What is CSS?
CSS stands for Cascading Style Sheets. It is a programming language used to describe the visual appearance and formatting of a document written in HTML (Hypertext Markup Language) or XML (eXtensible Markup Language). CSS allows web designers and developers to control the layout, colors, fonts, and other aspects of the presentation of a web page.
With CSS, you can define various styles and apply them to different elements of a webpage, such as headings, paragraphs, links, images, and more. By separating the content (HTML) from its presentation (CSS), you can achieve consistent and uniform styling across multiple web pages, making it easier to maintain and update the design of a website.
CSS works by selecting HTML elements using selectors and applying style declarations to those elements. Selectors can target elements based on their tag name, class, ID, or other attributes. Style declarations consist of property-value pairs, where properties define the visual characteristics, such as color or font-size, and values determine the specific settings for those properties.
CSS also supports inheritance and cascading, which means that styles can be inherited by child elements from their parent elements, and multiple styles can be applied to the same element with varying levels of specificity. This allows for flexibility and customization in designing web pages.
Overall, CSS is a fundamental technology for web development, providing control over the visual aspects of a webpage and enabling the creation of attractive and responsive designs.
