How to Install Gallery CSS on macOS

Gallery CSS is a lightweight and customizable CSS gallery that allows you to build beautiful and interactive image galleries for your website. In this tutorial, we will guide you through the process of installing Gallery CSS on your macOS system.

Prerequisites

Before we begin, make sure you have the following prerequisites installed on your macOS system:

Steps

  1. Open the Terminal app on your macOS system.

  2. Install Gallery CSS by running the following command in the Terminal:

npm install -g gallery-css

This command will download and install the latest version of Gallery CSS globally on your system.

  1. Verify that Gallery CSS is installed by running the following command in the Terminal:
gallery-css --version

This command will display the version number of Gallery CSS that is currently installed on your system.

  1. Create a new directory for your Gallery CSS project by running the following command:
mkdir my-gallery

This command will create a new directory called "my-gallery" in your current directory.

  1. Navigate to the "my-gallery" directory by running the following command:
cd my-gallery

This command will change the current directory to "my-gallery".

  1. Create a new "index.html" file in the "my-gallery" directory by running the following command:
touch index.html

This command will create a new empty file called "index.html".

  1. Open the "index.html" file in a text editor of your choice and add the following code to it:
<!DOCTYPE html>
<html>
  <head>
    <title>My Gallery</title>
    <link rel="stylesheet" type="text/css" href="https://unpkg.com/gallery-css@1.0.2/dist/gallery.css" />
  </head>
  <body>
    <div class="gallery">
      <div class="gallery-item">
        <img src="https://picsum.photos/id/237/200/300" alt="Gallery Item 1" />
      </div>
      <div class="gallery-item">
        <img src="https://picsum.photos/id/238/200/300" alt="Gallery Item 2" />
      </div>
      <div class="gallery-item">
        <img src="https://picsum.photos/id/239/200/300" alt="Gallery Item 3" />
      </div>
      <div class="gallery-item">
        <img src="https://picsum.photos/id/240/200/300" alt="Gallery Item 4" />
      </div>
    </div>
  </body>
</html>

This code creates a basic Gallery CSS gallery with four items.

  1. Save the "index.html" file.

  2. Open the Terminal and navigate to the "my-gallery" directory (if you are not already there).

  3. Start a local web server by running the following command:

python -m SimpleHTTPServer

This command will start a web server on port 8000.

  1. Open a web browser and navigate to the following URL:
http://localhost:8000/

This will load the "index.html" file in your web browser and display the Gallery CSS gallery.

Congratulations, you have successfully installed Gallery CSS on your macOS system and created a basic gallery. You can now customize the gallery by modifying the HTML and CSS code in the "index.html" file.
