Strive for Clarity
It can be challenging to design for smaller displays and still get your point across. Focus on the clarity of the content and provide strong visual cues for how a user should interact with content and navigation.
Focus on the usability of the experience and what you can do to help users achieve their goals in the most efficient way possible.
Don’t assume that users will know to swipe content or understand that tapping on an element reveals a slidedown accordion. It’s up to you to make those interactions easily understood.
