To horizontally center a block element (like <div>), use margin: auto;
To horizontally center a block element (like <div>), use margin: auto;
Setting the width of the element will prevent it from stretching out to the edges of its container.
The element will then take up the specified width, and the remaining space will be split equally between the two margins:
This div element is centered.
.center
{
margin: auto;
width: 50%;
border: 3px solid green;
padding: 10px;
}
width
property is not set
(or set to 100%).
To just center the text inside an element, use text-align: center;
This text is centered.
.center {
text-align: center;
border: 3px solid green;
}
To center an image, set left and right margin to auto
and make it into a block
element:
img
{
display: block;
margin-left: auto;
margin-right: auto;
width: 40%;
}
One method for aligning elements is to use position: absolute;
:
In my younger and more vulnerable years my father gave me some advice that I've been turning over in my mind ever since.
.right
{
position: absolute;
right: 0px;
width: 300px;
border: 3px solid #73AD21;
padding: 10px;
}
Another method for aligning elements is to use the float
property:
.right
{
float: right;
width: 300px;
border: 3px solid #73AD21;
padding: 10px;
}
Note: If an element is taller than the element containing it, and it is floated, it will overflow outside of its container. You can use the "clearfix hack" to fix this (see example below).
Then we can add the clearfix hack to the containing element to fix this problem:
.clearfix::after {
content: "";
clear: both;
display: table;
}
There are many ways to center an element vertically in CSS. A simple solution is to use top and bottom padding
:
I am vertically centered.
.center {
padding: 70px 0;
border: 3px solid
green;
}
To center both vertically and horizontally, use padding
and text-align: center
:
I am vertically and horizontally centered.
.center {
padding: 70px 0;
border: 3px solid
green;
text-align: center;
}
Another trick is to use the line-height
property with a value that is equal
to the height
property:
I am vertically and horizontally centered.
.center {
line-height: 200px;
height: 200px;
border: 3px solid green;
text-align: center;
}
/* If the text has multiple lines, add the
following: */
.center p {
line-height: 1.5;
display: inline-block;
vertical-align: middle;
}
If padding
and line-height
are not options, another solution is to use positioning and the transform
property:
I am vertically and horizontally centered.
.center {
height: 200px;
position: relative;
border: 3px solid green;
}
.center p {
margin: 0;
position: absolute;
top: 50%;
left: 50%;
transform: translate(-50%, -50%);
}
You can also use flexbox to center things. Just note that flexbox is not supported in IE10 and earlier versions:
I am vertically and horizontally centered.
.center {
display: flex;
justify-content: center;
align-items: center;
height: 200px;
border: 3px solid
green;
}
Use the margin property to make sure that the <div> element is center aligned according to its parent element.
<style> .intro { width: 200px; : ; } </style> <body> <div class="intro"> Lorem ipsum dolor sit amet,
consectetur adipiscing elit.
Phasellus imperdiet, nulla et dictum interdum,
nisi lorem egestas odio,
vitae scelerisque enim ligula venenatis dolor. </div> </body>
