What is HTML file format?

HTML (Hypertext Markup Language) is the fundamental markup language that powers the creation of web pages. It serves as the building block for websites and is responsible for structuring the content, including text, images, audio, and video. HTML, in conjunction with CSS (Cascading Style Sheets), forms the backbone of digital documents on the internet.

In web development, HTML files work hand in hand with CSS files to create visually appealing and well-organized web pages. HTML files contain the markup that defines the structure of the document, while CSS files handle the styling and formatting of the HTML elements. HTML markup is written using tags, which instruct the web browser on how to interpret and display the content. Common HTML tags include HEAD, BODY, TITLE, H1, and P. HTML files are typically saved with a .html file extension and can be opened in web browsers, where they are rendered as web pages. They can also be viewed and edited using text editors like Notepad++ or Sublime Text.

The collaboration between HTML and CSS is essential for creating appealing and functional web pages. HTML provides the underlying structure, defining the layout, headings, paragraphs, links, and other elements that make up a webpage. CSS, on the other hand, allows developers to apply styling rules and visual enhancements, such as colors, fonts, margins, and positioning, to the HTML elements. This separation of structure (HTML) and presentation (CSS) enables efficient design changes and consistent styling across multiple web pages.

HTML is the cornerstone of the web, enabling the creation of interactive and accessible content that can be viewed in web browsers. It forms the foundation for other web technologies, such as JavaScript, which adds interactivity and dynamic behavior to web pages. HTML’s standardized syntax and wide browser support make it a universal language for web development.
