What does HTML formatting do?
HTML formatting adds proper indentation to nested elements, making the document structure clear. It puts each element on its own line and indents child elements. This makes it easier to understand the page structure and spot missing closing tags.
When should I minify HTML?
Minify HTML for production to reduce file size. Minified HTML removes unnecessary whitespace, comments, and optional closing tags. For most websites, HTML minification is handled by build tools or CDNs automatically.
Does formatting change how my HTML renders?
No. Formatting only changes whitespace between tags. It does not modify element attributes, content, or structure. The browser renders the page the same way. However, be careful with <pre> and <code> elements — whitespace inside them is preserved.
