Introduction to CSS

CSS (Cascading Style Sheets) is a style sheet language used for describing the look and formatting of a document written in HTML or XML. CSS is a crucial part of web development as it provides a way to separate the content (HTML) from its presentation (CSS), making it easier to maintain and update the design of a website.

CSS gives web developers the ability to control the visual aspects of a web page, including font styles, colors, layouts, and more. With CSS, developers can create complex visual designs with a simple, clean code that is easy to read and understand.

The term "cascading" in CSS refers to the way styles are inherited from one element to another. If a style is not specified for a particular element, the style will be inherited from its parent element, and so on, until a style is found. This allows for a flexible and organized approach to styling a web page.

In short, CSS is an essential tool for creating visually appealing and user-friendly websites, and is a key component of modern web development.
