Organising locally on Your Computer:

1. Create a Project Folder:

   Start by creating a dedicated folder for your website project. Give it a clear and descriptive name.

2. Subfolders for Assets:

   Within your project folder, create subfolders to categorize different types of assets. Common subfolders may include:

   • Images:

     Store all image files used on the website in this folder.

   • CSS:

     Keep CSS files (stylesheets) in this folder. You can further organize them into subfolders if needed (e.g., for vendor styles, custom styles).

   • JavaScript:

     Store JavaScript files in this folder. Similar to CSS, you can organize them further if you have multiple scripts.

   • Fonts:

     If your website uses custom fonts, keep the font files in this folder.

   • Other:

     Create additional subfolders as needed for assets like audio or video files, downloadable documents, etc.

3. Naming Conventions:

   Use clear and consistent naming conventions for files to make them easy to identify and locate. Avoid spaces or special characters in file names, and use lowercase letters for better compatibility across different operating systems and web servers.

Organising within the Root Folder of the Website:

1. Mirror Structure:

   When uploading your website to a web server, maintain a similar folder structure to the one on your local computer. This makes it easier to manage and update the website.

2. Asset Compression and Optimization:

   Before uploading assets to the server, consider compressing images and minifying CSS and JavaScript files to reduce file sizes and improve website performance.

3. Relative Paths:

   Ensure that all asset links in your HTML, CSS, and JavaScript files use relative paths to point to the correct location of assets within the website's folder structure. This helps prevent broken links when moving or updating the website.

4. Robots.txt and .htaccess:

   Consider using a robots.txt file to control search engine indexing of certain assets and an .htaccess file for server-level configuration and optimization, such as caching and redirection rules.
