HTML Formatter
Beautify and format HTML code with proper indentation, tag alignment, and consistent style.
About HTML Formatting
Well-formatted HTML is easier to read, debug, and maintain. Consistent indentation shows the document structure at a glance — nested elements are visually offset from their parents. This formatter parses HTML tags, handles void elements (br, hr, img, input, link, meta), and applies consistent indentation. Inline elements (span, a, strong, em) are treated differently from block elements to preserve text flow.
FAQ
Should I use 2 or 4 spaces for HTML indentation?
HTML tends to nest deeply (html → head/body → div → div → p → span...), so 2 spaces is more common in HTML to prevent lines from becoming excessively long. 4 spaces is the standard for Python, Java, and PHP. Most team style guides use 2 spaces for HTML/CSS/JavaScript and configure this in an .editorconfig file.
