How to center an element vertically and horizontally with CSS?
To center an element vertically and horizontally with CSS, use the justify-content and align-items properties. We have used flex in our examples.
The Justify-content Property
In CSS, the justify-content property is used to align the items horizontally. The syntax of CSS justify-content property is as follows −
Selector {
display: flex;
justify-content: /*value*/
}
The following are the values −
flex-start − The flex items are positioned at the start of the container. This is the Default value.
flex-end − The flex items are positioned at the end of the container
center − The flex items are positioned in the center of the container
space-between − The flex items will have space between them
space-around − The flex items will have space before, between, and after them
space-evenly − The flex items will have equal space around them
The Align-items Property
In CSS, the align-items property is used to set the default alignment for flex-items in a flexbox. It aligns the items vertically.
Syntax
The syntax of CSS align-items property is as follows −
Selector {
display: flex;
justify-content: /*value*/
}
The following are the values −
stretch − The flex-items are stretched to fit the container
center − The flex-items are positioned at the center of the containe
flex-start − The flex-items are positioned at the beginning of the container
flex-end − The flex-items are positioned at the end of the container
Create an Element
Let's say we are aligning an element <h2>. The <h2> element is used to create a heading n a web page −
<h2>This text is centered vertically and horizontally both</h2>
Set the Element Inside a div
To center align a button, set the button element inside a div −
<div class="centered"> <h2>This text is centered vertically and horizontally both</h2> </div>
Style the div and Center Align
To center align vertically, use the align-items property. To center align horizontally, use the justify-content property. Set center for both the values −
.centered {
display: flex;
justify-content: center;
align-items: center;
height: 200px;
border: 3px solid rgb(0, 70, 128);
}

<!DOCTYPE html>
<html>
<head>
<style>

}
.centered {
