Cascading Style Sheets, fondly referred to as CSS, is a simply
designed language intended to simplify the
process of making web pages presentable. CSS allows you to apply styles to web pages. More importantly, CSS
enables you to do this independently of the HTML that makes up each web page. It describes how a webpage
should look: it prescribes colours, fonts, spacing, and much more. In short, you can make your website look
however you want.

JavaScript is a programming language that was initially created to “make web pages alive” . It is widely
used for web development and is a core technology of the World Wide Web, alongside HTML and CSS. JavaScript
is a lightweight, cross-platform, single-threaded, and interpreted compiled programming language . It is a
“safe” programming language that does not provide low-level access to memory or the CPU, because it was
initially created for browsers which do not require it.
Node.js is a cross-platform, open-source JavaScript runtime environment that can run on Windows, Linux,
Unix, macOS, and more. Node.js runs on the V8 JavaScript engine, and executes JavaScript code outside a web
browser. Node.js lets developers use JavaScript to write command line tools and for server-side scripting.
It was created by Ryan Dahl in 2009 and is maintained by the OpenJS Foundation.
