What is a mobile first design?

What is Mobile-First Design? As the term suggests, mobile-first design is an approach in which web designers start product design for mobile devices first. This can be done by sketching or prototyping the web app's design for the smallest screen first and gradually working up to larger screen sizes.

What means mobile first?

A “mobile-first” approach involves designing a desktop site starting with the mobile version, which is then adapted to larger screens (contrary to the traditional approach of starting with a desktop site and then adapting it to smaller screens).

Why was mobile designed first?

Mobile-first design is a key ingredient to successful product design. Designing for the smallest screens first, and then working your way up empowers designers to focus on the core functions of their product.

What is mobile first architecture?

Essentially, the aim of mobile first is to switch the workflow from tackling desktop designs first and addressing the mobile design head on, working towards the desktop version as the project evolves. With Mobile First, developers have the flexibility to scale up rather than scale down.
