Final answer:
To run an HTML file in Visual Studio Code, utilize the 'Open with Live Server' feature by right-clicking on the code, or manually open the file in a web browser from the file explorer.
Step-by-step explanation:
To run an HTML file in Visual Studio Code, you must first ensure that you have a web browser installed on your computer. After opening the HTML file in Visual Studio Code, you can right-click on the code or preview area and select 'Open with Live Server' to view the file in your default browser.
This requires the Live Server extension, which can be installed from the Visual Studio Code Marketplace. Without this extension, you can also right-click on the file in the Visual Studio Code's explorer area and select 'Reveal in File Explorer' to navigate to the file location. From there, you can double-click the file or right-click and choose 'Open with' to launch it in any installed browser. Remember that you will need to refresh the browser manually to see changes if you are not using the Live Server extension.
