Note: For the purposes of this lesson, you should save all the files you create in your text editor with .html as your file extension—for example, "my_first_web_page.html".

How do I learn to code in HTML and CSS on my Mac? Web design is one of the most useful skills you can learn, and it’s easy to learn HTML and CSS (the two main pillars of web pages) in Mac OS X.

If you need to create a Web page fast and don't want to waste time downloading and installing a complex HTML editor, you can use Word, the word processor included in the Microsoft Office 2010 suite.

By default, Word 2016, as well as Word 365, saves the page with a ".htm" file extension, but you can change this to ".html" if you prefer. Both extensions work as HTML files.
