Frequently Asked Questions — HTML Formatter & Beautifier
How does the HTML formatter handle inline vs block elements?
Block-level elements like div, section, and p are placed on their own lines with proper indentation. Inline elements like span, strong, and a are kept on the same line as their surrounding text to maintain readability and correct rendering.
Does it fix broken HTML?
The formatter handles minor issues like missing closing tags and improper nesting by reformatting based on the parsed DOM structure. However, it is not a full HTML repair tool. Severely malformed HTML should be manually reviewed.
Can I minify HTML for production?
Yes. The Minify button removes all unnecessary whitespace, comments, and line breaks to produce the smallest possible HTML output. This reduces file size and improves page load times for production websites.
