HTML (Hypertext Markup Language) is the standard language used to create web pages. It is a markup language, which means that it uses tags to describe the structure and content of a web page. HTML tags define the headings, paragraphs, lists, links, images, and other elements of a web page.
CSS (Cascading Style Sheets) is a stylesheet language used for describing the look and formatting of a web page. CSS is used to control the layout, colors, fonts, and other visual aspects of a web page, separate from the HTML content. CSS makes it easy to maintain a consistent look and feel across multiple pages of a website.
JavaScript is a scripting language that allows you to create dynamic and interactive web pages. JavaScript is used to add interactivity to a web page, such as responding to user actions, updating content on the fly, and creating animations. JavaScript is typically used in combination with HTML and CSS to create dynamic and engaging web pages.
Together, HTML, CSS, and JavaScript form the backbone of the modern web, and are essential skills for web developers. HTML provides the structure and content of a web page, CSS provides the visual styling, and JavaScript provides the dynamic interactivity.
