Responsive Landing Page

What did you find difficult while building the project?

While targeting two different screens. I find myself re-structuring the HTML page multiple times. I don't know if it is best practice. I want to study the layout concepts like creating a blueprint layout and then starting to replicate the actual design. How many screens should be targeted?

Which areas of your code are you unsure of?

I may have repeated some code again and at the menu button.

Do you have any questions about best practices? I would like to know some best practices that should be followed when creating a web page.

I am on the way to learning transitions and animations. Any suggestions would be helpful.

thank you
