What does adding height option does?


What is the use of adding height css element in code, I can see the changes , but I cannot understand , what its actually doing.



it's obvious adding height is to make your class selector (the .jumbotron) section tobe 500px height, if its not affecting thats mean you wrong at the selector .jumbotron is a class selector & #jumbotron is id selector. Look at html code is it a class or id or something else.
