Difference between #id and div#id

Question

I am new to css. Can someone help me in differentiating \"#test\" and \"div#test\"?

Answer 1

The #id is Selects the element with id="firstname". It is one kind of CSS Selectors.

Check all CSS Selectors at https://www.w3schools.com/cssref/css_selectors.asp

There is a minor difference.

When you use div#id it will only apply to #id that are attached to a div. Otherwise the rule is ignored.

Hope it helps. Thanks
