Difference between #id and div#id

Question

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

Answer 1

#test will take the element with the id test while div#test will only take the div with an id named test. This doesn't make a great difference since ids have to be unique.

This kind of info is pretty easy to find, you may want to take a look at W3schools documentation
