Frequently Asked Questions
What is HTML formatting?
HTML formatting is the process of organizing HTML code with proper indentation, line breaks, and spacing to make it more readable and maintainable. This includes adding consistent indentation, structuring nested elements clearly, and organizing attributes.
What's the difference between formatting and minifying?
Formatting (beautifying) adds structure and readability to code, while minifying removes all unnecessary characters (spaces, line breaks, comments) to reduce file size for production use.
Should I use spaces or tabs for indentation?
Both are acceptable, but spaces are more consistent across different editors and environments. Most modern development teams prefer 2 or 4 spaces. Our tool lets you choose based on your preference or team standards.
Will formatting change how my HTML works?
No. HTML formatting only changes whitespace and layout, not the actual functionality. Browsers ignore extra whitespace when rendering HTML, so formatting won't affect how your page looks or behaves.
How much can I save by minifying HTML?
Typically 10-30% reduction in file size, depending on how much whitespace and comments your HTML contains. For large websites, this can significantly improve loading times.
Can I format embedded JavaScript and CSS?
Our tool focuses on HTML structure. For JavaScript and CSS within script and style tags, you might need dedicated formatters, though basic formatting will still improve readability.
