CSS Central, Horizontal and Vertical Alignment

CSSWeb DevelopmentFront End Technology

We can align an element or the content inside it by using CSS which provides various options for alignment of an element and its content horizontally, vertically or in center.

Horizontal Alignment

  • Inline-elements

    Inline elements or inline-block elements such as text, anchor, span, etc. can be aligned horizontally with the help of CSS text-align property.

  • Block-level elements

    Block-level elements such as div, p, etc. can be aligned horizontally with the help of CSS margin property, but width of element should not be 100% relative to the parent as then it wouldn’t need alignment.

  • Block-level elements using float or position scheme

    Elements can be aligned horizontally with the help of CSS float property which aligns multiple elements to either left/right and not in center or using CSS positioning scheme absolute method.

Example

Let’s see an example of CSS horizontal alignment −

 Live Demo

<!DOCTYPE html>
<html>
<head>
<title>CSS Horizontal Alignment</title>
<style>
.screen {
   padding: 10px;
   width: 70%;
   margin: 0 auto;
   background-color: #f06d06;
   text-align: center;
   color: white;
   border-radius: 0 0 50px 50px;
   border: 4px solid #000;
}
.seats span, .backSeats div{
   margin: 10px;
   padding: 10px;
   color: white;
   border: 4px solid #000;
}
.seats span{
   width: 120px;
   display: inline-block;
   background-color: #48C9B0;
}
.left{
   text-align: left;
}
.right{
   text-align: right;
}
.center{
   text-align: center;
}
.seats{
   text-align: center;
}
.backSeats div {
   background-color: #dc3545;
}
.leftFloat{
   float: left;
}
.rightAbsolute{
   position: absolute;
   right: 150px;
}
</style>
</head>
<body>
<div class="screen">Screen</div>
<div class="seats">
<span class="left">Adam</span>
<span class="center">Martha</span>
<span class="right">Samantha</span>
<div class="backSeats">
<div class="leftFloat">Premium 1</div>
<div class="leftFloat">Premium 2</div>
<div class="rightAbsolute">Premium 3</div>
</div>
</div>
</body>
</html>

Output

This will produce the following output −

Vertical Alignment

  • Inline-elements

    Inline elements or inline-block elements such as text, anchor, etc. can be aligned vertically with the help of CSS padding, CSS line-height, or CSS vertical-align property.

  • Block-level elements

    Block-level elements such as div, p, etc. can be aligned vertically with the help of CSS margin property, CSS flex property along with CSS align-items, or with positioning scheme method absolute with CSS transform property.
