CSS: How to Add a Background Image from a Folder

Adding a background image to your website can make it visually appealing and engaging. CSS makes it simple to set an image from a folder as the background of an element, such as a <div>, <section>, or even the whole page.

In this blog post, you’ll learn:

• ✅ How to set a background image using CSS
• ✅ How to properly reference an image from your local folder
• ✅ Best practices for styling and positioning
• 🧪 Practical examples to try yourself

✅ 1. File Structure Example

Before writing CSS, let’s understand a typical project structure:

my-project/
├── index.html
├── styles/
│   └── style.css
└── images/
    └── background.jpg

In this setup:

• Your HTML file is in the root folder
• Your CSS file is in the styles/ folder
• Your background image is in the images/ folder

✅ 2. Add Background Image with CSS

To add an image as a background:

✅ CSS (style.css):

body {
  background-image: url("../images/background.jpg");
  background-size: cover;
  background-repeat: no-repeat;
  background-position: center;
}

✅ Explanation:

• url("../images/background.jpg"): path from CSS file to image
• background-size: cover;: scales the image to cover the entire element
• background-repeat: no-repeat;: prevents the image from repeating
• background-position: center;: centers the image inside the element

✅ 3. Apply Background to a Specific Element

You can also apply the background to a specific container:

<div class="hero-section"></div>

.hero-section {
  height: 400px;
  background-image: url("../images/hero-bg.jpg");
  background-size: cover;
  background-position: center;
}

✅ This is great for banners, hero sections, cards, or footer backgrounds.

🧪 Quick Tip: Relative Path Explained

If your CSS file is in styles/ and your image is in images/, you use:

url("../images/image-name.jpg")

The ../ tells CSS to go up one folder, then look in the images/ folder.
