1. Update one of the HTML or CSS files for your website.
2. Upload this file to your GitHub repository.

Note: if the file you updated is inside a folder, open that folder in your GitHub repository first, then upload the file. For example, if you have a file called styles/header.css, open the styles folder in GitHub first, then click Add file > Upload files.


This will replace the existing file in the repository with your updated version.

3. Wait a few minutes for GitHub Pages to process the updated file.
After that, your website should be updated.
