Did You Know?
The first version of HTML was created by Tim Berners-Lee in 1993 and contained only 18 tags.
HTML (HyperText Markup Language) is the standard language used to create the structure of web pages. It uses a series of elements and tags to tell the browser how to display content like text, images, and links. As web applications grow, HTML files can become deeply nested and difficult to read. Formatting is essential because it visually represents the hierarchy of these elements, which is vital for developer productivity and long-term project maintenance.
Best Practice
Always use a consistent number of spaces for indentation (usually 2 or 4) to ensure your code is readable across different editors.
Q: Does this tool handle embedded CSS and JavaScript? A: Yes, our formatter is designed to intelligently indent <style> and <script> tags within your HTML document.
Q: Will it fix my broken HTML tags? A: This tool is a formatter, not a repair tool. While it organizes code, we recommend using our HTML Validator to find and fix structural errors.
Q: Is there a limit to how much code I can paste? A: There is no hard limit, though extremely large files may be limited by your browser's available memory.
