It’s great that we’ve added all this style to “lounge.html”, but what about “elixir.html” and “directions.html”? They need to have a look that is consistent with the main page. Easy enough... just copy the style element and all the rules into each file, right? Not so fast. If you did that, then whenever you needed to change the style of the site, you’d have to change every single file – not what you want. But, luckily, there is a better way. Here’s what you’re going to do:
Take the rules in “lounge.html” and place them in a file called “lounge.css”.
Create an external link to this file from your “lounge.html” file.
Create the same external links in “elixir.html” and “directions.html”.
