How to Change the Background Color in CSS

Author:

Introduction

Changing the background color of an element is one of the most common tasks in CSS. The background-color property allows you to easily set the background color of any HTML element.

Problem Statement

Create a CSS code that:

  • Changes the background color of specific elements using the background-color property.
  • Demonstrates different ways to define colors (named colors, HEX, RGB, HSL).

Example:

  • Input: A div element with the text "Background Color Example".
  • Output: The background color changes based on the specified CSS.

Solution Steps

  1. Target the HTML Element: Choose the element whose background you want to change (e.g., div, body, etc.).
  2. Use the background-color Property: Apply the background-color property with your chosen color format.

HTML Structure

<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <meta name="viewport" content="width=device-width, initial-scale=1.0">
    <title>Change Background Color</title>
    <style>
        /* Step 2: Change background color using a named color */
        .background-named {
            background-color: lightblue;
        }

        /* Change background color using HEX value */
        .background-hex {
            background-color: #ff6347; /* tomato */
        }

        /* Change background color using RGB value */
        .background-rgb {
            background-color: rgb(60, 179, 113); /* mediumseagreen */
        }

        /* Change background color using HSL value */
        .background-hsl {
            background-color: hsl(120, 100%, 75%); /* light green */
        }
    </style>
</head>
<body>

    <div class="background-named">This background is lightblue (named color).</div>
    <div class="background-hex">This background is tomato (HEX color).</div>
    <div class="background-rgb">This background is mediumseagreen (RGB color).</div>
    <div class="background-hsl">This background is light green (HSL color).</div>

</body>
</html>

Explanation

Step 1: Target the HTML Element

  • We apply the background-color property to different <div> elements.

Step 2: Use the background-color Property

  • Each div element uses a different color format (named, HEX, RGB, HSL) to demonstrate multiple ways to set the background color.
