HTML Preview on GitHub Pages

Ever found yourself in a situation where you wanted to preview your HTML code, but didn't have a local server or browser to display it? GitHub's HTML preview feature on GitHub.io comes to the rescue. This built-in functionality allows you to quickly preview your HTML code directly from your GitHub repository. Let's delve into how you can use this feature and explore some of its benefits.

Before we dive in, ensure that your HTML code is in a repository on GitHub. If you haven't already, push your code to a GitHub repository. Once your code is there, you're ready to preview it using GitHub.io.

Understanding GitHub.io

GitHub.io is a static site hosting service provided by GitHub. It's designed to host your personal or project websites directly from your GitHub repository. By default, GitHub.io serves your website from the gh-pages branch of your repository. However, you can also serve your website from the root (master or main) branch or any other branch.

Now that we've covered the basics of GitHub.io, let's look at how to preview your HTML code using this service.

Previewing HTML Code from the Root Branch

If your HTML code is in the root branch (usually main or master), you can preview it by navigating to https://.github.io//. Replace with your GitHub username and with the name of your repository. For example, if your username is 'johndoe' and your repository is 'my-website', the URL would be https://johndoe.github.io/my-website/.

This will display your HTML code as a web page. If you've linked your HTML file correctly, you should see your website live and in action.

Previewing HTML Code from Other Branches

If your HTML code is in a branch other than the root branch, you can still preview it using GitHub.io. To do this, you'll need to create a .github.io repository and link it to your main repository. Here's how:

Create a new repository named .github.io.
In your main repository, create a new file named CNAME (all caps) in the root directory. This file should contain the custom domain you want to use for your website, without the 'www' or 'http' prefixes. For example, if your custom domain is 'www.example.com', the CNAME file should contain 'example.com'.
Commit and push the CNAME file to the branch you want to preview.
Go to the settings page of your main repository. Scroll down to the 'GitHub Pages' section and select the branch you want to preview from the 'Source' dropdown. Click 'Save'.

Now, you can preview your HTML code by navigating to https://.github.io//. Replace with the name of the branch you're previewing. For example, if you're previewing the 'dev' branch, the URL would be https://johndoe.github.io/dev/.
