A universal selector is indeed the * This is useful when you want to set a style for of all the elements of an HTML page For example you may want to set the color for your entire page to blue. Instead of targeting each element one by one, you may type:

  • { color: blue; }

That way, all elements will have the color:blue. An asterisk can also be followed by a selector so you can set a style for all of the elements within an element of an HTML page.

In general, using universal selectors in not considered a best practice, but they may come in handy in some cases (at least that is what is mentioned in the course, since I do not have any experience of front-end development)

Hope that helps :)
