Fylo dark theme landing page full responsive using HTML, CSS and JS

My process broke down into:

1. Identify specific sections by analyzing the interface design (header, hero, features, ecc...)

2. Focus on writing the HTML content for each section while respecting the semantics of the contents

3. Style each section with CSS

4. Additional features such as smooth scrolling and email checking feedback on submit

5. Media Queries and extra

Is there any point where I could improve? Do you have more detailed workflows to share? Any response is greatly appreciated ;)
