Huddle_landing_page_with_a_single_introductory_section / Flex-Box

Hello, although in appearance it is the same as the design of the challenge, I am not satisfied, it has taken me a bit to work on the Responsive to give it better fluidity, I feel a little stuck because it has already happened to me with several projects, I am going to continue learning to use more CSS properties to optimize my code.

If you have any suggestions, I will be very grateful.
