Introduction

This tutorial provides a clear and concise guide to developing an image gallery using CSS. An image gallery displays a collection of images, allowing users to view them in an organized and visually appealing manner.

Key Concepts

1. HTML Structure

• The image gallery is constructed using HTML elements.
• A common structure involves utilizing <div> containers for the gallery and <img> tags for each image.

2. CSS Styling

• CSS styles the gallery, enhancing its visual appeal.
• Key CSS properties include:
  • display: Controls the layout (e.g., flex, grid).
  • margin: Adds space around elements.
  • border: Creates borders around images.
  • hover effects: Alters appearance when users hover over an image.

3. Responsive Design

• The gallery should be responsive, adapting to various screen sizes.
• Use percentages for widths and media queries to modify styles based on screen size.

Example Code

<div class="gallery">
    <img src="image1.jpg" alt="Image 1">
