Css (cascading stylesheet)

CSS (Cascading Style Sheets) is a programming language used for styling and formatting the visual presentation of web pages. It works in conjunction with HTML to separate the content of a web page from its design and layout. CSS allows developers to define the appearance of HTML elements, including colors, fonts, margins, padding, and more.

The primary goal of CSS is to provide a flexible and efficient way to control the visual aspects of a web page. By using CSS, you can create consistent and visually appealing designs, apply styles across multiple web pages, and easily make changes to the presentation without altering the underlying HTML structure.

CSS operates on a set of rules that target specific HTML elements or groups of elements. These rules consist of two main parts: a selector and a set of properties and values. The selector identifies the HTML element(s) to which the styles should be applied, while the properties and values determine how those elements should be styled.

CSS also provides a wide range of selectors, including element selectors, class selectors, ID selectors, and more, allowing you to target specific elements or groups of elements for styling. Additionally, CSS offers advanced features such as box model manipulation, layout control with flexbox and grid, animations, transitions, and responsive design techniques.

By separating the content and presentation layers, CSS promotes the reusability and maintainability of web pages, making it an essential tool for web developers and designers to create visually appealing and user-friendly websites.
