Follow these steps to host your new interactive file online for free using GitHub Pages.
1 Create a GitHub Account & Repository
If you don't have a GitHub account, sign up for free. Then, create a new repository by clicking the "+" icon in the top-right and selecting "New repository". Name it something like `my-portfolio`.
2 Upload Your File
In your new repository, click the "Add file" button and choose "Upload files". Drag and drop the downloaded HTML file into the designated area and click "Commit changes".
3 Enable GitHub Pages
Go to your repository's "Settings" tab. In the left sidebar, click on "Pages". Under "Branch", select `main` from the dropdown menu and click "Save".
4 Share Your Live Page!
GitHub will provide you with a public URL (like `https://your-username.github.io/my-portfolio/your-file.html`). It might take a minute or two to go live. Once it's ready, you can share this link with anyone!
