Question 1

Why should I format my HTML?

Accepted Answer

Formatted HTML is easier to read, debug, and maintain. Consistent indentation makes nesting errors visible at a glance and helps teams follow a shared style. While browsers parse unformatted HTML fine, humans and linters benefit greatly from clean structure.

Question 2

Does HTML formatting affect page performance?

Accepted Answer

Formatted HTML is slightly larger than minified HTML due to whitespace. For production, minify your HTML to reduce bytes sent over the wire. Use a formatter during development for readability, then minify in your build pipeline before deployment.
