HTML Formatter
The HTML Formatter beautifies minified or messy HTML code by adding proper indentation, line breaks, and spacing. Well-formatted HTML is easier to read, debug, and maintain. This formatter follows common HTML style conventions, adding newlines after each tag, indenting nested elements, and aligning attributes. It is perfect for working with minified HTML from production or cleaning up auto-generated markup.
Formula
Formatting adds: - Newline after each tag - Indentation for nested elements (2 spaces) - Line breaks for attributes - Consistent quote style - Proper closing tags Result: readable HTML
Example
Input (minified): <div class="container"><h1>Title</h1><p>Text</p></div> Output (formatted): <div class="container"> <h1>Title</h1> <p>Text</p> </div>
How to Use
- Paste your HTML code into the input field
- Select indentation size (2 or 4 spaces)
- Click format to beautify the HTML
- Review the readable output
- Copy the formatted HTML for development
Frequently Asked Questions
What HTML formatting style is used?
The formatter uses a common style: each block element on its own line, nested elements indented with 2 spaces, inline elements kept on the same line. This is similar to Prettier's HTML formatting.
Can formatting change HTML rendering?
No. Formatting only adds whitespace for readability. The HTML renders identically. However, be careful with pre and textarea elements, where whitespace is significant and formatting can change rendering.
Should I format HTML for production?
No. Use minified HTML for production (smaller file size). Keep formatted HTML for development and debugging. Most frameworks automatically minify HTML for production builds.
Does the formatter handle templating syntax?
The formatter works on standard HTML. For templating languages like Jinja, EJS, or Handlebars, the formatter may not understand template syntax and could misformat it. Use a dedicated formatter for your templating language.
Can I customize the formatting style?
The formatter offers options for indentation size (2 or 4 spaces), whether to put attributes on separate lines, and how to handle void elements (self-closing or not). Choose the style that matches your team's convention.
