Answer 1

CSS stands for Cascading Style Sheets. From the term itself, what it does is provide styling for webpages. It's the reason webpages look nice and clean instead of boring and bland! BlueJ has it because it supports editing for CSS along with HTML and JS, so you can also use it for web development!
