What isCascading Style Sheets

Cascading Style Sheets (CSS) is a powerful language used to define and control the look and formatting of a document written in HTML or XML. It allows web developers to separate the content of a webpage from its presentation, making web pages more accessible, flexible, and reusable. With CSS, you can easily specify layout, colors, fonts, and other style elements that make up the overall visual design of a website.

Core Language of the Open Web

CSS, along with HTML and JavaScript, is a cornerstone of the technology that powers the World Wide Web. It is standardized for all web browsers according to the W3C specifications, ensuring that developers can create beautiful and consistent web pages across different platforms and devices. In the past, different parts of the CSS specification were developed synchronously, which allowed versioning of the latest recommendations, such as CSS1, CSS2.1, or even CSS3.

Benefits of Using CSS

The separation of content and presentation provided by CSS brings several benefits to web developers. It allows for greater accessibility of content, as screen readers and other assistive technologies can understand the logical structure of the document without being distracted by its formatting. It also provides more flexibility and control in specifying presentation features, allowing for animations, responsive design, and other effects that make web pages more engaging and interactive.

By keeping the style information in a separate .css file, you can easily apply the same formatting to multiple web pages, reducing complexity and repetition of structural content. Finally, caching the .css file helps to improve the loading speed of web pages that share the file and its formatting.
