benefits of serving static files on another domain 
1. Using another domain name means that you'll be able to not have the cookies that are used on the main domain - which means that HTTP requests will be smaller
2. No need for a full PHP/.NET/JAVA server to serve static content!
3. Use another machine to serve the static content (Including some CDN) 
4. Use another web-server to serve the static content (something more lightweight and faster)

basic HTML snippet in different IDEs
Sublime Text: by typing 
<ht
autocomplete will appear and after pressing enter, inserts the following basic HTML:
<!DOCTYPE html>
<html>
<head>
	<title></title>
</head>
<body>

</body>
</html>
In VS Code, after typing 
!
will be inserted the following HTML:
<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <meta name="viewport" content="width=device-width, initial-scale=1.0">
    <title>Document</title>
</head>
<body>
    
</body>
</html>
