HTML is Hypertext Markup Language. HTML allows web browsers display text, images, links, videos, and other media elements. HTML is composed of tags. Tags are enclosed in angle brackets (<>) and act as instructions to the browser on how to render the content. Every HTML document begins with the <!DOCTYPE html> declaration, which tells the browser that the document is an HTML file.
HTML tags are used to define the structure and semantics of a webpage. For example, the <h1> tag represents a top-level heading, <p> represents a paragraph, <img> is used to insert an image, and <a> creates a hyperlink. These tags can be nested within each other to create a hierarchical structure. Attributes provide additional information to HTML tags. They are specified within the opening tag and modify the behavior or appearance of the element. For instance, the <a> tag uses the href attribute to define the URL of the destination it links to. To get started with HTML, all you need is a text editor and a web browser. You can write HTML code in a plain text file, save it with the .html extension, and then open it in a browser to see the result. There are also more advanced tools and editors available that offer syntax highlighting, code completion, and live previews. Learning HTML is an essential step for anyone interested in web development. It provides the fundamental knowledge needed to create well-structured and accessible web pages. With HTML, you have the power to transform your ideas into beautiful and functional websites. HTML provides the structure, while CSS adds the presentation. By separating the structure and presentation layers, CSS enables greater flexibility and easier maintenance of web pages. Styles can be applied to individual elements, groups of elements, or even the entire page.

CSS works by selecting HTML elements and applying specific style rules to them. Selectors are used to target elements based on their tags, classes, or IDs. For example, the selector h1 targets all <h1> tags, while .container targets elements with the class “container.” Properties define the visual characteristics of the selected elements. They can control attributes such as color, size, padding, margin, background, and more. For instance, the color property sets the text color, and the font-family property defines the font used for the selected elements. CSS styles can be specified directly within an HTML document using the <style> tag, but it’s more common to link an external CSS file to the HTML file. This separation of concerns allows for easier maintenance and reuse of styles across multiple pages. Modern CSS offers a wide range of features and capabilities, such as animations, responsive design, and grid layouts. It empowers developers to create visually stunning and engaging web experiences that adapt to different devices and screen sizes.

Both HTML and CSS are essential tools in web development. HTML provides the structure, while CSS adds the style and presentation. Understanding these languages and how they work together is crucial for anyone interested in creating and designing websites.
