Root and asterisk selector

HTML-CSS
1

What’s the difference between :root and * selector in css. Doesn’t both of them do the same thing?

No, :root is the root element, the toppermost element in in the DOM tree - it’s <html></html> if it’s an HTML page (but not if it’s an SVG or XML document)

* just means “select everything”: * { padding: 0; } would set padding to 0 on every element.
