HTML (Hypertext Markup Language):
HTML, or Hypertext Markup Language, is the standard markup language used to create and design documents on the World Wide Web. It provides the basic structure of a web page by using a system of elements and tags to define different parts of the content. These elements include headings, paragraphs, images, links, forms, and more. HTML is essential for structuring web content and is the backbone of any webpage. It allows browsers to interpret and display the content properly, forming the foundation of web development.
CSS (Cascading Style Sheets):
CSS, or Cascading Style Sheets, is a style sheet language used to describe the presentation of a document written in HTML. While HTML provides the structure of a webpage, CSS is responsible for its visual presentation. CSS enables web developers to control the layout, colors, fonts, and spacing of HTML elements, enhancing the overall appearance and aesthetics of a website. It operates by selecting HTML elements and applying styles to them, either directly within an HTML document or through external style sheets. CSS is crucial for creating visually appealing and responsive web designs. The term "cascading" refers to the way styles are applied, with rules from different sources combining to determine the final appearance.
