Common Mistakes to Avoid

⚠️

Removing whitespace in <pre> or <code>

Solution: Preformatted text blocks need whitespace preserved. Good minifiers detect and skip these elements.

⚠️

Breaking inline-block spacing

Solution: Inline elements use whitespace for spacing. Removing it can cause layout issues. Test thoroughly.

⚠️

Not keeping source files

Solution: Never edit minified HTML directly. Keep readable source files and minify only for production.
