Tribute page grid problem

Hello, I have problem with grid in my tribute page. I want to make tribute page which is responsive to mobiles by using grid and I don’t know where I made mistake or maybe I didn’t add something. I am fighting with it about 2 hours, I tried to search explantations in google but I didn’t find anything. Can you help me?

You do not have a .main class, you have an element main with an id of #main.

Also the syntax you were using (you fixed it).

@media (width <= 500px)

Is not yet supported by browsers (might be behind a config, not sure), it is part of the upcoming Media Queries Level 4

Oh my god thank you! I thought that @media (width <= 500px) won’t work but I really didn’t know what to do so I tried even this :smiley:
