Frequently Asked Questions
Why format HTML?
Properly formatted HTML improves code readability, makes maintenance easier, and helps identify structural issues. It's essential for team collaboration and code review.
What is attribute sorting?
Attribute sorting arranges HTML attributes alphabetically within tags, creating consistent ordering that makes attributes easier to find and maintain.
How does syntax validation help?
Syntax validation catches common HTML errors, ensuring your code is well-formed and follows HTML standards before being used in production.
Will formatting affect functionality?
No, proper HTML formatting only changes the code's appearance, not its functionality. The rendered output remains the same.
