HTML & Body Tags
All HTML files must be wrapped in <html></html> tags. This tells the browser that the file is an HTML file.
Anything visible on screen should be wrapped in the <body></body> tags. Otherwise, you may experience problems with things not appearing in certain browsers.
Later on, we’ll learn about the <head></head> tags.
Should I use VSCode or Atom or something else?
Where you write your code (aka your development environment) is a personal choice. Choose whatever you’re most comfortable with.
I recommend VSCode as it’s the most popular. But Atom is also a good choice.
In some companies, you’ll be forced to use a certain environment. This is usually because it makes ramping up new developers faster.
You can see my Atom tutorial here.
