HTML (HyperText Markup Language) is a programming language designed for web development. It is commonly used to create the structure and features of websites. HTML files are saved with the ".HTML" extension. Modern browsers, including Google Chrome, Safari, and Mozilla Firefox, all recognize this format and can open these files. Therefore, to run an HTML file, you simply need to open it in your preferred browser.
Steps
Save as an HTML File

Understanding HTML HTML stands for Hypertext Markup Language. HTML files are text files that describe the content and layout of a webpage. You can use any text editor (such as Notepad, Notepad++, or a specialized HTML editor) to view these files. However, to see how the page appears, you need to open it in a browser – a program designed to interpret and render HTML files.

Write or Paste HTML into a Basic Text Editor. As you improve your coding skills, you might opt for specialized HTML editors like Adobe Dreamweaver, Microsoft Expression Web, or CoffeeCup HTML Editor. However, for beginners, a simple program such as Notepad (Windows) or TextEdit (Mac) is all you need.

Save the File as your_file_name.html. When creating an HTML file using Notepad, TextEdit, or any other text editor, remember to save it with the correct extension. Before saving, make sure to change the 'Save as type' option to 'All Files' and click 'Save.'
Run the HTML File

Ensure a Web Browser is Installed on Your Computer. To run an HTML file on your computer, you must have a web browser installed first.

Locate the Saved File. If you believe the file is in a particular folder but can't find it, try searching for it on your computer. Type your_file_name.html into the search box at the bottom of the Start menu (Windows) or in the Finder search bar (Mac).
- The folder containing the HTML file may share the same name, but without the .html extension. It could also contain .js, . files, images, and other necessary files. These are important for the layout and functionality of the website. To display the site properly, these files must be in the same folder as the HTML file. If you wish to edit the HTML file, you will need to learn how to code using HTML and other programming languages.

Right-click (Windows) or double-click (Mac) on the file and select 'Open with' from the action menu. While your default browser will be listed at the top, you can choose any other browser installed on your computer. You can open the file with Google Chrome, Mozilla Firefox, Safari, etc.
- Most computers automatically associate the default browser with the .html extension, meaning you typically don’t need to search for a browser to open it. You can simply double-click the file, and it will open in your default browser.
- If your computer doesn’t recognize the HTML file, Windows will ask whether you want to open it with a pre-installed app or search for the extension online. Choose 'open using already installed applications,' and you’ll be able to pick from available browsers.

View the HTML file with the browser you selected. The browser will automatically interpret and display your code. The location of the file will be shown in the address bar, confirming that it is indeed the file you intended to open, not another one.

Alternative Method: Open the browser and press Ctrl-O. The 'Open' menu will appear. Find and double-click the file, and it will open in a new browser tab. Different browsers may have different hotkeys for the 'Open' menu. To find the exact shortcut, check your browser’s settings.
Run the HTML file for a website

Open your preferred FTP platform. If the server has an existing FTP platform, use it as it will make things much simpler. If not, you can use a third-party FTP service like FileZilla.

Next, connect to the standalone server (your website server). If you are using a pre-built platform, you don’t need to worry about this. You will see two boxes on the left side and two boxes on the right side of the screen. Don't worry about the two left boxes or the one on the upper right—just focus on the remaining box.

Locate the HTML file and drag it into the designated box. The upload process will begin immediately. For pre-built platforms, navigate to the 'htdocs' folder (or the default HTML folder) and click 'Upload.' A few options will then be presented for you to choose from.
- Do not use shortcuts! The LNK Mirror file will be uploaded even if you don’t intend to.

Wait for the file to finish uploading. Once it’s done, if you remove the default page, you can visit the website and see your HTML file! If a menu appears, click on the .html file to view it.
Advice
- For a smoother experience, it is recommended to use a browser better than Internet Explorer 7.
