The concept of mobile first web design is about designing your website for mobile devices and the smallest screen size first, and then scaling it up to suit the bigger screen sizes. Often called responsive design, as it means having just one website that responds to the users’ screen size, rather than separate websites for mobile and desktop users.
By starting to design for the smallest screen first, you will automatically include only the most essential design points, content and features. This ensures that the user experience for mobile users is put first, ensuring they can access all the vital information without missing out on anything. That way, anything added into the site to appear on larger screens are ‘luxury’ additions, often called ‘progressive enhancements’.
Mobile-first designs also champion ‘content-first.’ As designing for the smallest screen places more limitations on the design, it means that you and your web designers have to prioritise your content efficiently.
As a result, your content should be written and created, in order of priority, and the rest of the site can be designed around this content to ensure you’re providing the most useful information to your customers, no matter what device they are on.
