Getting Started

What is CSS?

CSS (Cascading Style Sheets) is a stylesheet language used to describe the presentation of a document written in HTML.
It defines how elements should be rendered on screen, paper, speech, or other media.

How CSS Works

CSS works by selecting HTML elements and applying styles to them.
The "cascading" part refers to how styles can inherit and override each other based on specificity and order.

• A text editor (VS Code, Sublime Text, Notepad, etc.)
• A web browser (Chrome, Firefox, Safari, etc.)
