In Web development, division is commonly achieved using the <div>
element. A <div>
is a block-level container that can hold various types of content and can be styled using CSS. This guide will explain how to use <div>
elements and style them with CSS to create well-structured web pages.
What is a <div> Element?
The <div>
element is a generic container for grouping and styling content. It does not have any special meaning or behavior on its own, but it becomes powerful when combined with CSS.

Using <div> for Layout
The <div>
element is often used to create sections or divisions of content on a web page. For example, you might use <div>
elements to separate the header, main content, and footer of a page.
<div class="header">
<h1>Welcome to My Website</h1>
</div>
<div class="main-content">
<p>Here is some main content.</p>
</div>
<div class="footer">
<p>Footer information goes here.</p>
</div>
Styling <div> Elements with CSS
Using CSS, you can style <div>
elements to create visually appealing layouts. Here are some common properties you might use:
Background Color
You can change the background color of a <div>
using the background-color
property.
.header {
background-color: lightblue;
}
.main-content {
background-color: lightgreen;
}
.footer {
background-color: lightcoral;
}
Padding and Margin
Padding adds space inside the <div>
, while margin adds space outside the <div>
.
.header, .main-content, .footer {
padding: 20px;
margin: 10px 0;
}
Width and Height
You can set the width and height of a <div>
using the width
and height
properties.
.main-content {
width: 80%;
height: 200px;
}
Border
You can add a border around a <div>
using the border
property.
.footer {
border: 2px solid black;
}
Example: Styled Divisions
Let's put it all together with an example of a simple webpage layout using styled <div>
elements:
<!DOCTYPE html>

<head>
<title>My Simple Layout</title>
<style>
.header {
background-color: lightblue;
padding: 20px;
