HTML is the standard markup language for creating web pages. CSS is a style sheet language used for describing the presentation of a document written in a markup language. A style sheet is a collection of rules that tells a web browser how to display a document written in HTML or XML.
HTML is easy to learn - you just need to understand how the tags work and what they are used for. CSS is a bit more tricky, but once you get the hang of it, it is also easy to use.
Web browsers interpret HTML and CSS code in order to display web pages. Anyone can learn HTML and CSS, and there are many resources available online to help you get started.
