Details
To create a new HTML file in VS Code, click the New File button to create a new file and then save it. In the dialog that pops up, give it a name and add the .html file extension at the end.
The home page for your website is usually given the name of index.html. Other HTML files for a website can have more descriptive names, like about.html or contact.html.
If your file name needs to contain multiple words, use hyphens to separate the words, like about-us.html or contact-us.html.
Exercises
Create an index.html file in the creating-html-files folder. Then, try creating an about.html file as well.
