How to center a div using HTML and CSS.

Introduction

This blog is about how to center a div using CSS. There are various techniques available, and depending on the layout you are working with, some methods may be more suitable than others.

Before exploring it, you have to make sure that you have basic knowledge of HTML tags and CSS property and selectors for better understanding.

We will cover three different methods to center a div.

1. Using the Flex Property

Suppose we have a parent container and a child container and Inside the parent container we want to center a child container. so we can use the flexbox property.

HTML Code :

    <div class="parent-container">
        <div class="child-container">
        </div>
    </div>

CSS Code :

    <style>
        .parent-container{
            width: 600px;
            height: 600px;
            background-color: brown;
            display: flex;
            justify-content: center; /* centers vertically */
            align-items: center; /* centers horizontally */
        }
        .child-container{
            width: 150px;
            height: 150px;
            background-color: azure;
        }
    </style>

2. Using the Transform Property

You can also use the transform property to center an element. This method involves using margin and transform to adjust the position.

HTML Code :

    <div class="parent-container">
        <div class="child-container">
        </div>
    </div>

CSS Code :

    <style>
        .parent-container{
            width: 600px;
            height: 600px;
            background-color: brown;
            position: relative; /* Needed for absolute positioning */
        }
        .child-container{
            width: 150px;
            height: 150px;
            background-color: azure;
            position: absolute;
            margin-top: 50%; /* Pushes the child 50% down */
            margin-left: 50%; /* Pushes the child 50% right */
            transform: translate(-50%, -50%);
            /* Adjusts the child back to center */
        }
    </style>

3. Using the Grid Property

Another efficient way to center a div is by using CSS Grid.

HTML Code :

    <div class="parent-container">
        <div class="child-container">
        </div>
    </div>

CSS Code :

    <style>
        .parent-container{
            width: 600px;
            height: 600px;
            background-color: brown;
            display: grid;
            place-items: center; /* Centers both horizontally and
            vertically */
        }
        .child-container{
            width: 150px;
            height: 150px;
            background-color: azure;
        }
    </style>
