Part-1 link

  1. First we have to create a Project Directory TheGhostHunter.

  2. Create 3 directories (folders)

    1. assets This folder for storing all resources like images, fonts etc.
    2. css This folder for storing all stylesheets related with html files.
    3. js This folder for storing all javascripts related with html files.

  3. Create a file called index.html in TheGhostHunter (called root directory for this project).

Folder-Structure

For code editing you can use your favorite IDE. I am using Visual Studio Code.

  1. In assets folder create a folder images.
  2. Then create a 4 folders in images folder.
    1. background
    2. characters
    3. icons
    4. typefaces

Folder-Structure

  1. You can find the images here. image_folder

Codes:

1. index.html (in root folder)
