For those who are not familiar:
- HTML is your page's structure, such as the headers, the body text, any images you want to include. It defines the contents of a web page.
- CSS controls how that page looks (it's what you'll use to customize fonts, background colors, and so on).
- For those of you who are not familiar with HTML, this code might seem a bit alien. But it is perfectly understandable, even to web development beginners.
- <html> tag is required to define a HTML web page. <head> tag. The web page contents are defined inside the <body> tag.
