The debate between tabs and spaces has raged for decades. When it comes to HTML formatting, consistency is the only rule that truly matters.
The Case for Spaces
Spaces guarantee that the code will look exactly the same across every editor, browser, and operating system. 2 or 4 spaces are the industry standard for HTML.
The Case for Tabs
Tabs are more accessible. A visually impaired developer can set their tab width to 8 spaces for readability, while a developer on a small laptop can set it to 2, without changing the underlying file.
The Solution
Use an HTML formatter to enforce whichever standard your team chooses. The tool can instantly convert tabs to spaces, or spaces to tabs, eliminating the debate entirely.
