 . Center horizontal and vertical align of an element with no specific measure
CSS
<div style="display:table;height:300px;text-align:center;">
<div style="display:table-cell;vertical-align:middle;">
<!–content–>
</div>
</div>
Align HTML elements horizontally in a div
Just add text-align: center
to your wrapper to set the horizontal alignment of all non-floating/non-positioned children:
div{
text-align:center;
}
<span>
are inline elements by default. Thus you either have to use display:block
on them and style them appropriately, or just tweak the parent style a little bit. Since there are no other children than the <span>
and the <button>
s your best of with this simple solution.
Note that text-align:<value>
gets inherited from the parent, so if you want to include something else in your wrapper you should check whether text-align:center
is okay for you. Otherwise use text-align:<value>
in the specific element, where value
is left
, right
, center
or justify
.
JSFiddle Demo
Vertical and Horizontal alignment of text with CSS
You can change just your CSS to this (no HTML changes):
div{
background: red;
bottom: 0;
height: 100px;
left: 0;
margin: auto;
position: absolute;
top: 0;
right: 0;
width: 100px;
text-align: center;
line-height: 100px;
}
The text-align
is self-explanatory. The line-height
forces the text to the center by matching the height of a single line to that of the div. You will have to adjust it to your needs each time.

How do you easily horizontally center a div using CSS?
In the case of a non-fixed width div (i.e. you don't know how much space the div will occupy).
#wrapper { background-color: green; /* for visualization purposes */ text-align: center;}#yourdiv { background-color: red; /* for visualization purposes */ display: inline-block;}
<div id="wrapper"> <div id="yourdiv">Your text</div></div>

.container { text-align: center;}
<div class='container'> <button>MyBtn1</button> <button>MyBtn1</button> <button>MyBtn1</button> </div>
Bootstrap Center Vertical and Horizontal Alignment
Bootstrap 5 (Updated 2021)
Bootstrap 5 is still flexbox based so vertical centering works the same way as it did in Bootstrap 4. For example, align-items-center
(flex-direction: row) and justify-content-center
(flex-direction: column) can used on the flexbox parent (row or d-flex).
Centering examples in Bootstrap 5
Vertical center (don't forget the parent must have a defined height!):
my-auto
for centering inside flex (.d-flex
) elementsmy-auto
can be used to center columns (.col-
) insiderow
align-items-center
to center columns (col-*
) insiderow
Horizontal center:
text-center
to centerdisplay:inline
elements & column contentmx-auto
for centering inside flex elementsmx-auto
can be used to center columns (.col-
) insiderow
justify-content-center
to center columns (col-*
) insiderow
Bootstrap 4.3+ (Update 2019)
There's no need for extra CSS. What's already included in Bootstrap will work. Make sure the container(s) of the form are full height. Bootstrap 4 now has a h-100
class for 100% height...
Vertical center:
<div class="container h-100">
<div class="row h-100 justify-content-center align-items-center">
<form class="col-12">
<div class="form-group">
<label for="formGroupExampleInput">Example label</label>
<input type="text" class="form-control" id="formGroupExampleInput" placeholder="Example input">
</div>
<div class="form-group">
<label for="formGroupExampleInput2">Another label</label>
<input type="text" class="form-control" id="formGroupExampleInput2" placeholder="Another input">
</div>
</form>
</div>
</div>

the height of the container with the item(s) to center should be 100%
(or whatever the desired height is relative to the centered item)
Note: When using height:100%
(percentage height) on any element, the element takes in the height of it's container. In modern browsers vh units height:100vh;
can be used instead of %
to get the desired height.
Therefore, you can set html, body {height: 100%}, or use the new min-vh-100
class on container instead of h-100
.
