How To Make Body Of A Window Full Height Css

CSS Programming

Hey there! Today I’m going to show you how to make the body of a window full height using CSS. This is a handy technique to know, especially if you want to create a fullscreen layout for your website. Let’s dive right in!

Understanding the Basics

Before we jump into the code, let’s get a basic understanding of the concept. When we talk about making the body of a window full height, we’re essentially looking to fill the entire viewport, regardless of how much content is on the page. This creates a seamless and immersive experience for the user.

The CSS Approach

To achieve this effect, we’ll be using CSS properties. The first thing we need to do is set the height of the html and body elements to 100%. This will make these elements take up the full height of the viewport.

html, body {
height: 100%;

Next, we’ll need to remove any default margins or paddings applied to the body element. This ensures that our content is positioned flush against the edges of the viewport.

body {
margin: 0;
padding: 0;

Now that we have the basic setup, we can start styling our layout. One common approach to creating a full-height body is to use a flexbox container. By setting the display property of the body element to flex, we can easily align our content vertically within the viewport.

body {
display: flex;
flex-direction: column;

Next, we’ll want to make sure that the content fills the available space. To do this, we can set the flex property of the content container to 1. This will make it expand to take up any remaining space in the parent container.

.content {
flex: 1;

Lastly, don’t forget to add some styles to your content container and any other elements you may have on the page. This is where you can get creative and add your own personal touches to make the design unique.


And there you have it! With just a few lines of CSS, you can make the body of a window full height. This technique is incredibly useful for creating fullscreen layouts that provide a rich and immersive experience for your users. So go ahead, give it a try and let your creativity run wild!
