What is Cascading Style Sheet?

 

Cascading Style Sheets, commonly referred to as CSS, is a style sheet language used to describe the presentation of a document written in HTML (Hypertext Markup Language) or XML (Extensible Markup Language). It is responsible for controlling the visual appearance of web pages and user interfaces.

 

CSS separates the content of a webpage from its presentation, allowing web designers and developers to define various aspects of the page's layout, typography, colors, and other visual elements. By using CSS, you can apply consistent styles and formatting to multiple web pages at once, making it easier to maintain and update the design across an entire website.

 

The term "cascading" in CSS refers to the way styles are applied to HTML elements. Multiple CSS rules can target the same HTML element, and the styles will be combined and applied according to a specific hierarchy and precedence. This allows for flexibility and the ability to override or inherit styles as needed.

 

CSS is based on a set of rules and selectors that define which elements in an HTML document should receive specific styles. These styles are defined using properties and values, which control attributes such as the font, color, size, margin, padding, and positioning of elements.

 

CSS has evolved over time, and there are different versions with varying levels of features and capabilities. CSS3, for example, introduced new properties, selectors, and techniques, including support for animations, transitions, and responsive design.

 

Overall, CSS is a fundamental technology in web development that plays a crucial role in creating visually appealing and engaging websites and applications.
