HTML Boilerplate Generator
Fill in title, viewport and metadata options to get a clean HTML5 starter document.
What is Boilerplate?
A starter-document generator. Instead of memorising the order of the head's meta tags, you fill in the title, description and asset paths and get a document that is correct by construction.
How it works
Fields are escaped before they are written into attributes or text, the charset meta comes first so the browser cannot misdecode a title with accents, and the script is emitted with `defer` so it never blocks the first paint. Open Graph and Twitter tags are generated as a pair so the two previews cannot drift apart.
- Paste the source. Drop in code, a stylesheet, a query or a selector list. Everything is read locally — the page never uploads what you paste.
- Choose the options. Indent width, quote style, keyword case or target browsers. The result updates as you change them, so you can see the effect immediately.
- Copy or download. Copy the result to the clipboard or download it as a file. Reset clears the form and returns every option to its default.
Examples
A landing page skeleton
Title, description, stylesheet, favicon and Open Graph image produce a document that already previews correctly when shared.
A minimal test fixture
Turn Open Graph off for a three-line document that is perfect for testing markup or CSS in isolation.
Common mistakes
Expecting a formatter to fix invalid code
Formatting is whitespace and quoting. A missing brace, an unclosed tag or an unquoted variable survives the round trip and is reported instead — check the findings list.
Minifying without running the tests afterwards
Even a safe, non-mangling minifier can expose an existing automatic-semicolon-insertion bug. The JavaScript Minifier keeps the newlines that matter, but re-run your tests before shipping.
Treating a rewritten query as verified
The SQL Dialect Converter translates the syntax it can prove; data types, casts and function differences are listed for review, not guessed. Run the converted query against a real database.
Renaming or reformatting generated files
Regenerating a formatter's output is a no-op only if the formatter is the same one that produced it. Keep generated code out of the round trip and format the source it came from.
Frequently asked questions
Why is the charset tag first?
The browser needs the encoding before it can correctly read the rest of the head — including the title, which often contains accents. The HTML specification recommends declaring it within the first 1024 bytes.
Do I need all the social tags?
Only if the page will be shared. They are one switch here, and leaving them on costs a few hundred bytes while preventing the broken-preview problem when somebody posts the link.
Is the output a full page?
It is a document skeleton with a heading and paragraph, or whatever you put in the body field. It deliberately includes no framework, no CSS reset and no script logic so you can add exactly what you need.
