What is an HTML code formatter?

An HTML code formatter automatically applies consistent indentation and line breaks to HTML, making it easier to read and maintain.

Can I format HTML that includes PHP or template tags?

The formatter handles pure HTML. Template tags (PHP, Jinja, etc.) may be preserved as-is but are not specifically formatted.

Real-world examples

Common situations where this approach makes a real difference:

Normalising HTML across a team project

Multiple developers with different editors produce files with mixed tabs and spaces. Running all files through the formatter standardises indentation before merging into a shared branch.

Formatting a component library

HTML component examples in a design system need to follow a strict style guide. The formatter ensures every example is consistently indented before publishing.

When to use this guide

Use this when establishing or enforcing a consistent code style across HTML files in a project, especially before a major refactor or code review.

Pro tips

Get better results with these expert suggestions:

Format all files before a refactor

Normalize the formatting of every HTML file in a project before starting a structural refactor. This prevents misleading diffs caused purely by whitespace.

Use consistent self-closing tag style

Decide early whether to use self-closing tags (e.g., <br /> vs <br>). The formatter respects your HTML5 syntax — just pick one convention and keep it.

Format snippets before adding to templates

When copying HTML from external sources, format it first to ensure it matches your project's indentation style before inserting.
