Format HTML before you publish
Readable markup catches nesting mistakes early and speeds up PR review.
Key takeaways
- Format for review; minify only at the release step when byte size matters.
- After formatting, spot-check unclosed tags and attribute quoting in the diff.
When formatting helps
Use formatting when HTML is generated, copied from CMS exports, or merged from partials—indentation makes sibling/nesting errors obvious.
Skip aggressive minification during development; reviewers need structure, not one-line blobs.
Suggested workflow
Paste markup into HTML Formatter, choose beautify, and scan the diff for stray closing tags.
If the page includes user-generated fragments, run HTML entity encoding on samples before embedding.
FAQ
Does formatting change page behavior?
Whitespace between tags usually does not, but always verify scripts and inline handlers in a staging build.
Should I format email HTML the same way?
Email clients are picky—test templates separately; web page formatting rules may not apply.
