What is CSS?
CSS (Cascading Style Sheets) 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. CSS is used to style all HTML tags, including the document’s body, headings, paragraphs, and other pieces of text. CSS can also be used to style the display of table elements, grid elements, and images. CSS is used by web developers to create websites that are both responsive and easy to maintain. CSS is an essential tool for modern web development.
