I want to style a dropdown list with css. I gave it the ID "List1" and then I made a new text file in the "Files" folder in the project bar and renamed it to "List1.css". Then, I typed:
#List1 (pressed enter)
(pressed tab to add a space)Set "font-size" to "3em" (pressed enter)
(pressed tab to add a space)Set "background-color" to "black"
but nothing happened.
What do I need to do to style the list or anything that can be styled with css code?
