Direct answer

The most common risk when working with html-minifier is accepting a plausible-looking result without checking tag nesting, attributes, accessibility and rendered output.

Key takeaways

  • Purpose: reduce unnecessary characters without changing semantics.
  • Check: tag nesting, attributes, accessibility and rendered output.
  • Limitation: syntactically valid markup may still render differently across browsers.

Common mistakes

  • Assuming the output is correct because the operation completed. Instead, inspect tag nesting, attributes, accessibility and rendered output.
  • Using production or confidential material as the first test. Use a short article fragment with a heading, link and list instead.
  • Ignoring compatibility: syntactically valid markup may still render differently across browsers.
