About CSS css tutorial

In this lesson, we will learn about CSS in a step-by-step process. From its definition to its application, and why should we learn the CSS.

What is CSS?

CSS stands for Cascading Style Sheets. It is a styling language used to describe the appearance and formatting of a document written in HTML. With CSS, you can control the layout, colors, fonts, and other visual aspects of a web page.

CSS works by associating styles with HTML elements, defining how they should be presented in the browser.


Who developed CSS?

CSS was developed by Hakon Wium Lie and Bert Bos. They began working on CSS in 1994 and presented the first CSS draft specification in 1995. The official CSS specification was published in December 1996 by the World Wide Web Consortium (W3C).

Why is CSS important?

CSS plays a crucial role in web development for several reasons:

  • Separation of concerns: CSS allows you to separate the presentation (styling) from the structure (HTML) and behavior (JavaScript) of a web page. This separation makes code maintenance and updates much easier.
  • Reusability: With CSS, you can define styles and reuse them across multiple elements or pages, saving time and effort.
  • Flexibility: CSS provides a wide range of styling options and techniques, allowing you to create visually appealing and responsive designs.
  • Browser compatibility: CSS helps ensure consistent rendering across different web browsers, improving the user experience.
