Frequently Asked Questions
Will formatting change how my page renders?
No - only whitespace and indentation are adjusted; tags, attributes, and content are left exactly as you wrote them.
Does it fix unclosed or mismatched tags?
It won't auto-repair broken markup, but a badly nested tag becomes visually obvious once the indentation is applied, making it easy to spot.
Can I use this for HTML email templates?
Yes - it works on any HTML fragment, including inline-styled email markup, without stripping your `style` attributes.
