I have heard that a lot from my web design clients through the years. From how their users will navigate a website differently, trust me. My clients can be trusted and we won’t need that extra security step. But recently it seems to be regarding their perceived mobile audience. If you think “your clients are different”, and a mobile presence is unnecessary, just stop and think about how many people you know in your business and personal life right now that don’t own a smartphone or tablet ?
Mobile First design is becoming the standard for web design. Adapting a design to be responsive after it's designed for a fixed-width screen is not an easy task.
Proposing a 'mobile first design' philosophy to clients isn't an easy sell. Your client probably expects you to design for standard-sized monitors and adapt the design for smaller devices afterwards. Designing for standard monitors first is a sure way to cost additional time and money vs. mobile first design.
M(dot) domains were short lived and by the end of 2012, responsive design took over.
As a web designer one thing I can say for sure is that if you blink, you may miss the next new thing. With the incredible surge in mobile devices, mini laptops and tablets as well as the desktop display getting larger, designing a website that is responsive to the device is a must.
There is a lot of talk in the internet world about "responsive design".
Responsive web design is a web designers answer to designing a website that works on everything from the smallest browser enabled phone to the largest desktop monitor. An example of responsive design can be seen on this website. To demonstrate below are 3 screenshots of this website. Without any redirect or sub-domain the user is shown the appropriate layout below based on the device the site is being viewed on.
